SDCard on STM32F7-Disco

Hello,

I'm trying to make the SD card work on the board STM32F7-Disco. Is the support for SDCard implemented on this board?

I formatted a 8GB µSDcard in FAT32, plugged it in the µSD slot of the board and issued a soft reset (CTRL+D).

The following message is printed on the REPL :

Code: Select all

PYB: sync filesystems
PYB: soft reboot
PYB: can't mount SD card
MicroPython v1.8.5-117-g3ccdbf7-dirty on 2016-11-05; F7DISC with STM32F746
Type "help()" for more information.
It seems that it detects the SDcard, but cannot mount it. Any idea why?

Thanks!

I seem to recall that there might be some DMA issues related to that.

Looks like its still open.
