In the DevKit Carried Board, there is SDMMC interface(that be called “SDMMC3_HV” in the pinmux excel file). is connect to the M.2 E Key’s sdio interface.
We’ve design a Carrier Board which connect a extend SD socket( for SD Card). via this SDMMC interface.
- and the SD Card Detect pin is connect to SOM’s gpio08.
Is that need to tune the device tree file or any other configuration?
If it is need, Is there any link/post/suggestion about how to configure for it??
