+# Think Penguin [TPE-R1200 mini WiFi Router v2](https://www.thinkpenguin.com/gnu-linux/free-software-wireless-n-mini-vpn-routerv2-tpe-r1200)\r
+\r
+## Specs\r
+\r
+* SoC: Atheros AR9331\r
+* RAM: 64M\r
+* Flash: 16M NOR + 128M SPI NAND\r
+* NIC: 2 10/100 Ethernet Ports\r
+* USB: 1\r
+* WiFi: Atheros 802.11b/g/n 2.4Ghz\r
+* GPIO: 3 General Purpose and one switch.\r
+* Power: 5v USB\r
+\r
+The TPE-R1200 is a general purpose mini WiFi router\r
+that can be used for a wide range of applications. \r
+Some common uses include:\r
+\r
+* Route all traffic over a VPN when on the go.\r
+* WiFi to ethernet bridge.\r
+* A small web server.\r
+* IRC bouncer.\r
+* Meshnet node (CJDNS, Batman...).\r
+\r
+# Notes\r
+\r
+With the release of v1.5.0, NAND flash support is not available yet. Before upgrading the router,\r
+the u-boot environment variable `bootcount` needs to be set higher than 3. This can be achieved\r
+by ssh'ing into the router and running : \r
+\r
+\r
+`fw_setenv bootcount 4` \r
+\r
+\r
+After rebooting the router,the router can be upgraded using a `nor` image. When upgrading, it is important that any settings\r
+are not saved and that the "Keep Settings" box is unchecked in luci or that the `-n` flag is specified when using `sysupgrade`.\r
+\r
+# Firmware Images\r
+\r
+See our [flavors](https://librecmc.org/flavors.html) page for a description of each type of libreCMC image.\r

+# CCS (Complete Corresponding Source) Requirements
+
+As a Free Software project, libreCMC works to go above and beyond its license
+obligations to be a good neighbor and to promote the ideals of Free
+Software. The project was founded on the idea that everyone should have the
+*freedom* to control the hardware they own, which means being able to fully
+control what it does and what runs on it. To ensure that everyone who uses
+libreCMC continues to have this freedom, a mechanism was added to the build
+system [1] to generate a CCS disk which OEMs and others would be able to
+distribute with devices shipping libreCMC. This was done to ease compliance and
+to push the idea that sources should be provided with a device at the time of
+sale. Shipping a CCS disk ensures that second hand sales of the device can be
+compliant if the disk is handed off with the device.
+
+
+## `make ccsdisk`
+
+A new target was created to build a CCS disk based upon the option of using an
+external repository or to use a local checkout. As it stands, this includes
+everything except for u-boot sources for a given target. In the near future, the
+libreCMC project will start including versions of u-boot for all officially
+supported targets and, going forward, make this a requirement for official
+hardware in libreCMC.
+
+
+## How to use
+
+There are two ways to use CCS disk : enable "Build the libreCMC CCS Disk" during
+image configuration or run `make ccsdisk` after all desired firmware images have
+been built. Since u-boot for a given target most likely is missing, it's
+important that the sources for u-boot be packaged and included on the disk. To
+do this, make sure they are included in `target/ccsdisk/files` with proper
+documentation. To make things a little bit easier, enabling the toolchain option
+during image configuration and using the toolchain to build u-boot will make
+things go much easier if it can be done.
+
+
+
+[1] libreCMC is a fork of OpenWrt, which both use a fork of
+[Buildroot](https://buildroot.org). Buildroot is a build system which helps to
+make it easier to create firmware images for "embedded" devices.

+ The libre embedded GNU/Linux distro.
+
+This compact disk contains the source code and firmware images
+for the %T line of routers.
+
+
+Disk Layout:
+============================
+
+/bin/%T/* : Contains firmware images for %T family of routers
+
+
+libreCMC-%V-src.tar.gz : The full libreCMC source code w/ original configuration.
+
+
+Building libreCMC image from source:
+============================
+
+To build your own firmware, you need to have access to a GNU/Linux system
+(case-sensitive filesystem required) with the following installed :
+
+gcc, binutils, bzip2, flex, python, perl, make, find,
+grep, diff, unzip, gawk, getopt, libssl-dev (openssl-devel), libz-dev and libc headers.
+
+References to this and other documentation use : "$LIBRECMC_SRC" , which
+is the directory where the libreCMC source code resides.
+
+Before starting, please extract : libreCMC-%V.tar.gz
+
+tar fxv librecmc-%V.tar.gz
+
+cd libreCMC/
+
+Within the libreCMC src. directory (in this case, trunk), please use "make menuconfig" to create your
+desired configuration for the toolchain and firmware. Please note that the default configuration is
+what was used to build the firmware image for your router. It is advised that you use this configuration. If
+you need to restore the default configuration, copy librecmc_config to libreCMC/trunk/.config
+
+Simply running "make" will build your firmware. The build system will extract all included sources,
+build the cross-compile toolchain, the kernel and all chosen applications. If there is an issue, please run:
+
+make V=s
+
+This will show debugging output and give a clue as to why the build failed.
+
+When the build completes without any issues, the resulting librecmc-ar71xx-generic-tpe-r1100-squashfs-sysupgrade.bin image will
+be found in : $SRC_ROOT/bin/targets/ar71xx/
+

+1) Open a web browser and go to : https://192.168.10.1
+
+2) You will see a security warning because SSL cert is self-
+signed. Click the "understand the risks" and then "add exception" buttons.
+
+3) Enter the admin password for the router (stock password is : none )
+
+4) The backup / flash utility is under "System -> Backup / Flash Firmware".
+
+5) Make sure to backup your configuration (if you are upgrading to a new release)
+by clicking the "Generate archive" button. This will download a file named
+backup-libreCMC-$(DATE).tar.gz
+
+6) Upload the new firmware by clicking the "browse" button under "Flash new firmware image".
+If you wish to keep your current settings, make sure that the "Keep Settings" checkbox is
+checked. If the file name is correct, make sure to click the "Flash Image" button.
+
+7) Wait a about 1 - 2.5 min. The router will restart itself then the page should refresh, bringing
+you back to the login page.

+
+ gcc: prevent the use of LDRD/STRD on ARMv5TE
+
+ These instructions are for 64-bit load/store. On ARMv5TE, the CPU
+ requires addresses to be aligned to 64-bit. When misaligned, behavior is
+ undefined (effectively either loads the same word twice on LDRD, or
+ corrupts surrounding memory on STRD).
+
+ On ARMv6 and newer, unaligned access is safe.
+
+ Removing these instructions for ARMv5TE is necessary, because GCC
+ ignores alignment information in pointers and does unsafe optimizations
+ that have shown up as bugs in various places.

+ The .init and .fini sections are built by concatenating code

+

+Author: Felix Fietkau <nbd@openwrt.org>
+Date: Tue Jul 31 00:52:27 2007 +0000
+
+ Port the mbsd_multi patch from freewrt, which adds -fhonour-copts. This will emit warnings in packages that don't use our target cflags properly
+
+ SVN-Revision: 8256
+
+ This patch brings over a feature from MirBSD:
+ * -fhonour-copts
+ If this option is not given, it's warned (depending
+ on environment variables). This is to catch errors
+ of misbuilt packages which override CFLAGS themselves.
+
+ This patch was authored by Thorsten Glaser <tg at mirbsd.de>
+ with copyright assignment to the FSF in effect.

+I talked to Andrew about what files he changed in GCC and created and
+tested this new patch. Andrew also mentioned changing some assembly
+files in glibc but I don't see any use of '.section .note.GNU-stack' in
+any assembly files in glibc (for any platform) so I wasn't planning on
+creating a glibc to add them to mips glibc assembly language files.
+
+OK to check in this patch?

+ gcc: don't clobber stamp-bits with a symlink to itself
+
+ Several versions of gcc have an issue in libstdc++v3 where the build may
+ clobber stamp-bits with a link to itself. This doesn't manifest itself
+ on all systems. On several Ubuntu systems, this doesn't appear to be a
+ problem, but it is an issue on Fedora 16 systems.
+
+ To fix the issue, we'll simply filter out stamp-bits from the symlinks
+ to be generated.
+
+ Note: gcc 4.4.7 is unaffected by this issue, so no fix is necessary
+ there.

+Subject: [PATCH] gotools: fix compilation when making cross compiler
+
+libgo is "the runtime support library for the Go programming language.
+This library is intended for use with the Go frontend."
+
+gccgo will link target files with libgo.so which depends on libgcc_s.so.1, but
+the linker will complain that it cannot find it. That's because shared libgcc
+is not present in the install directory yet. libgo.so was made without problem
+because gcc will emit -lgcc_s when compiled with -shared option. When gotools
+were being made, it was supplied with -static-libgcc thus no link option was
+provided. Check LIBGO in gcc/go/gcc-spec.c for how gccgo make a builtin spec
+for linking with libgo.so
+
+- GccgoCrossCompilation, https://github.com/golang/go/wiki/GccgoCrossCompilation
+- Cross-building instructions, http://www.eglibc.org/archives/patches/msg00078.html
+
+When 3-pass GCC compilation is used, shared libgcc runtime libraries will be
+available after gcc pass2 completed and will meet the gotools link requirement
+at gcc pass3
