| 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:-) |
