This seems to work at providing a way to update the firmware on the Manta M8P without having to access the board itself.
What’s really interesting is that after running the first flash_can.py command, the serial device becomes visible for the second command, as you can see here:
In my printer, I have three fans attached to individual fan drivers, so to confirm that the firmware update is happening, I see the specified fan (which is different from the previous test) running after the flash_can operation.
The next steps are, partially because I’m curious but really to find the easiest overall process, is to:
- Reimage the SD Card without the Debian Fix presented above.
- Reimage the SD Card with the bash script presented here: OH NO new problem after update. I believe that this one will work and it’s simpler than the process set out in Debian Bullseye Bug causing Klipper to no longer find the printer board
- Try which of the three options (do nothing, @Sineos solution, bash script) is simplest to implement and works with the 64bit rPi OS.
I’ll report back on the results.
