Summary: |
||||
======== |
||||
|
||||
This file contains information about the cmi board configuration. |
||||
Please see cmi_mpc5xx_config for further details. The cmi board is |
||||
a customer specific board but should work with small modifications |
||||
on every board which has a MPC5xx and either a 28F128J3A, |
||||
28F320J3A or 28F640J3A Intel flash mounted. |
||||
|
||||
Board Discription: |
||||
================== |
||||
|
||||
* Motorola MPC555 |
||||
* RS232 connection |
||||
* Intel flash 28F640J3A |
||||
* Micron SRAM 1M |
||||
* Altera PLD |
||||
|
||||
Bootstrap: |
||||
========== |
||||
|
||||
In contrast to the usual boot sequence used in U-Boot, on the |
||||
cmi board we don't boot from the external flash directly. |
||||
Because of we use a 16-bit flash and don't sample a RCW |
||||
from the data bus to set the startup buswidth to 16-bit. |
||||
Unfortunatly the default width, sampled from the default RCW |
||||
is 32-bit. For this reason we burn the proper RCW into the |
||||
internal flash shadow location and boot after power-on or |
||||
reset from the internal flash and then branch to 0x02000100 |
||||
where the U-Boot reset vector handler is located. |
||||
|
||||
Memory Map: |
||||
=========== |
||||
|
||||
Memory Map after relocation: |
||||
|
||||
0x0000 0000 CONFIG_SYS_SDRAM_BASE |
||||
: |
||||
0x000F 9FFF |
||||
: |
||||
: |
||||
0x0100 0000 CONFIG_SYS_IMMR (Internal memory map base adress) |
||||
: |
||||
0x0130 7FFF |
||||
: |
||||
: |
||||
0x0200 0000 CONFIG_SYS_FLASH_BASE |
||||
: |
||||
0x027C FFFF |
||||
: |
||||
: |
||||
0x0300 0000 PLD_BASE |
||||
|
||||
Flash Partition: |
||||
|
||||
0x0200 0000 Block 0 and 1 contain U-Boot except |
||||
: environment |
||||
: |
||||
0x0201 FFFF |
||||
0x0202 0000 Block 2 contains environment (.ppcenv) |
||||
: |
||||
0x0202 FFFF |
||||
|
||||
See README file for futher information about U-Boot relocation |
||||
and partitioning. |
||||
|
||||
Tested Features: |
||||
================ |
||||
|
||||
* U-Boot commands: go, loads, loadb, all memory features, printenv, |
||||
setenv, saveenv, protect, erase, fli, bdi, mtest, reset, version, |
||||
coninfo, help (see configuration file for available commands) |
||||
|
||||
* Blinking led to indicate boot process |
||||
|
||||
Added or Changed Files: |
