Hi all,

Well, somebody was trying to pull the cat out of my bag. Here it is:-)

-------------------------------------------------

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 ...

Program MPC8xx PlanetCore Boot Loader v2.00 Built Sep 19, 2001 at 14:34:42 Image located from FC000000 to FC01B5D1. (Skipping an image, only loading low boot image)

Low boot board detected, skipping high boot image. Erasing, programming and verifying will start in 20 seconds Press P to start immediately or ESC to cancel Press Space or Enter for more options. ..............

Erasing Programming FLASH programmed successfully! Press R to induce a hard reset

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:-)
