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' (single switch to 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. 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 0xe000_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 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_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 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. 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 5.
