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' (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. For example, if at 66MHz your system
30 clock showed SW6[0:1] = 01, then at 33MHz SW6[0:1] it should be 10.
32 1.3 SW6 is a very important switch, it decides your platform clock and CPU
33 clock based on the on-board system clock(default 66MHz). Check the
34 document along with your board for details.
37 2. MEMORY MAP TO WORK WITH LINUX KERNEL
39 2.1. For the initial bringup, we adopted a consistent memory scheme
40 between u-boot and linux kernel, you can customize it based on your
43 0x0000_0000 0x7fff_ffff DDR 2G
44 0x8000_0000 0x9fff_ffff PCI MEM 512M
45 0xc000_0000 0xdfff_ffff Rapid IO 512M
46 0xe000_0000 0xe00f_ffff CCSR 1M
47 0xe200_0000 0xe2ff_ffff PCI IO 16M
48 0xf000_0000 0xf7ff_ffff SDRAM 128M
49 0xf800_0000 0xf80f_ffff BCSR 1M
50 0xff00_0000 0xffff_ffff FLASH (boot bank) 16M
52 2.2 We are submitting Linux kernel patches for MPC8540 and MPC8560. You
53 can download them from linuxppc-2.4 public source. Please make sure the
54 kernel's ppcboot.h is consistent with U-Boot's u-boot.h. You can use two
55 default configuration files as your starting points to configure the
57 arch/ppc/configs/mpc8540_ads_defconfig
58 arch/ppc/configs/mpc8560_ads_defconfig
60 3. DEFINITIONS AND COMPILATION
62 3.1 Explanation on NEW definitions in:
63 include/configs/MPC8540ADS.h
64 include/configs/MPC8560ADS.h
66 CONFIG_BOOKE BOOKE(e.g. Motorola MPC85xx, IBM 440, etc)
67 CONFIG_E500 BOOKE e500 family(Motorola)
68 CONFIG_MPC85xx MPC8540,MPC8560 and their derivatives
69 CONFIG_MPC8540 MPC8540 specific
70 CONFIG_MPC8560 MPC8560 specific
71 CONFIG_MPC8540ADS MPC8540ADS board specific
72 CONFIG_MPC8560ADS MPC8560ADS board specific
73 CONFIG_TSEC_ENET Use on-chip 10/100/1000 ethernet for networking
74 CONFIG_SPD_EEPROM Use SPD EEPROM for DDR auto configuration, you can
75 also manual config the DDR after undef this
77 CONFIG_DDR_ECC only for ECC DDR module
78 CONFIG_DDR_DLL DLL fix on some ADS boards needed for more
80 CONFIG_RAM_AS_FLASH after define this, you can load U-Boot into
81 localbus SDRAM and treat localbus SDRAM as a
82 flash. We use this memory based U-Boot
83 before flash is working while Metrowerks and
84 Windriver are still working on their
85 flash/JTAG tools. if you can program the
86 flash directly, undef this.
88 Other than the above definitions, the rest in the config files are
94 Assuming you're using BASH shell:
96 export CROSS_COMPILE=your-cross-compile-prefix
99 make MPC8560ADS_config (or make MPC8540ADS_config)
104 4.1 When connecting with kermit, the following commands must be present.in
105 your .kermrc file. These are especially important when booting as
106 MPC8560, as the serial console will not work without them:
109 set carrier-watch off
111 set flow-control none
115 4.2 Sometimes after U-Boot is up, the 'tftp' won't work well with TSEC
116 ethernet. If that happens, you can try the following steps to make
119 MPC8560ADS>tftp 1000000 pImage
120 (if it hangs, use Ctrl-C to quit)
121 MPC8560ADS>nm fdf24524
124 >. (to quit this memory operation)
125 MPC8560ADS>tftp 1000000 pImage
127 4.3 If you're one of the early developers using the Rev1 8540/8560 chips,
128 please use U-Boot 1.0.0, as the newer silicon will only support Rev2
129 and future revisions of 8540/8560.
132 4.4 Reflash U-boot Image using U-boot
135 => protect off fff80000 ffffffff
136 => erase fff80000 ffffffff
137 => cp.b 0 fff80000 80000
140 4.5 Reflash U-Boot with a BDI-2000
142 BDI> erase 0xFFF80000 0x2000 0x40
143 BDI> prog 0xfff80000 u-boot.bin.8560ads
