SDMMC example for RW612 module

khalidL — Tue, 01 Jul 2025 14:12:04 GMT

The current RW612 SDK version doesn't include a startup example related to interfacing an SD card (SDMMC Example). Is there any tutorial or example that can be imported from other project to implement an SD file system using the RW612 module?

We appreciate your help and time.

Hi,

The RW612 SDIO interface can only work in slave mode.

Regards,

Daniel.

Hi Daniel,

Thank you for your quick reply, I though so, since there was no related info for host configuration in the Datasheet, but the UBLOX dev board (IRIS-W101) using the RW612 are connecting an SD Card to this bus!!!!.

Hi,

I'm sorry for the inconvenience.

I looked at the datasheet of the EVK-IRIS-W1 and in page 15, it states the following SDIO information "SDIO as peripheral only".

The SDIO can be used for the NCP application using another MCU or MPU as host. For instance, an i.MX RT1060 manages the application code while RW612 handles Wi-Fi, Bluetooth Low Energy, and IEEE 802.15.4 stacks. You can find more information regarding this in UM12133 and UM12095.

Regards,

Daniel.
