[BUG] SD read broken on MKS Robin Nano 1.2 (and clones) after 14 Jan 2024
Did you test the latest bugfix-2.1.x code?
Yes, and the problem still exists.
Bug Description
I've compiled successfully the 14 Jan 2024 version and is fully working. Now I'm still able to compile the last bugfix, but on Kingroon KP3S (Pro and S1), KP5L machines and other Robin Nano 1.2 machines the onboard microSD reader doesn't work anymore. I can see file list, I choose one and the print doesn't start. When I go back in the file list the filenames are 8.3 characters and no folders are read.
It prints from Octoprint.
Bug Timeline
New one
Expected behavior
Read files and print them.
Actual behavior
Read file but doesn't print. Going back to file list the directory structure is broken.

Additional information & file uploads
Same problem here. Read fails under random conditions. Reverting to mks firmware has no issue. Marlin.zip
Same here with the current 2.1.x bugfix version. Haven't tried the stable ones
Same here on Elegoo Neptune 2s with ZNP robon nano V1.3 Issue appears on release 2.1.2.2, realease 2.1.2.3, and current bugfix branch. In my case the printer sometimes does random travels or reboots in the middle of the print. Only when printing from SDCards. Tried multiple SDCards, same issue every time. Works fine when printing via OctoPrint. IT also works just fine when i enable TFT_LVGL_UI
Same here on MKS Robin Nano V3.1 with bugfix-2.1.x at ad60cdd03067877bfa453a0b18b2dd044802b55e.
I'm no longer able to print from the SD, Marlin crashes right after homing
