SDMMC + FileX on U545

MDaniol · ‎2025-04-13

Is there any update on this issue? I have similar problem with being not able to initialize SD Card using SDMMC1 + FileX + ThreadX. Getting SDMMC_FLAG_CTIMEOUT while initialization (SD_PowerON() function). Does someone have maybe a working example of using SD Card with FileX on U545 uC?

Hi @MDaniol ,

I'm moving your post to a new thread as the old one (STM32U545 Nucleo Fails to Initialize SDMMC) was managed directly with the customer via a dedicated support channel (OLS).

You may start with this article and adapt it on your case: How to use FileX with eMMC for file system management.

That would be nice if @aroby95 can come back to provide some help here.
