Clarification on SD Card size limit (32Gb?)

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
