Hi Arctic

ATK ToolKit just perform raw writing to SD sectors, it runs without OS and do not use partitions

info. While MFG Tool is small linux image it expect to see SD card among its devices.

To answer your question it is necessary to know what exact manipulations you

did, so it may be recommended just to try reproduce this issue once more time.

Best regards

hi igorpadykov

Wrong choose lead to be unable to start and serial port can't print any information,how should i do with?

[igorpadykov · Accepted solution]

I think you could try to experiment with different eMMC

and find reason what is wrong. If you are using eMMC 4.41

(klm8g2fe3b-b001) which is not supported by i.MX51 (according

to documentation) you can not expect normal operation.
