Configuration of SDMMC peripheral in CubeMX

[Hueli.1]

I am trying to connect to the WFM200 wifi module over SDIO. I am using the SDMM peripheral library/code for this.

However, in the selection in CubeMX there is only the options for SD and MMC but no SDIO.

Which option should I choose for using SDIO with the WFM200?

Hello @Hueli.1​,

Here is an example to configure SDIO. You may need to increase the SDIOCLK divide factor if getting FR_DISK_ERROR

Hope this helps!

thank you for the answer.

I now went with low gpio speed also to reduce noise in the signal since I am using a nucleo allowing only speeds up to ca 400kHz without distorision:
