Motorola MPC8540ADS and MPC8560ADS board
Xianghua Xiao(X.Xiao@motorola.com)
Created 10/15/03
-----------------------------------------
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 dracom, ON for draco' (single switch to toggle draco.dracom mode)
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)
Ethernet PHY connectors(J47,J56) should be removed if you want to use the ethernet.
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.
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:
DDR: 0x00000000-0x1fffffff (max 512MB)
PCI: 0xe0000000-0xefffffff (256MB)
RIO: 0xf0000000-0xf7ffffff (128MB)
Local SDRAM: 0xf8000000-0xfbffffff (64MB)
Local CSx: 0xfc000000-0xfdefffff (31MB) BCSR,RTC,ATM config,etc.
CCSRBAR: 0xfdf00000-0xfdffffff (1MB)
Flash: 0xfe000000-0xffffffff (max 32MB)
2.2 We are submitting Linux kernel patches for MPC8540 and MPC8560. Hope you will be
able to download them from linuxppc-2.4 public source by the time you are reading
this. Please make sure the kernel's ppcboot.h is consistent with U-Boot's u-boot.h,
then you can use two default configuration files in the kernel source as a test:
arch/ppc/configs/mpc8540ads_defconfig
arch/ppc/configs/mpc8560ads_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)
CONFIG_E500 BOOKE e500 family(Motorola)
CONFIG_MPC85xx MPC8540,MPC8560 and their derivatives
CONFIG_MPC85xx_REV1 MPC85xx Rev 1 Chip, in general you will use a Rev2
chip from Nov.2003. If you still see this definition
while you have a Rev2(and newer) chip,undef this.
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 possible DLL fix needed for Rev1 chip for more stability.
you can disable this if you're having a newer chip.
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
export CROSS_COMPILE=your-cross-compile-prefix(assuming you're using BASH shell)
cd u-boot
make distclean
make MPC8560ADS_config (or make MPC8540ADS_config)
make
4. Note on the 10/100/1000 Ethernet controller:
4.1 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
