SD card random state on Micoair H743 #4536
Description
Describe the bug
lately i am experiencing strange behaviors with sd card being read properly and different status: not ready, not recognized or with strange values. SD card (sandisk 4GB) has worked fine, formatted with sd formatter,
I tried to disable mag, baro,gps,sonar but no success. It's a random issue, on 10 times only once worked fine.
Tried also other sd card known to work, but no success.
To Reproduce
Use sd card on micoair AIO H743
Expected behavior
Be able to use sd card properly
