+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:-)
