examples/basic/sdtest.py doesn't work on my picovision

[cutecprog]

I get this error when I try to run this on my picovision.

Traceback (most recent call last):
File "<stdin>", line 11, in <module>
OSError: [Errno 19] ENODEV

Mostly just trying to figure out how to use an sdcard in micropython. I'm not super knowable in this area and any help would be appreciated.

What kind of SD card are you using?

You could try formatting it as FAT32 and see if that gets it talking? There's some instructions how to do that here: https://learn.pimoroni.com/article/getting-started-with-picovision#how-to-play-doom

I think MicroPython also throws a (not very descriptive) error if you try to mount an SD card twice without unmounting it - so it could be worth trying an os.umount("/sd") or resetting the board and running the example again?

Thank you for responding. Started by trying os.umount("/sd") before mounting which gave me the error OSError: [Errno 22] EINVAL. I formatted the SD card as fat32 with gparted previously. But to be sure I used the raspberry pi imager as outlined in the doom installation you linked. And that worked! I'll chalk this up to not understanding gparted.
