Exportimage in RKDevTool - CM3S

#1

PRODUCT IN REVIEW : CM3S
PRODUCT TO REPLACE : RASPBERRY PI CM3 (OLD VERISON)

I want to make it into an image with the contents that have been set and use it for the next download. There is an exportimage button in RKDevTool, so I tried pressing it, but only an image of 0 bytes is created on the PC. I also searched the manual, but there is no information about Exportimage. Please help.

설정이 완료된 내용으로 그대로 이미지로 만들어서 다음 다운로드에 활용하고 싶습니다. RKDevTool에 exportimage 버튼이 있어 눌러 봤는데, PC에 0바이트의 이미지만 생성됩니다. 매뉴얼도 찾아보니, Exportimage에 대한 내용은 없는데, 가능한 방법에 대해 확인 바랍니다.

@Alvin can you check the Windows usage? I’ll also test from Linux side.

Here is an example to dump image under Linux.

A few explanation:

  1. Tested with CM3S on Radxa CM3S IO Board.
  2. The current system image will boot into Loader mode when the device is powered on with micro USB cable connected to a computer.
  3. ReadLBA command uses sector (512 bytes) as unit instead of byte. This is why the final image has a size of 512 bytes per sector * SectorLen 1024 = 512 KiB.
