Did you send these commands (M502, M501, M500) between step 1 and 2?

[MatLeb]

I can't : the firmware reboot automatically after update (maybe I'm doing something wrong) and after this reboot it's not possible anymore to send commands.

[Erik262]

I guess that something got wrong while flashing the firmware. Did you use the precompiled hex file or you compiled it for yourself? If nothing helped, try this: https://www.youtube.com/watch?v=HahGaOTUmUw

[MatLeb]

Ok thanks ! In fact I did both (precompiled hex + compiled from sources), exactly the same result. When I flash it back to the original firmware Anycubic 1.1.7 (Marlin 1.1.0-RC8), no problem. Will try to do it from cura (I used platformIO on Mac) and check the jumper setting on the board, to see if it changes something.

[Erik262]

Okay, that's interesting. I'm also compiling it by myself on my Mac with platformio. Everything works. And you can't see any errors?

[MatLeb]

Yes, no error, only 2 small warnings during compile :

Have you ever tested an older version (Marlin 1.1.9)? https://github.com/Poket-Jony/Marlin-A4MaxPro-1.1.9

[Qbalion]

It seems that such behaviour occurs when you update while having SD card inserted. Try to put SD card out and then rebooting stops to happen.

I have the same problem. It always reboot after uploaded firmware. I used history version (e593da1c23a4759f6591826f815a504f0272e21a), it works fine. But it can't works on last version.

I tested all pre-release binaries of marlin 2.0.x. Following are work fine. v2.1.0-dev (Marlin 2.0.x).hex v2.1.1-dev (Marlin 2.0.x).hex v2.1.2-rc (Marlin 2.0.x).hex

Others can't work since v2.1.3-rc (Marlin 2.0.x).hex.

@MatLeb I found another solve solution: To enable LONG_FILENAME_HOST_SUPPORT, and disable SDCARD_SORT_ALPHA, SDCARD_RATHERRECENTFIRST. Might be the sort file function caused out of memory.

I had updated firmware to the v2.1.9-rc (Marlin 2.0.x) and printer kept rebooted after it. After I had put out SD card it booted normally. I had to format SD to make it working with printer again.
