I use stm32cubemx version 4.23. When I use SDIO 4bit and FATFS middleware, I see USE DMA Template option. If I choose 'disable', my code will run correctly. But If I I choose 'enable', I can't read and write data from uSDcard. I have some question :

1. What does this option mean?

2. What can I config (in stm32cube) to use this option?

Hi

quoc.anh

,

On CubeMX 4.24, we change the parameter Description as below (we tend to be clearer...) :

If you select ''enabled'', you should configure the DMA or else it won't work.

A thread (

https://community.st.com/0D50X00009XkWt5SAF

) could guide you in configuring DMA setttings in SDIO.

I hope it will help you.
