Hi @G3M! No in the meantime I learned:
- The keyboard is powered by
J3the sysctl UART notJ2the USB connector so you’d need to connect both or use some other workaround? - I learned about the recovery-mode sysctl firmware that boots the system when USB PD is connected, instead of depending on working keyboard firmware, so my current plan is to leave the keyboard in place and just use an external keyboard to edit the firmware. Or use the Pocket to “tether” another computer and flash the keyboard firmware remotely.
