MS: Cannot initialize the SD card: MS: Card is unusable, try another one
FS: Can’t open 0:/data to write, error code 12
FS: Attempt to write string to a non-open file.
FS: Attempt to close a non-open file.
Trying to use DataLogger_dif. Builds and loads fine but this is the error that I get. I’ve re-formatted the card per the tool specified on your forum. But still doesn’t work. Help please.
