| 51 | |
| 52 | Use Flash Burner to finish the work: |
| 53 | |
| 54 | First, TFTP the U-Boot image file to RAM; For example, |
| 55 | RPXlite_DW.bin to 0x400000 |
| 56 | Second, TFTP FLASH Burner to RAM; For example, |
| 57 | 0x100000 |
| 58 | Third, run the FLASH Burner and Program the U-Boot |
| 59 | image into the correct location in FLASH. |

| 149 | Well, sometimes network function of PlanetCore couldn't work when |
| 150 | switching from U-Boot to PlanetCore. For example, you couldn't |
| 151 | download a file from HOST PC via TFTP. Don't worry, just restart your |
| 152 | HOST PC and everything would work as smooth as clockwork. I don't |
| 153 | know the reason WHY:-) |
