Hello TI,

I have TM4C123GXL Launchpad and trying to run some MMC/SD example using SPI interface.

Able to run the example with SD card but not with microSD card.

How can I make it work with microSD card ?

The code is based on this package.

C:\ti\TivaWare_C_Series-2.1.4.178\third_party\fatfs\port\mmc-dk-tm4c123g.c

Thanks for your help.

Regards,

Titus S.

The example you used is for the TM4C123 design kit. What hardware are you interfacing to the EK-TM4C123GXL Launchpad for the microSD card? Does it use the same SSI port?

Do you have a datasheet for that board? What connections did you make between this board and the Launchpad?
