M20 Unknown command

Hello, I need to know if it is a bug or a configuration error. I have an Artillery Genius pro printer and when I enter the M20 command from the TFT it tells me "unknown command", however at the time of listing the SD files I can see and print them. SD is formatted as FAT32 and is 4Gb. I attach some data. Thank you

1- Update to bugfix-2.0.x by modifying #define SDSUPPORT and #define SDCARD_CONNECTION ONBOARD
2- Update TFT firmware

You may want to report as a bug on the Marlin GitHub.

M20 is for sdcards connected to the motherboard.

Your sd card is connected to the display (which is really a small computer) and does not uses M20 as the sdcard is not connected to the motherboard

Your M115 also clearly shows that sdcard:0 ie it is disabled.
Which is expected as you have not added hardware with a sd card as far as the controller is concerned.

I thought to load GCODE by ESP3D in the TFT SD, I would have to add an SD reader to the nodemcu module

No other devices can assess the sd card on the tft. only the tft firmware can access the sdcard on the tft

So it's not a Marlin problem. I can connect an SD reader to the printer's motherboard or a Wifi Nodemcu with ESP3d and its SD reader. Thank you
