12864 LCD + Duet and SBC constant reboot - 3.2beta3

jay_s_uk

Enabling a 12864 LCD screen (fysetc mini) results in a constant reboot of the system whe a duet 3 mini 5+ is attached to an SBC.
The LCD is being enabled using M918 P2.
I am unable to obtain an output from M122

This is an issue I have seen reported in earlier releases. I tried briefly to reproduce it but failed. So:

Does it still reboot if you delete the menu files from the SD card?
Please do the following:

Run it so that it reboots. After that, do not do anything that causes a software reset.
Power the Duet down and remove the SD card.
Either connect via USB, power up and get a M122 report; or move the SD card to a PC, remove the M918 command from config.g, replace the SD card in the Duet, power up the Duet again, and run M122.

Please post the M122 report here.

heres an M122 I managed to capture between reboots.

Thanks, that will help me to track the problem down.
