0. Toolchain |
|
||||||
|
|
||||||
The Binutils in current ELDK toolchain will not support MPC85xx |
|
||||||
chip. You need to use binutils-2.14.tar.bz2 (or newer) from |
|
||||||
http://ftp.gnu.org/gnu/binutils. |
|
||||||
|
|
||||||
The 8540/8560 ADS code base is known to compile using: |
|
||||||
gcc (GCC) 3.2.2 20030217 (Yellow Dog Linux 3.0 3.2.2-2a) |
|
||||||
|
|
||||||
|
|
||||||
1. SWITCH SETTINGS & JUMPERS |
|
||||||
|
|
||||||
1.0 Nomenclature |
|
||||||
|
|
||||||
For some reason, the HW designers describe the switch settings |
|
||||||
in terms of 0 and 1, and then map that to physical switches where |
|
||||||
the label "On" refers to logic 0 and "Off" (unlabeled) is logic 1. |
|
||||||
Luckily, we're SW types and virtual settings are handled daily. |
|
||||||
|
|
||||||
The switches for the Rev A board are numbered differently than |
|
||||||
for the Pilot board. Oh yeah. |
|
||||||
|
|
||||||
Switch bits are numbered 1 through, like, 4 6 8 or 10, but the |
|
||||||
bits may contribute to signals that are numbered based at 0, |
|
||||||
and some of those signals may be high-bit-number-0 too. Heed |
|
||||||
well the names and labels and do not get confused. |
|
||||||
|
|
||||||
"Off" == 1 |
|
||||||
"On" == 0 |
|
||||||
|
|
||||||
SW18 is switch 18 as silk-screened onto the board. |
|
||||||
SW4[8] is the bit labeled 8 on Switch 4. |
|
||||||
SW2[1:6] refers to bits labeled 1 through 6 in order on switch 2 |
|
||||||
SW3[7:1] refers to bits labeled 7 through 1 in order on switch 3 |
|
||||||
|
|
||||||
1.1 For the MPC85xxADS Pilot Board |
|
||||||
|
|
||||||
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) |
|
||||||
|
|
||||||
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. |
|
||||||
|
|
||||||
SW17[8] ------+ SW6 |
|
||||||
SW15[1] ----+ | [0:1] |
|
||||||
V V V V |
|
||||||
33MHz 1 1 1 0 |
|
||||||
66MHz 0 0 0 1 |
|
||||||
|
|
||||||
Hmmm... That SW6 setting description is incomplete but it works. |
|
||||||
|
|
||||||
|
|
||||||
1.3 For the MPC85xxADS Rev A Board |
|
||||||
|
|
||||||
As shipped, the board should be a 33MHz PCI bus with a CPU Clock |
|
||||||
rate of 825 +/- fuzz: |
|
||||||
|
|
||||||
Clocks: CPU: 825 MHz, CCB: 330 MHz, DDR: 165 MHz, LBC: 82 MHz |
|
||||||
|
|
||||||
For 33MHz PCI, the switch settings should be like this: |
|
||||||
|
|
||||||
SW18[7:1] = 0100001 = M==33 => 33MHz |
|
||||||
SW18[8] = 1 => PWD Divider == 16 |
|
||||||
SW16[1:2] = 11 => N == 16 as PWD==1 |
|
||||||
|
|
||||||
Use the magical formula: |
|
||||||
Fout (MHz) = 16 * M / N = 16 * 33 / 16 = 33 MHz |
|
||||||
|
|
||||||
SW7[1:4] = 1010 = 10 => 10 x 33 = 330 CCB Sysclk |
|
||||||
SW7[5:6] = 01 => 5:2 x 330 = 825 Core clock |
|
||||||
|
|
||||||
|
|
||||||
For 66MHz PCI, the switch settings should be like this: |
|
||||||
|
|
||||||
SW18[7:1] = 0100001 = M==33 => 33MHz |
|
||||||
SW18[8] = 0 => PWD Divider == 1 |
|
||||||
SW16[1:2] = 01 => N == 8 as PWD == 0 |
|
||||||
|
|
||||||
Use the magical formula: |
|
||||||
Fout (MHz) = 16 * M / N = 16 * 33 / 8 = 66 MHz |
|
||||||
|
|
||||||
SW7[1:4] = 0101 = 5 => 5 x 66 = 330 CCB Sysclk |
|
||||||
SW7[5:6] = 01 => 5:2 x 330 = 825 Core clock |
|
||||||
|
|
||||||
In order to use PCI-X (only in the first PCI slot. The one with |
|
||||||
the RIO connector), you need to set SW1[4] (config) to 1 (off). |
|
||||||
Also, configure the board to run PCI at 66 MHz. |
|
||||||
|
|
||||||
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/powerpc/configs/mpc8540_ads_defconfig |
|
||||||
arch/powerpc/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, AMCC 440, etc) |
|
||||||
CONFIG_E500 BOOKE e500 family(Motorola) |
|
||||||
CONFIG_MPC85xx MPC8540,MPC8560 and their derivatives |
|
||||||
CONFIG_ARCH_MPC8540 MPC8540 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_SYS_FSL_ERRATUM_DDR_MSYNC_IN DLL fix on some ADS boards needed |
|
||||||
for more stability. |
|
||||||
CONFIG_HAS_FEC If an FEC is on chip, set to 1, else 0. |
|
||||||
|
|
||||||
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 10000 u-boot.bin |
|
||||||
protect off fff80000 ffffffff |
|
||||||
erase fff80000 ffffffff |
|
||||||
cp.b 10000 fff80000 80000 |
|
||||||
|
|
||||||
|
|
||||||
4.5 Reflash U-Boot with a BDI-2000 |
|
||||||
|
|
||||||
BDI> erase 0xFFF80000 0x4000 0x20 |
|
||||||
BDI> prog 0xfff80000 u-boot.bin.8560ads |
|
||||||
BDI> verify |
