| 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 | |

| 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:-) | |
