- 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
- [Target Operation]
- u-boot>t 100000 pcl200.bin
- u-boot>go 0x100000
- ## Starting application at 0x00100000 ...

- 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:-)
