Hi all, I'm using avrdude via PlatformIO on a Raspberry Pi 3 to flash Marlin 3D printer firmware onto a Makerbase MKS Gen L board. It is supposed to be Arduino Mega compatible. Connection is via USB cable.
I can upload the firmware fine, once. If I then try do it again it will timeout as the output attached. I can usually resolve it by unplugging/replugging the board or reboot Pi. What other steps I can do to troubleshoot? Building .pioenvs/megaatmega2560/firmware.hex Looking for upload port...
