No SDIO option in Cube IDE

[sanfran]

Hi

I am using nucleo-u5a5zj-q board. MCU is stm32u5a5zjt6qu,

In cube IDE, i saw SDMMC included but no SDIO driver.

May I please know where I could download it?

Thanks for the help.

They changed the peripheral name from SDIO to SDMMC, and then there are code libraries dealing with SD (cards) and MMC (eMMC chips)

Review Reference Manual coverage of the peripheral

I would like to bring up a sdio card instead of sd. Sdio has their own particular cmd and need to provide by HAL.

So a WiFi card or something? Please be a bit more specific.

Assume whatever "SDIO" functionality you have will need to be ported into the SDMMC peripheral model. Figure which is the shortest path

Hi Tesla,

Yes, it is a Wi-Fi card. 

Thanks for these paths. I will check if cmd5, cmd52 and cmd53 arre supported by these files.

Thanks
