0. Toolchain
-The Binutils in current ELDK toolchain will not support MPC85xx chip. You need
-use the newest binutils-2.14.tar.bz2 from http://ftp.gnu.org/gnu/binutils.
+The Binutils in ELDK toolchain 3.0 or earlier does not support the
+MPC85xx chip. You need use the newest binutils-2.14.tar.bz2 from

1. SWITCH SETTINGS & JUMPERS
+
1.1 First, make sure the board default setting is consistent with the document
shipped with your board. Then apply the following changes:
SW3[1-6]="all OFF" (boot from 32bit flash, no boot sequence is used)
SW22[1-4]="OFF OFF ON OFF"
SW5[1-10[="ON ON OFF OFF OFF OFF OFF OFF OFF OFF"
J1 = "Enable Prog" (Make sure your flash is programmable for development)
+
1.2 If you want to test PCI functionality with a 33Mhz PCI card, you will
have to change the system clock from the default 66Mhz to 33Mhz by
setting SW15[1]="OFF" and SW17[8]="OFF". After that you may also need
double your platform clock(SW6) because the system clock is now only
- half of its original value.
+ half of its original value.
+
1.3 SW6 is a very important switch, it decides your platform clock and CPU
clock based on the on-board system clock(default 66MHz). Check the
document along with your board for details.
between u-boot and linux kernel, you can customize it based on your
system requirements:
- 0x0000_0000 0x7fff_ffff DDR 2G
+ 0x0000_0000 0x7fff_ffff DDR 2G
0x8000_0000 0x9fff_ffff PCI MEM 512M
0xc000_0000 0xdfff_ffff Rapid IO 512M
0xe000_0000 0xe000_ffff CCSR 1M

arch/ppc/configs/mpc8560_ads_defconfig
+
3. DEFINITIONS AND COMPILATION
+
3.1 Explanation on NEW definitions in include/configs/MPC8540ADS.h and include/
configs/MPC8560ADS.h
CONFIG_BOOKE BOOKE(e.g. Motorola MPC85xx, IBM 440, etc)
if you can program the flash directly, undef this.
Other than the above definitions, the rest in the config files are straightforward.
-
3.2 Compilation
export CROSS_COMPILE=your-cross-compile-prefix(assuming you're using BASH shell)
cd u-boot
make MPC8560ADS_config (or make MPC8540ADS_config)
make
+
4. Notes:
+
4.1 When connecting with kermit, the following commands must be present.in
your .kermrc file. These are especially important when booting as
MPC8560, as the serial console will not work without them:
set flow-control none
robust
-
4.2 Sometimes after U-Boot is up, the 'tftp' won't work well with TSEC ethernet. If that
happens, you can try the following steps to make network work:
MPC8560ADS>tftp 1000000 pImage
>1
>. (to quit this memory operation)
MPC8560ADS>tftp 1000000 pImage
-4.3 If you're one of the early developers using the Rev1 8540/8560 chips, please use U-Boot
- 1.0.0, as the newer silicon will only support Rev2 and future revisions of 8540/8560.

4.4 Reflash U-boot Image using U-boot
