[avr-chat] Timeout after once successful firmware flashing

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...

Auto-detected: /dev/ttyUSB0

Uploading .pioenvs/megaatmega2560/firmware.hex
