Hi,

Thanks a lot for doing that, I unfortunately overwritten the source bootloader then I found your project (after BTT refused to share their bootloader).

Unfortunately it only made it possible to boot the marlin that was already there, it does not even try to load the firmware. In addition the BED mostfet is always on (I have nothing connected there so no issue), though the stepper still moves so I guess no issue there.

I haven't gotten much time to do further debugging but i see this repo hasn't been updated for 9 months so I wonder if you managed to make it work?

So an update.

It works but not all the time, so keeping on hitting reset ends up hitting the firmware update. After managing to update again to marlin the issue with the hotbed always on is gone, so I guess this was due to a corruption of the original marlin version. So far so good.

Vs the initial version it is missing flashing the update led.

Ok so I did that last test incorrectly, the hotbed led is still on so is serial line not working, I'll try to flash my code to see if the problem is with marlin or otherwise.
