The author of Marlin firmware has integrated numerous motherboards, and configuration files into their releases. It would help the PandaPi users if you worked with them so that any updates to Marlin could immediately benefit your users.
As it is currently, the process and tool chain required to update anything beyond the config files is well beyond my capabilities. I don't have a dedicated Linux machine to attempt the compiles.
I'm still using a PandaPi v2.5 and continue to hope a version 3 board will be released that has upgradeable firmware, and the the CAN bus built in. Few of the upgrades work with my outdated v2.5 board.
Mark, will this be updated at some point? Marlin has made many improvements since this was released and is at 2.0.9.2, while this goes back to 2.0.6.
