1 Motorola MPC8540ADS and MPC8560ADS board
3 Xianghua Xiao(X.Xiao@motorola.com)
5 -----------------------------------------
8 The Binutils in ELDK toolchain 3.0 or earlier does not support the
9 MPC85xx chip. You need use the newest binutils-2.14.tar.bz2 from
10 http://ftp.gnu.org/gnu/binutils.
12 1. SWITCH SETTINGS & JUMPERS
14 1.1 First, make sure the board default setting is consistent with the document
15 shipped with your board. Then apply the following changes:
16 SW3[1-6]="all OFF" (boot from 32bit flash, no boot sequence is used)
17 SW10[2-6]="all OFF" (turn on CPM SCC for serial port,works for 8540/8560)
18 SW11[2]='OFF for 8560, ON for 8540' (single switch to toggle 8540.8560 mode)
19 SW11[7]='ON' (rev2), 'OFF' (rev1)
20 SW4[7-8]="OFF OFF" (enable serial ports,I'm using the top serial connector)
21 SW22[1-4]="OFF OFF ON OFF"
22 SW5[1-10[="ON ON OFF OFF OFF OFF OFF OFF OFF OFF"
23 J1 = "Enable Prog" (Make sure your flash is programmable for development)
25 1.2 If you want to test PCI functionality with a 33Mhz PCI card, you will
26 have to change the system clock from the default 66Mhz to 33Mhz by
27 setting SW15[1]="OFF" and SW17[8]="OFF". After that you may also need
28 double your platform clock(SW6) because the system clock is now only
29 half of its original value.
31 1.3 SW6 is a very important switch, it decides your platform clock and CPU
32 clock based on the on-board system clock(default 66MHz). Check the
33 document along with your board for details.
36 2. MEMORY MAP TO WORK WITH LINUX KERNEL
38 2.1. For the initial bringup, we adopted a consistent memory scheme
39 between u-boot and linux kernel, you can customize it based on your
42 0x0000_0000 0x7fff_ffff DDR 2G
43 0x8000_0000 0x9fff_ffff PCI MEM 512M
44 0xc000_0000 0xdfff_ffff Rapid IO 512M
45 0xe000_0000 0xe000_ffff CCSR 1M
46 0xe200_0000 0xe2ff_ffff PCI IO 16M
47 0xf000_0000 0xf7ff_ffff SDRAM 128M
48 0xf800_0000 0xf80f_ffff BCSR 1M
49 0xff00_0000 0xffff_ffff FLASH (boot bank) 16M
51 2.2 We are submitting Linux kernel patches for MPC8540 and MPC8560. You
52 can download them from linuxppc-2.4 public source. Please make sure the
53 kernel's ppcboot.h is consistent with U-Boot's u-boot.h. You can use two
54 default configuration files as your starting points to configure the
56 arch/ppc/configs/mpc8540_ads_defconfig
57 arch/ppc/configs/mpc8560_ads_defconfig
60 3. DEFINITIONS AND COMPILATION
62 3.1 Explanation on NEW definitions in include/configs/MPC8540ADS.h and include/
64 CONFIG_BOOKE BOOKE(e.g. Motorola MPC85xx, IBM 440, etc)
65 CONFIG_E500 BOOKE e500 family(Motorola)
66 CONFIG_MPC85xx MPC8540,MPC8560 and their derivatives
67 CONFIG_MPC8540 MPC8540 specific
68 CONFIG_MPC8560 MPC8560 specific
69 CONFIG_MPC8540ADS MPC8540ADS board specific
70 CONFIG_MPC8560ADS MPC8560ADS board specific
71 CONFIG_TSEC_ENET Use on-chip 10/100/1000 ethernet for networking
72 CONFIG_SPD_EEPROM Use SPD EEPROM for DDR auto configuration, you can also
73 manual config the DDR after undef this definition.
74 CONFIG_DDR_ECC only for ECC DDR module
75 CONFIG_DDR_DLL DLL fix on some ADS boards needed for more stability.
76 CONFIG_RAM_AS_FLASH after define this, you can load U-Boot into localbus
77 SDRAM and treat localbus SDRAM as a flash. We use this
78 memory based U-Boot before flash is working while Metrowerks
79 and Windriver are still working on their flash/JTAG tools.
80 if you can program the flash directly, undef this.
81 Other than the above definitions, the rest in the config files are straightforward.
84 export CROSS_COMPILE=your-cross-compile-prefix(assuming you're using BASH shell)
87 make MPC8560ADS_config (or make MPC8540ADS_config)
93 4.1 When connecting with kermit, the following commands must be present.in
94 your .kermrc file. These are especially important when booting as
95 MPC8560, as the serial console will not work without them:
100 set flow-control none
103 4.2 Sometimes after U-Boot is up, the 'tftp' won't work well with TSEC ethernet. If that
104 happens, you can try the following steps to make network work:
105 MPC8560ADS>tftp 1000000 pImage
106 (if it hangs, use Ctrl-C to quit)
107 MPC8560ADS>nm fdf24524
110 >. (to quit this memory operation)
111 MPC8560ADS>tftp 1000000 pImage
113 4.3 If you're one of the early developers using the Rev1 8540/8560 chips, please use U-Boot
114 1.0.0, as the newer silicon will only support Rev2 and future revisions of 8540/8560.
116 4.4 Reflash U-boot Image using U-boot
119 => protect off fff80000 ffffffff
120 => erase fff80000 ffffffff
121 => cp.b 0 fff80000 80000
