As discussed on the list, move "arch/ppc" to "arch/powerpc" to better match the Linux directory structure. Please note that this patch also changes the "ppc" target in MAKEALL to "powerpc" to match this new infrastructure. But "ppc" is kept as an alias for now, to not break compatibility with scripts using this name.

|
|
|
|
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
|
|
|

###############################################################
|
|
|
|
3.1. 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.
