Keyboard/trackball stuck (boot mode)

I have the famous issue with the keyboard stuck in boot mode (blinking led). I had read all the forum and topics about it but I haven’t found a definitive solution. When I power on the DevTerm it works, but if I reboot it, the keyboard/trackball dies while blinking.

I have:

But nothing works.

An hypothesis I have read explains this issue is due to an undervoltage that in some way sets the keyboard in the boot mode.

Has any of you found a way to solve the issue definitely? Maybe by adding in the firmware a simple timeout for the booting mode?

Let me know. Thank you!

Just a shot in the dark, but try cleaning the contacts of your core/CPU board as well as ext board too, if you haven’t already.

Already done, nothing. :face_with_diagonal_mouth:
