Can't read onboard SD card on SKR 1.3

[Dendrowen]

I am unable to read the SD card in the SKR 1.3 from the TFT. It says:

Loading....
Read SD card error!

How can I solve this in the marlin firmware?

I guess it's because the SD card isn't initialized on start. I'm using both the TFT35 and the Smart controller LCD, but I just print from the Smart controller LCD because I have the init SD from that LCD, to mount the SD which is placed in the SKR 1.3.

hello
@xoniq could you post what you change on marlin cfg in order to be able to print from On board SD card

i have the same feeling as you about the stability of printing from TFT35 SD card

Hi @melufre

Here are my current config files:

The card is initialized because I can see it from my PC. Not from the TFT though. It doesn't matter if the PC is connected or not.

If you can see it on the PC, it means the PC mounts the card, not the board itself. With no PC attached and only a screen, I have to manually mount it.

And how can I achieve that?

Make sure you have enabled that Marlin should use on-board SD by default.

I think the BAUDRATE has to be at 115200

so

#define BAUDRATE 115200

then it should work. But better confirm the firmware has been written/changed.
