I finally wrote up instructions on how to flash Printrboard firmware under Linux. https://docs.google.com/document/d/1k1LyvE4x0fVullPexstKyFFPqErNMxaygKm6nJnH1Ak/edit
Excellent write-up! Thank you for doing this to help all of us Linux users out here. One suggestion though… for the firmware, use this link instead as it will always have the latest release of the firmware (including betas).
Great comment. I will add it. The other link came from the official pb doc I think
