Dear Heiko,

How the feed back line is organized? I mean how host system will know that a) we done flash correctly? b) the booted image is bad or good?
For both questions the answer is, that you need to write a testcase which answer this question.
For a) you flash the image in some way through U-Boot commands. You start this commands from a tbot testcase written in python and parse the output and/or return code of the command and than decide ...
Same for b) reboot the board, check if new version is installed by parsing the U-Boot bootlog, than start U-Boot commands to find out, if current installed version is good or bad.
Maybe it would be nice for people who don't know tbot if you could link to some examples for such testcases? I think this should even be covered in the tbot docs?
Best regards,
