CM 3 plus SD1 interface

Fri Jul 19, 2019 12:49 am

Trying to make CM 3 plus work with a wifi module using SDIO1 interface. Could anyone confirm me that the SDIO1 interface is actually available on CM 3 plus? I checked the datasheet and there is no indication that SDIO1 is available SODIMM connector pinout.

Thanks in advance.

Did you check the Compute Module 3+ Datasheet: https://www.raspberrypi.org/documentati ... us_1p0.pdf ?

The SDIO1 is mentioned page 16 as a GPIOs alternative. You just need to add the sdio overlay on /boot/config.txt.
