Hello. I am testing my own board with STM32H743.
As the title suggests, DMA needs to be enabled.
If don't using DMA, you can write SD card normally.
If use DMA Enable, f_open will wait 30 seconds (just like the timeout setting) and will fail with an Error 1 output.
While we looked at the preceding questions from the ST community,
I need your advice to see if I am a beginner.
Thank you.
