2each other in FLASH between PlanetCore and U-Boot.

52Use Flash Burner to finish the work:
53
54First, TFTP the U-Boot image file to RAM; For example,
55RPXlite_DW.bin to 0x400000
56Second, TFTP FLASH Burner to RAM; For example,
570x100000
58Third, run the FLASH Burner and Program the U-Boot
59image into the correct location in FLASH.

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