I was following this thread because i couldn’t get the FAT32 format to work on a SD card which has more storage than 32GB.
I first tried to create a 32GB partition and leave the rest empty, but the Proffie (3.9) board was unable to mount the SD card.
I tried using the SD association formatter, as suggested above, but this resulted in an exFAT format. Maybe I’m just blind, but i couldn’t find a format selection box or something.
What worked for me was the application Rufus:
- Select your SD card as the device
- Set “Boot selection” to Non bootable
- Change the file system to FAT32
- Hit Start
Now I have a 128GB SD card which is FAT32 formatted and readable/mountable by the board!
Hope this helps anyone with the same problem
