The eMMC on the EVB works well. However, I can't get any sd card to work with this MCU.

The signals used by the SDIO (J32 connector) are also used by the eMMC. Should I remove these resistors to get the SD working?

Hi @paulM90 ,

 

Thanks for your interest in NXP IMX RT series. I'd like to provide service.

There are some very useful example projects in the SDK that you can download here:https://mcuxpresso.nxp.com/en/dashboard?uvid=547076

sdcard_polling is well worth trying out, and in the ReadMe for this project, it mentions that some preparation of the hardware needs to be done.

Hope it helps!

Best regards,

Gavin
