Motorola MPC8540ADS and MPC8560ADS board
Xianghua Xiao(X.Xiao@motorola.com)
Created 10/15/03
-----------------------------------------
0. Toolchain
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
http://ftp.gnu.org/gnu/binutils.
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)
SW10[2-6]="all OFF" (turn on CPM SCC for serial port,works for 8540/8560)
SW11[2]='OFF for 8560, ON for 8540' (toggle 8540.8560 mode)
SW11[7]='ON' (rev2), 'OFF' (rev1)
SW4[7-8]="OFF OFF" (enable serial ports,I'm using the top serial connector)
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. For example, if at 66MHz your system
clock showed SW6[0:1] = 01, then at 33MHz SW6[0:1] it should be 10.
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.
2. MEMORY MAP TO WORK WITH LINUX KERNEL
2.1. For the initial bringup, we adopted a consistent memory scheme
between u-boot and linux kernel, you can customize it based on your
system requirements:
0x0000_0000 0x7fff_ffff DDR 2G
0x8000_0000 0x9fff_ffff PCI MEM 512M
0xc000_0000 0xdfff_ffff Rapid IO 512M
0xe000_0000 0xe00f_ffff CCSR 1M
0xe200_0000 0xe2ff_ffff PCI IO 16M
0xf000_0000 0xf7ff_ffff SDRAM 128M
0xf800_0000 0xf80f_ffff BCSR 1M
0xff00_0000 0xffff_ffff FLASH (boot bank) 16M
2.2 We are submitting Linux kernel patches for MPC8540 and MPC8560. You
can download them from linuxppc-2.4 public source. Please make sure the
kernel's ppcboot.h is consistent with U-Boot's u-boot.h. You can use two
default configuration files as your starting points to configure the
kernel:
arch/ppc/configs/mpc8540_ads_defconfig
arch/ppc/configs/mpc8560_ads_defconfig
3. DEFINITIONS AND COMPILATION
3.1 Explanation on NEW definitions in:
include/configs/MPC8540ADS.h
include/configs/MPC8560ADS.h
CONFIG_BOOKE BOOKE(e.g. Motorola MPC85xx, IBM 440, etc)
CONFIG_E500 BOOKE e500 family(Motorola)
CONFIG_MPC85xx MPC8540,MPC8560 and their derivatives
CONFIG_MPC8540 MPC8540 specific
CONFIG_MPC8560 MPC8560 specific
CONFIG_MPC8540ADS MPC8540ADS board specific
CONFIG_MPC8560ADS MPC8560ADS board specific
CONFIG_TSEC_ENET Use on-chip 10/100/1000 ethernet for networking
CONFIG_SPD_EEPROM Use SPD EEPROM for DDR auto configuration, you can
also manual config the DDR after undef this
definition.
CONFIG_DDR_ECC only for ECC DDR module
CONFIG_DDR_DLL DLL fix on some ADS boards needed for more
stability.
CONFIG_RAM_AS_FLASH after define this, you can load U-Boot into
localbus SDRAM and treat localbus SDRAM as a
flash. We use this memory based U-Boot
before flash is working while Metrowerks and
Windriver are still working on their
flash/JTAG tools. 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
Assuming you're using BASH shell:
export CROSS_COMPILE=your-cross-compile-prefix
cd u-boot
make distclean
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 speed 115200
set carrier-watch off
set handshake none
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
(if it hangs, use Ctrl-C to quit)
MPC8560ADS>nm fdf24524
>0
>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
=> tftp 0 u-boot.bin
=> protect off fff80000 ffffffff
=> erase fff80000 ffffffff
=> cp.b 0 fff80000 80000
4.5 Reflash U-Boot with a BDI-2000
BDI> erase 0xFFF80000 0x2000 0x40
BDI> prog 0xfff80000 u-boot.bin.8560ads
BDI> verify
