• Firmware file has to be renamed for each(!) update (*1)
• Use a card smaller than 32GB but bigger than 2GB (*2)
• Format only as “FAT32” (do NOT use “exFAT” or “NTFS”)
• Set the sector size to 4096
• Have no other files or directories on that card

*1: It only gets installed, if the filename differs from the one, which was used for the current installation.
*2: Smaller than 2GB does not support 4096byte sectors, larger than 32GB does not support FAT32. If your card is bigger, create a partition which is smaller than 32GB.
