Do FatFS SDK examples actually use SDIO?

jackking — Sun, 24 Oct 2021 18:15:13 GMT

I am testing my SD Card interface, and using FatFS. It seems that the FatFS implementation only uses SD, not SDIO. Is this understanding correct?

Are there any examples of the MCUXpresso SDK using SDIO with FatFS, or any SDIO example at all?

FatFS SDK examples uses SD but not SDIO. For the moment, we don't have fatfs+sdio demo.

User can refer sdio demo under SDK folder to write own code.

Hope this helps,

I am using the IMXRT1060 SDK and I don't see any demos for simple SDIO at all.

I do see the use of SDIO for the wifi example, so I will take a look at that. Otherwise, I only see examples for SDIO in other part SDKs, such as LPC4300, but I don't know if that will be easily ported to IMXRT.

Yes, sdio demo code is not included in IMXRT1060 SDK

But we can find sdio driver code in folder {IMXRT1060 SDK}\middleware\sdmmc\sdio

Hope this will help you,
