Good day

Which is the correct way to use the SD Card on STM32F769DISC?

I have tried machine.SDCard, but no joy.

Hi, have you seen this video series? These are about SD card interfacing with STM32F discovery board.

@tepalia02 This is a board about MicroPython and ways to use it. Erratic comments and hints for other platforms and tools do not help art all. Please focus on the topic of this forum,

Hi @Roberthh

Can u point me in a direction how to use the SD card on the STM32F769, please?

Regards

Which board do you use? If the board has a SDCard socket, look in the schematics for the connections. If the port does not have the machine.SDCard module included, you can try using the Python SPI based SD Card driver at https://github.com/micropython/micropyt ... ers/sdcard. That one works well. It requires however that FAT file system is built into the firmware. look out in your port for vfs.VfsFat.

The 769 discovery board should work exactly the same as the Pyboard -- https://docs.micropython.org/en/latest/ ... nd-sd-card -- and if present, the SD card will be mounted automatically at boot.

If you need to work directly with the SDCard block device, then use pyb.SDCard (we haven't updated the STM32 port to use machine.SDCard yet).

Thank you @jimmo, works now
