# Porting U-Boot onto RPXClassic LF_BW31 board
# Written by Pierre AUBERT
# E-Mail p.aubert@staubli.com
# Stäubli Faverges - <www.staubli.com>
#
# Sept. 20 2001
#
# Cross compile: Montavista Hardhat ported on HP-UX 10.20
#
Flash memories : AM29DL323B (2 banks flash memories) 16 Mb from 0xff000000
DRAM : 16 Mb from 0
NVRAM : 512 kb from 0xfa000000
- environment is stored in NVRAM
- Mac address is read from EEPROM
- ethernet on SCC1 or fast ethernet on FEC are running (depending on the
configuration flag CONFIG_FEC_ENET)

# Porting U-Boot onto RPXlite board
# Written by Yoo. Jonghoon
# E-Mail : yooth@ipone.co.kr
# IP ONE Inc.
# Since 2001. 1. 29
# Shell : bash
# Cross-compile tools : Montavista Hardhat
# Debugging tools : Windriver VisionProbe (PowerPC BDM)
# ppcboot ver. : ppcboot-0.8.1
###############################################################
# 1. Hardware setting
###############################################################
1.1. Board, BDM settings
Install board, BDM, connect each other
1.2. Save Register value
Boot with board-on monitor program and save the
register values with BDM.
1.3. Configure flash programmer
Check flash memory area in the memory map.
0xFFC00000 - 0xFFFFFFFF
Boot monitor program is at
0xFFF00000
You can program on-board flash memory with VisionClick
flash programmer. Set the target flash device as:
29DL800B
(?) The flash memory device in the board *is* 29LV800B,
but I cannot program it with '29LV800B' option.
(in VisionClick flash programming tools)
I don't know why...
1.4. Save boot monitor program *IMPORTANT*
Upload boot monitor program from board to file.
boot monitor program starts at 0xFFF00000
1.5. Test flash memory programming
Try to erase boot program in the flash memory,
and re-write them.
*WARNING* YOU MUST SAVE BOOT PROGRAM TO FILE
BEFORE ERASING FLASH
###############################################################
# 2. U-Boot setting
###############################################################
2.1. Download U-Boot tarball at
ftp://ftp.denx.de
(The latest version is ppcboot-0.8.1.tar.bz2)
To extract the archive use the following syntax :
> bzip2 -cd ppcboot-0.8.1.tar.bz2 | tar xf -
2.2. Add the following lines in '.profile'
export PATH=$PATH:/opt/hardhat/devkit/ppc/8xx/bin
2.3. Make board specific config, for example:
> cd ppcboot-0.8.1
> make TQM860L_config
Now we can build ppcboot bin files.
After make all, you must see these files in your
ppcboot root directory.
ppcboot
ppcboot.bin
ppcboot.srec
ppcboot.map
2.4. Make your own board directory into the
ppcboot-0.8.1/board
and make your board-specific files here.
For exmanple, tqm8xx files are composed of
.depend : Nothing
Makefile : To make config file
config.mk : Sets base address
flash.c : Flash memory control files
ppcboot.lds : linker(ld) script? (I don't know this yet)
tqm8xx.c : DRAM control and board check routines
And, add your board config lines in the
ppcboot-0.8.1/Makefile
Finally, add config_(your board).h file in the
ppcboot-0.8.1/include/
I've made board/rpxlite directory, and just copied
tqm8xx settings for now.
Rebuild ppcboot for rpxlite board:
> make rpxlite_config
> make
###############################################################
# 3. U-Boot porting
###############################################################
3.1. My RPXlite files are based on tqm8xx board files.
> cd board
> cp -r tqm8xx RPXLITE
> cd RPXLITE
> mv tqm8xx.c RPXLITE.c
> cd ../../include
> cp config_tqm8xx.h config_RPXLITE.h
3.2. Modified files are:
board/RPXLITE/RPXLITE.c /* DRAM-related routines */
board/RPXLITE/flash.c /* flash-related routines */
board/RPXLITE/config.mk /* set text base address */
arch/powerpc/cpu/mpc8xx/serial.c /* board specific register setting */
include/config_RPXLITE.h /* board specific registers */
See 'reg_config.txt' for register values in detail.

After several heart-struck failure, I got one workable way to program
each other in FLASH between PlanetCore and U-Boot.
Hardware Platform : RPXlite DW(EP 823 H1 DW)
1. From U-Boot to PlanetCore

2. From PlanetCore to U-Boot
Utilities : PlanetCore FLASH Burner - PCB200.mot
Use Flash Burner to finish the work:
First, TFTP the U-Boot image file to RAM; For example,
RPXlite_DW.bin to 0x400000
Second, TFTP FLASH Burner to RAM; For example,
0x100000
Third, run the FLASH Burner and Program the U-Boot
image into the correct location in FLASH.

Well, sometimes network function of PlanetCore couldn't work when
switching from U-Boot to PlanetCore. For example, you couldn't
download a file from HOST PC via TFTP. Don't worry, just restart your
HOST PC and everything would work as smooth as clockwork. I don't
know the reason WHY:-)
