multiple fs option at one time
for marvell soc family
-- 8xx CPU Options: (if using an MPC8xx CPU)
- CONFIG_8xx_GCLK_FREQ - deprecated: CPU clock if
- get_gclk_freq() cannot work
- e.g. if there is no 32KHz
- reference PIT/RTC clock
- CONFIG_8xx_OSCLK - PLL input clock (either EXTCLK
- or XTAL/EXTAL)
-
-- 859/866/885 CPU options: (if using a MPC859 or MPC866 or MPC885 CPU):
- CONFIG_SYS_8xx_CPUCLK_MIN
- CONFIG_SYS_8xx_CPUCLK_MAX
- CONFIG_8xx_CPUCLK_DEFAULT
- See doc/README.MPC866
-
- CONFIG_SYS_MEASURE_CPUCLK
-
- Define this to measure the actual CPU clock instead
- of relying on the correctness of the configured
- values. Mostly useful for board bringup to make sure
- the PLL is locked at the intended frequency. Note
- that this requires a (stable) reference clock (32 kHz
- RTC clock or CONFIG_SYS_8XX_XIN)
-
- CONFIG_SYS_DELAYED_ICACHE
-
- Define this option if you want to enable the
- ICache only when Code runs from RAM.
-
- 85xx CPU Options:
CONFIG_SYS_PPC64
Define this variable to enable hw flow control in serial driver.
Current user of this option is drivers/serial/nsl16550.c driver
-- Console Interface:
- Depending on board, define exactly one serial port
- (like CONFIG_8xx_CONS_SMC1, CONFIG_8xx_CONS_SMC2,
- CONFIG_8xx_CONS_SCC1, ...), or switch off the serial
- console by defining CONFIG_8xx_CONS_NONE
-
- Note: if CONFIG_8xx_CONS_NONE is defined, the serial
- port routines must be defined elsewhere
- (i.e. serial_init(), serial_getc(), ...)
-
- Console Baudrate:
CONFIG_BAUDRATE - in bps
Select one of the baudrates listed in
CONFIG_SYS_BAUDRATE_TABLE, see below.
- CONFIG_SYS_BRGCLK_PRESCALE, baudrate prescale
-
-- Console Rx buffer length
- With CONFIG_SYS_SMC_RXBUFLEN it is possible to define
- the maximum receive buffer length for the SMC.
- This option is actual only for 82xx and 8xx possible.
- If using CONFIG_SYS_SMC_RXBUFLEN also CONFIG_SYS_MAXIDLE
- must be defined, to setup the maximum idle timeout for
- the SMC.
- Autoboot Command:
CONFIG_BOOTCOMMAND
Note: Don't enable the "icache" and "dcache" commands
(configuration option CONFIG_CMD_CACHE) unless you know
what you (and your U-Boot users) are doing. Data
- cache cannot be enabled on systems like the 8xx or
+ cache cannot be enabled on systems like the
8260 (where accesses to the IMMR region must be
uncached), and it cannot be disabled on all other
systems where we (mis-) use the data cache to hold an
CONFIG_WATCHDOG
If this variable is defined, it enables watchdog
support for the SoC. There must be support in the SoC
- specific code for a watchdog. For the 8xx and 8260
- CPUs, the SIU Watchdog feature is enabled in the SYPCR
- register. When supported for a specific SoC is
- available, then no further board specific code should
- be needed to use it.
+ specific code for a watchdog. When supported for a
+ specific SoC is available, then no further board specific
+ code should be needed to use it.
CONFIG_HW_WATCHDOG
When using a watchdog circuitry external to the used
has to be selected, too. Define exactly one of the
following options:
- CONFIG_RTC_MPC8xx - use internal RTC of MPC8xx
CONFIG_RTC_PCF8563 - use Philips PCF8563 RTC
CONFIG_RTC_MC13XXX - use MC13783 or MC13892 RTC
CONFIG_RTC_MC146818 - use MC146818 RTC
Define this if you want stdin, stdout &/or stderr to
be set to usbtty.
- mpc8xx:
- CONFIG_SYS_USB_EXTC_CLK 0xBLAH
- Derive USB clock from external clock "blah"
- - CONFIG_SYS_USB_EXTC_CLK 0x02
-
If you have a USB-IF assigned VendorID then you may wish to
define your own vendor specific values either in BoardName.h
or directly in usbd_vendor_info.h. If you don't define
Defining CONFIG_CAN_DRIVER enables CAN driver support
on those systems that support this (optional)
- feature, like the TQM8xxL modules.
+ feature.
- I2C Support: CONFIG_SYS_I2C
eg: #define I2C_INIT (immr->im_cpm.cp_pbdir |= PB_SCL)
- I2C_PORT
-
- (Only for MPC8260 CPU). The I/O port to use (the code
- assumes both bits are on the same port). Valid values
- are 0..3 for ports A..D.
-
I2C_ACTIVE
The code necessary to make the I2C data line active
following board configurations are known to be
"pRAM-clean":
- IVMS8, IVML24, SPD8xx, TQM8xxL,
+ IVMS8, IVML24, SPD8xx,
HERMES, IP860, RPXlite, LWMON,
- FLAGADM, TQM8260
+ FLAGADM
- Access to physical memory region (> 4GB)
Some basic support is provided for operations on memory not
set. If this value is set, it must be set to the same value as
CONFIG_ENV_SIZE.
-- CONFIG_SYS_SPI_INIT_OFFSET
-
- Defines offset to the initial SPI buffer area in DPRAM. The
- area is used at an early stage (ROM part) if the environment
- is configured to reside in the SPI EEPROM: We need a 520 byte
- scratch DPRAM area. It is used between the two initialization
- calls (spi_init_f() and spi_init_r()). A value of 0xB00 seems
- to be a good choice since it makes it far enough from the
- start of the data area as well as from the stack pointer.
-
Please note that the environment is read-only until the monitor
has been relocated to RAM and a RAM copy of the environment has been
created; also, when using EEPROM you will have to use getenv_f()
- CONFIG_SYS_CACHELINE_SIZE:
Cache Line Size of the CPU.
-- CONFIG_SYS_DEFAULT_IMMR:
- Default address of the IMMR after system reset.
-
- Needed on some 8260 systems (MPC8260ADS, PQ2FADS-ZU,
- and RPXsuper) to be able to adjust the position of
- the IMMR register after a reset.
-
- CONFIG_SYS_CCSRBAR_DEFAULT:
Default (power-on reset) physical address of CCSR on Freescale
PowerPC SOCs.
Virtual address of CCSR. On a 32-bit build, this is typically
the same value as CONFIG_SYS_CCSRBAR_DEFAULT.
- CONFIG_SYS_DEFAULT_IMMR must also be set to this value,
- for cross-platform code that uses that macro instead.
-
- CONFIG_SYS_CCSRBAR_PHYS:
Physical address of CCSR. CCSR can be relocated to a new
physical address, if desired. In this case, this macro should
- CONFIG_SYS_IMMR: Physical address of the Internal Memory.
DO NOT CHANGE unless you know exactly what you're
- doing! (11-4) [MPC8xx/82xx systems only]
+ doing! (11-4) [82xx systems only]
- CONFIG_SYS_INIT_RAM_ADDR:
sequences.
U-Boot uses the following memory types:
- - MPC8xx and MPC8260: IMMR (internal memory of the CPU)
- - MPC824X: data cache
- PPC4xx: data cache
- CONFIG_SYS_GBL_DATA_OFFSET:
point to an otherwise UNUSED address space between
the top of RAM and the start of the PCI space.

Note that this is a global option, we can't
To be able to re-map memory U-Boot then jumps to its link address.
To be able to implement the initialization code in C, a (small!)
initial stack is set up in the internal Dual Ported RAM (in case CPUs

Next, all (potentially) available memory banks are mapped using a
preliminary mapping. For example, we put them on 512 MB boundaries

- * Hard Reset Configuration Word (HRCW) table
- *
- * The Hard Reset Configuration Word (HRCW) sets a number of useful things
- * such as whether there is an external memory controller, whether the
- * PowerPC core is disabled (i.e. only the communications processor is
- * active, accessed by another CPU on the bus), whether using external
- * arbitration, external bus mode, boot port size, core initial prefix,
- * internal space base, boot memory space, etc.
- *
- * These things dictate where the processor begins execution, where the
- * boot ROM appears in memory, the memory controller setup when access
- * boot ROM, etc. The HRCW is *extremely* important.
- *
- * The HRCW is read from the bus during reset. One CPU on the bus will
- * be a hard reset configuration master, any others will be hard reset
- * configuration slaves. The master reads eight HRCWs from flash during
- * reset - the first it uses for itself, the other 7 it communicates to
- * up to 7 configuration slaves by some complicated mechanism, which is
- * not really important here.
- *
- * The configuration master performs 32 successive reads starting at address
- * 0 and incrementing by 8 each read (i.e. on 64 bit boundaries) but only 8
- * bits is read, and always from byte lane D[0-7] (so that port size of the
- * boot device does not matter). The first four reads form the 32 bit HRCW
- * for the master itself. The second four reads form the HRCW for the first
- * slave, and so on, up to seven slaves. The 32 bit HRCW is formed by
- * concatenating the four bytes, with the first read placed in byte 0 (the
- * most significant byte), and so on with the fourth read placed in byte 3
- * (the least significant byte).

-The current implementation allows the user to specify the desired CPU
-clock value, in MHz, via an environment variable "cpuclk".
-
-Four compile-time constants are used:
-
- CONFIG_8xx_OSCLK - input quartz clock
- CONFIG_SYS_8xx_CPUCLK_MIN - minimum allowed CPU clock
- CONFIG_SYS_8xx_CPUCLK_MAX - maximum allowed CPU clock
- CONFIG_8xx_CPUCLK_DEFAULT - default CPU clock value
-
-If the "cpuclk" environment variable value is within the CPUCLK_MIN /
-CPUCLK_MAX limits, the specified value is used. Otherwise, the
-default CPU clock value is set.
-
-Please make sure you understand what you are doing, and understand
-the restrictions of your hardware (board, processor). For example,
-ethernet will stop working for CPU clock frequencies below 25 MHz.
-
-Please note that the new clock-handling code is enabled if
-CONFIG_8xx_CPUCLK_DEFAULT is defined. Since this mechanism supports
-only MPC866 and newer CPUs, this constant MUST NOT be defined for
-MPC823/850/860/862 series. The clock generation algorithm for older
-chips is different and has not been implemented yet. If you need it,
-your patch is welcome.

-Attached is an IDMA example code for MPC8260/PPCBoot. I had tried to
-search around and could not find any for implementing IDMA, so
-implemented one. Its not coded in the best way, but works.
-
-Also, I was able to test the IDMA specific code under Linux also
-(with modifications). My requirement was to implement it for
-CompactFlash implemented in memory mode, and it works for it under
-PPCBoot and Linux.

-Summary:
-========
-
-This file contains information about the port of U-Boot to the
-Motorola mpc5xx series of CPUs. Most of this code is taken from
-existing code mainly from the mpc8xx port. In contrast to mpc8xx,
-the mpc5xx has no CPM, MMU and cache facilities.
-
-The implemented features have been tested on the cmi board, a
-customer specific board (see README.cmi).
-
-Hence this port is only tested on the cmi board further possible
-tests on other boards will be very valuable.
-
-Not Tested Features:
-====================
-
-* System calls
-* Interrupts
-
-Added or Changed Files:

- * 5. For some reason, cbd_datlen is *always* +2 the value it should be.

Tbot provides a way to execute tests on target hardware. It is intended for
trying out both U-Boot and Linux (and potentially other software) on a
number of boards automatically. It can be used to create a continuous test

-What is tbot ?
-==============
-
-tbot is a tool for executing testcases on boards.
-Source code found on [1]
-Based on DUTS [2]
-written in python
-
-Basic Ideas of tbot
-===================
-(see also the figure:
-https://github.com/hsdenx/tbot/blob/master/doc/tbot_structure.png )
-
-- Virtual laboratory (VL)
- VL is the basic environment that groups:
- - [a number of] boards - target devices on which tbot executes testcases.
- - one Lab PC
-
-- Test case (TC):
- A piece of python code, which uses the tbot class from [1].
- Tbot provides functions for sending shell commands and parsing the
- shell commands output.
- Tbot waits endless for a shell commands end (detected through reading
- the consoles prompt).
- A TC can also call other TC-es.
-
- remark:
- Tbot not really waits endless, for a shell commands end, instead
- tbot starts a watchdog in the background, and if it triggers, tbot
- ends the TC as failed. In the tbot beginning there was a lot of
- timeouts / retry cases, but it turned out, that waiting endless
- is robust and easy ...
-
-- Host PC (where tbot runs, currently only linux host tested)
- must not a powerful machine (For example [3], I use a
- raspberry pi for running tbot and buildbot)
-
-- Lab PC:
- - Host PC connects through ssh to the Lab PC
- -> so it is possible to test boards, which
- are not at the same place as the Host PC.
- (Lab PC and Host PC can be the same of course)
- -> maybe we can setup a Testsystem, which does nightly
- U-Boot/Linux builds and test from current mainline U-Boot
- on boards wherever they are accessible.
-
- - necessary tasks a Lab PC must deliver:
- - connect to boards console through a shell command.
- - power on/off boards through a shell command
- - detect the current power state of a board through
- a shell command
-
- - optional tasks:
- - tftp server (for example loading images)
- - nfs server (used as rootfs for linux kernels)
- - Internet access for example for downloading
- U-Boot source with git.
- - toolchains installed for compiling source code
-
- -> a linux machine is preffered.
-
- - currently only Lab PC with an installed linux supported/tested.
-
-- Boards(s):
- the boards on which shell commands are executed.
-
-- Board state:
- equals to the software, the board is currently running.
-
- Currently tbot supports 2 board states:
- - "u-boot", if the board is running U-Boot
- - "linux", if the board is running a linux kernel
-
- It should be easy to add other board states to tbot, see
- https://github.com/hsdenx/tbot/tree/master/src/lab_api/state_[u-boot/linux].py
-
- A board state is detected through analysing the boards
- shell prompt. In linux, tbot sets a special tbot prompt,
- in U-Boot the prompt is static, and configurable in tbot through
- a board config file.
-
- A TC can say in which board state it want to send shell commands.
- Tbot tries to detect the current board state, if board is not in
- the requested board state, tbot tries to switch into the correct
- state. If this fails, the TC fails.
-
- It is possible to switch in a single TC between board states.
-
-- Events
- tbot creates while executing testcases so called events.
- After tbot ended with the testcase it can call event_backends,
- which convert the events to different formats. more info:
-
- https://github.com/hsdenx/tbot/blob/master/doc/README.event
-
- demo for a event backend:
- http://xeidos.ddns.net/tests/test_db_auslesen.php
-
-- tbot cmdline parameters:
-
-$ python2.7 src/common/tbot.py --help
-Usage: tbot.py [options]
-
-Options:
- -h, --help show this help message and exit
- -c CFGFILE, --cfgfile=CFGFILE
- the tbot common configfilename
- -l LOGFILE, --logfile=LOGFILE
- the tbot logfilename, if default, tbot creates a
- defaultnamelogfile
- -t TC, --testcase=TC the testcase which should be run
- -v, --verbose be verbose, print all read/write to stdout
- -w WORKDIR, --workdir=WORKDIR
- set workdir, default os.getcwd()
-$
-
-tbot needs the following files for proper execution:
-
- - tbot board configuration file (option -c):
- A board configuration file contains settings tbot needs to
- connect to the Lab PC and board specific variable settings
- for testcases.
-
- - name of the logfile tbot creates (option -l)
- defaultname: 'log/' + now.strftime("%Y-%m-%d-%H-%M") + '.log'
-
- - tbots working directory (option -w)
-
- - the testcasename tbot executes (option -t)
-
-You are interested and want to use tbot?
-If so, please read on the file:
-tools/tbot/README.install
-
-If not read [3] ;-)

---------------
-[1] https://github.com/hsdenx/tbot
-[2] http://www.denx.de/wiki/DUTS/DUTSDocs
-[3] automated Testsetup with buildbot and tbot doing cyclic tests
- (buildbot used for starting tbot TC and web presentation of the
- results, all testing done through tbot):
- http://xeidos.ddns.net/buildbot/tgrid
- Host PC in Letkes/hungary
- VL in munich/germany
-
- Fancy things are done here, for example:
- - http://xeidos.ddns.net/buildbot/builders/smartweb_dfu/builds/43/steps/shell/logs/tbotlog
- (I try to cleanup the logfile soon, so it is not so filled with crap ;-)
- A first step see here:
- http://xeidos.ddns.net/buildbot/builders/smartweb_dfu/builds/45/steps/shell/logs/tbotlog
- (same TC now with the new loglevel = 'CON' ... not yet perfect)
- Executed steps:
- - clone u-boot.git
- - set toolchain
- - get a list of patchwork patches from my U-Boots ToDo list
- - download all of them, and check them with checkpatch
- and apply them to u-boot.git
- - compile U-Boot for the smartweb board
- - install the resulting images on the smartweb board
- - boot U-boot
- - test DFU
- - more TC should be added here for testing U-Boot
-
- - automatic "git bisect"
- https://github.com/hsdenx/tbot/blob/master/src/tc/tc_board_git_bisect.py
- http://xeidos.ddns.net/buildbot/builders/tqm5200s/builds/3/steps/shell/logs/tbotlog
-
- If a current U-Boot image not works on the tqm5200 board
- this TC can be started. It starts a "git bisect" session,
- and compiles for each step U-Boot, install it on the tqm5200
- board, and tests if U-Boot works !
-
- At the end, it detects the commit, which breaks the board
-
- This TC is not dependend on U-Boot nor on a special board. It
- needs only 3 variables:
- tb.board_git_bisect_get_source_tc: TC which gets the source tree, in which
- "git bisect" should be executed
- tb.board_git_bisect_call_tc: TC which gets called every "git bisect" step,
- which executes commands for detecting if current source code is OK or not.
- This could be a TC which compiles U-Boot, install it on the board and
- executes TC on the new booted U-Boot image. ! Board maybe gets borken,
- as not all U-Boot images work, so you must have a TC which install U-Boot
- image for example through a debugger.
- tb.board_git_bisect_good_commit: last nown good commit id

-ToDo list for tbot
-==================
-
-please look also into the tbot ToDo list.
-https://github.com/hsdenx/tbot/blob/master/ToDo
-
-- cleanup tbot code:
- - remove all retry / timeout pieces of code
- - clean up tbot function names, as I am not good in
- giving function a understandable name ;-)
- - as I am not a python programmer, cleanup whole tbot code
-
-- introduce a "layering" like yocto do, so U-Boot TC can integrated
- into U-Boot source code.
-
- Proposal:
- introduce subdirs in "src/tc"
-
- lab: all lab specific stuff
- lab/common: common lab stuff (for example ssh handling)
- lab/ssh_std: ssh_std specific stuff
-
- u-boot: all u-boot tests
- u-boot/common: common u-boot tc
- u-boot/duts: DUTS tc
- u-boot-dxr2: all u-boot dxr2 board specific tc
-
- board: board tc
- board/common: common board tc
- board/dxr2: all tc for dxr2 board
-
- linux: all linux tc
- linux/common: common linux tc
- linux/dxr2
-
- - move U-Boot special TC to U-Boot source
- -> need a mechanism in tbot, how it gets automatically for example
- U-Boot TC from U-Boot source...
- -> add a consistency checker
-
-- simplify tbot log output (seperate a lot of output which is currently
- in INFO logging level, to another logging level)
- started (new loglevel "CON", whih prints read/write from console only), see:
- https://github.com/hsdenx/tbot/commit/b4ab2567ad8c19ad53f785203159d3c8465a21c6
- - make the timestamp configurable
-
-- Open more than 2 filehandles ?
- Do we need for more complex TC more than 2 filehandles?
-
-- Find a way to document all TC and document all variables they use in an
- automated way.
-
-- write a lot of more TC
-
-- get U-Boot configuration settings from current U-Boot code and use
- them in U-Boot TC-es

-write a new testcase
-=====================
-
-A TC is written in python, so you can use python as usual. For accessing
-the boards console, use functions from the tbotlib, therefore
-
-First import the tbotlib with the line:
-
- from tbotlib import tbot
-
-If your TC uses variables, please add a line which adds them to
-the log file (for debugging purposes):
-
- logging.info("args: %s ...", tb.varname, ...)
-
-Say tbot, for which board state your TC is valid with:
-
- tb.set_board_state("u-boot")
-
-Then you are ready ... and you can use the tbotlib funtions
-for writting/reading to the boards console.
-
-Big fat warning:
-
-A TC must worry about to end only if a board has finished the shell
-command!
-
-Not following this rule, will end in unpredictable behaviour.
-
-(hopefully) useful tbotlib functions
-====================================
-- set the board state, you want to test
- tb.set_board_state(state)
- states are: "u-boot" or "linux"
- If tbot could not set the board state, tbot ends with failure.
-
-- write a command to the boards console:
- tb.eof_write_con(command):
- write the command to the boards console. If this
- fails, tbot ends with failure
-
-- write a command to boards console and wait for prompt:
- tb.eof_write_cmd(fd, command):
- fd: filedescriptor which is used, use tb.channel_con for boards console
- command: command which is written to fd
-
- Wait endless for board prompt
-
-- write a list of commands to boards console:
- tb.eof_write_cmd_list(fd, cmdlist):
- fd: filedescriptor which is used, use tb.channel_con for boards console
- cmdlist: python list of commandstrings which is written to fd
-
-- wait for boards prompt:
- tb.eof_read_end_state_con(retry):
- retry: deprecated, not used anymore, cleanup needed here...
- tbot waits endless for the boards prompt
-
-- write a command, wait for prompt and check, if a string is read
- tb.write_cmd_check(fd, cmd, string):
- fd: filedescriptor which is used, use tb.channel_con for boards console
- cmd: command, which is send to fd
- string: string which should be read from fd
-
- return value:
- True, if string is read and tbot got back boards prompt
- False, else
-
- tb.eof_write_cmd_check(fd, cmd, string):
- same as tb.write_cmd_check(fd, cmd, string) except, that tbot
- ends immediately with Failure, if string is not read.
-
-- read until prompt and search strings:
- tb.readline_and_search_strings(fd, strings):
- fd: filedescriptor which is used, use tb.channel_con for boards console
- strings: python list of strings, which can be read
- If one of this strings is read, this function return the index, which
- string is read. This function shoud be called in a while loop,
- until this function returns 'prompt'
-
-- read a line from filedescriptor:
- not recommended to use, as the TC must check, if tprompt is read for every
- readen line. Also TC must ensure, that it ends only, if prompt is read.
- tb.read_line(fd, retry)
- fd: filedescriptor which is used, use tb.channel_con for boards console
- retry: retry of trying to reead a line
-
- return values:
- True, if a line is read. Readen line in tb.buf[fd]
- False, if something read, but not a complete line
- None, if nothing is read
-
- check if string contains prompt with:
- tb.is_end_fd(fd, string)
- fd: filedescriptor which is used, use tb.channel_con for boards console
- string: buffer, in which a prompt gets searched.
-
-- calling other TC:
- eof_call_tc(name):
- call another TC from "src/tc"
- if the called TC fails with failure, tbot ends with failure
-
- call_tc(name):
- call another TC from "src/tc"
- if the TC which call_tc calls fails, call_tc() returns False, else True
-
-There are more functions, but for writting TC this should be enough. But
-its software, so new useful functions can always pop up.

-install tbot on your PC (linux only tested):
-============================================
-
-- get the source code:
-
-$ git clone https://github.com/hsdenx/tbot.git
-[...]
-$
-
- cd into the tbot directory.
-
-- you need the for running tbot the python paramiko module, see:
- http://www.paramiko.org/installing.html
-
- paramiko is used for handling ssh sessions, and open filedescriptors
- on a ssh connection. Tbot open a ssh connection to a "lab PC" and
- opens on that connection 2 filehandles, one for control functions
- and one for the connection to the boards console. May it is worth
- to think about to open more filehandles and use them in tbot, but
- thats a point in the Todo list ...
-
- See [1] for more infos about tbot principles.
-
-- prepare a directory for storing the logfiles
- and pass it with the commandline option "-l"
- to tbot. Default is the directory "log" in the tbot
- root (don;t forget to create it, if you want to use it)
-
-- If your VL is not yet in tbot source, integrate it
- (This task has only to be done once for your VL):
-
- A VL has, as described in [2] "necessary tasks for a Lab PC" explained,
- 3 tasks:
-
- a) power on/off the board
- b) get power state of the board
- c) connect to the boards console
-
- As tbot sends only shell commands (also to the Lab PC)
- this tasks must be executable through shell commands on your
- Lab PC:
-
- Task a) power on/off board:
- default TC for this task is:
- https://github.com/hsdenx/tbot/blob/master/src/tc/tc_lab_denx_power.py
-
- - now copy this file to for example
- cp src/tc/tc_lab_denx_power.py src/tc/tc_lab_denx_power_XXX.py
- (replace XXX to a proper value)
- and adapt the "remote_power" command from the denx lab to your needs.
-
- As this TC powers on the board for all your boards in your VL,
- you can differ between the boards through the tbot class
- variable "tb.boardlabpowername" (which is in the default case the
- same as "tb.boardname"), but you may need to name the power target
- with an other name than boardname, so you can configure this case.
- The power state "tb.power_state" which the TC has to set
- is "on" for power on, or "off" for power off.
-
- If switching on the power is successful, call "tb.end_tc(True)"
- else "tb.end_tc(False)"
-
- - set in your board config file:
- self.tc_lab_denx_power_tc = 'tc_lab_denx_power_XXX.py'
-
- Task b) power on/off board:
- default TC for this task is:
- https://github.com/hsdenx/tbot/blob/master/src/tc/tc_lab_denx_get_power_state.py
-
- - now copy this file to for example
- (replace XXX to a proper value)
- cp src/tc/tc_lab_denx_get_power_state.py src/tc/tc_lab_denx_get_power_state_XXX.py
- and adapt the commands to your needs.
-
- If the power of the board is on, call "tb.end_tc(True)"
- else "tb.end_tc(False)"
-
- - set in your board config file:
- self.tc_lab_denx_get_power_state_tc = 'tc_lab_denx_get_power_state_XXX.py'
-
- Task c) connect to the boards console:
- default TC for this task is:
- https://github.com/hsdenx/tbot/blob/master/src/tc/tc_lab_denx_connect_to_board.py
-
- - now copy this file to for example
- (replace XXX to a proper value)
- cp src/tc/tc_lab_denx_connect_to_board.py src/tc/tc_lab_denx_connect_to_board_XXX.py
- and adapt the commands to your needs.
-
- If connect fails end this TC with "tb.end_tc(False)"
- else call "tb.end_tc(True)"
-
- If you want to use kermit for connecting to the boards console, you
- can use:
-
- https://github.com/hsdenx/tbot/blob/master/src/tc/tc_workfd_connect_with_kermit.py
-
- Example for such a board in the VL from denx:
- self.tc_lab_denx_connect_to_board_tc = 'tc_workfd_connect_with_kermit.py'
- https://github.com/hsdenx/tbot/blob/master/tbot_dxr2.cfg#L24
-
- Hopefully this works for you too.
-
- - set in your board config file:
- self.tc_lab_denx_connect_to_board_tc = 'tc_lab_denx_connect_to_board_XXX.py'
-
- remarks while writting this:
- - Currently there is only the denx VL. Original idea was to include
- other VL through a seperate class/file in
- https://github.com/hsdenx/tbot/tree/master/src/lab_api
- but it turned out, that if we say "ssh" is the standard way to connect
- to a VL, we can integrate the VL specific tasks through testcases, see
- above, so we should do:
- - rename the "denx" API to a more general name.
- This is a point on my ToDo list ... done, renamed to 'ssh_std'
-
- - the VL specific configuration may moved from the board config files
- and should be collected in VL specific config files, which boards
- config file simple include.
-
-- prepare password.py file:
- This file contains all passwords tbot needs (for example for
- linux login on the boards)
- tbot searches this file in the tbot root directory.
- It is a simple python file, for example:
-
- # passwords for the lab
- if (board == 'lab'):
- if (user == 'hs'):
- password = 'passwordforuserhs'
- if (user == 'root'):
- password = 'passwordforrootuser'
- # passwords for the boards
- elif (board == 'mcx'):
- if (user == 'root'):
- password = 'passwordformcxrootfs'
- else:
- if (user == 'root'):
- password = ''
-
-- prepare board config file
- Each board which is found in the VL needs a tbot configuration file
- pass the config file name with the option '-c' to tbot, tbot searches
- in the root dir for them.
-
- board Example (dxr2 board):
- https://github.com/hsdenx/tbot/blob/master/tbot_dxr2.cfg
-
- Necessary variables:
-
- line 3: boardname, here it is the "etamin" board
- no default value, must be set.
- line 4: boardlabname: name used for connecting to the board
- may differ from tb.boardname, default tb.boardname
- line 5: boardlabpowername: name used for power on/off
- may differ from tb.boardname, default tb.boardname
- line 6: tftpboardname: name used for tftp subdir (from where
- U-Boot loads images for example).
- may differ from tb.boardname, default tb.boardname
- line 7: labprompt: linux prompt tbot sets
- no defaultvalue, must be set (maybe we should introduce
- "ttbott" as default ...
- line 8: debug: If True, adds debug output on the tbot shell
- line 9: debugstatus: enable status debug output on the shell
- line 10: ip: Where tbot finds the Lab PC
- line 11: user: As which user does tbot logs into the Lab PC
- line 12: accept_all: passed to paramiko, accept all connections
- line 13: keepalivetimout: passed to paramiko, timeout for sending
- keepalive message.
- line 14: channel_timeout: passed to paramiko
- line 15: loglevel: tbots loglevel for adding entries into the logfile.
- line 17: wdt_timeout: timeout in seconds for tbots watchdog.
- Watchdog gets triggered if prompt get read.
- line 24: tc_lab_denx_connect_to_board_tc: Which TC is used for
- connecting to the boards console the TC, here:
- https://github.com/hsdenx/tbot/blob/master/src/tc/tc_workfd_connect_with_kermit.py
- line 27: uboot_prompt: boards U-Boot prompt
- line 28: linux_prompt: boards linux prompt
-
- Now comes a list of variables TC needs, this vary from which TC
- you start on the board.
-
-Thats it ... you now can call tbot and hopefully, it works ;-)
-Find an example log [3] for calling simple U-Boot TC for setting
-an U-Boot Environmentvariable.
-
-If you have problems in setting tbot up, please contact me
-(and may give me ssh access to your Lab PC ;-)
-
-If you have running your first TC [3], you may want to write now your own
-TC (and hopefully share them), so continue with:
