After several heart-struck failure, I got one workable way to program
|
||
|
|
each other in FLASH between PlanetCore and U-Boot.

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:-)
