1 After several heart-struck failure, I got one workable way to program
2 each other in FLASH between PlanetCore and U-Boot.
4 Hardware Platform : RPXlite DW(EP 823 H1 DW)

48 2. From PlanetCore to U-Boot
50 Utilities : PlanetCore FLASH Burner - PCB200.mot
52 Use Flash Burner to finish the work:
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,
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:-)
