Built in self test


I have made changes to the firmware and uploaded them onto the H7. The camera seems to be stuck on the self test I see no blue light flashing? How long should it take?. Also is it possible to see the output of print statements in the firmware for debugging purposes.

Hi, yes, you can add printf().

As for why the firmware is broken… well, if you changed things… then it would help to know what changed. However, we general don’t offer help support except for very specific questions with the firmware. If you are editing the firmware we expect you know what you are doing.


Yes thats fine once i have the use of the print statement I will probably figure it out myself. Cheers.
