Hi Guys,

Could you please tell me how to write firmware code for testing SDCARD. Below are the few queries.

  • The firmware code to check the SD card interface of AM335x processor is working or not.
  • The 4 bit data lines are provided or not.
  • whenever SD card is inserted or ejected, firmware code should detect it and indicate it on serial/LCD.

Please help me out.

Thanks and Regards,

Shradhanand
