PyPilot doesn't work after upgrade

[DjelaliTricks]

Probably no problem with the cpc5001. Can you boot older openplotter, or try the tinypilot image  to test?   This will tell you if the problem is hardware or not.

With Tinypilot (tinypilot_28062019.img), in SSH, pypilot_calibration return :

I might trie to reset and reload the Aduino Nano program ? I connected it in USB but can't understand what is writen in serial monitor betwen 300 and 9600 baud, after serial com is loosen.

Thank's,
