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
|
|
|
|
Utilities : PlanetCore Boot Loader - PCL200.mot
|
|
|
|
[root@sam tftpboot]# ppc_8xx-objcopy -O ppcboot
|
|
PCL200.mot pcl200.bin

u-boot>go 0x100000

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:-)
