i2c OLED LCD SSD1306.  Compile Marlin with Platformio , all OK , if start then show message "SD Init Fail"

If remove SD card from SD card slot , on LCD show : "Media Removed" , if insert , show "SD Init Fail".

I think you need to adjust the firmware.  Where did you purchase the OLED?

Hi. I order it on aliexpress 2.4" I2C oled lcd , working , but problem is so original Prusa lcd with sd card slot , encoder not working also . There is problem with marlin . All other (stepper motor, sensors less homing ) working good .

And this is oled , original Prusa lcd is only for sd card , encoder , etc


Firmware is problem .
