Can't burn image eMMc

[Tinker Board]

Hi all,

I am having the same problem as a topicstarter.
I have a Board S, jumper is in parking mode, when I connecting the board to PC with a cable, I see no new drives at all. Earlier I was able to write the image to the board - can it be done only once, or am I doing something wrong?

If I want to rewrite board from scratch, how can I do it?

Tnx

Hi DVE,

That would depends on what image inside your Tinker Board S' eMMC.
Usually, the newer TinkerOS & Armbian, etc. All should support the UMS function (mount as a drive on PC though USB).

Otherwise, you can take reference here.

Or, if currently your Tinker Board S still can boot in OS (Linux).
You can just dd part of new image to replace U-Boot and enable UMS function.

e.g. Spite U-Boot part from image and dd to eMMC.

Code:

sudo dd if=20180622-tinker-board-linaro-stretch-alip-v2.0.7.img of=/dev/mmcblk1 skip=64 seek=64 bs=512 count=8128

// skip=N skip N ibs-sized blocks at start of input
// seek=N skip N obs-sized blocks at start of output
