How can I make SD cards larger than 2 GB work with the SLCD5 or SLCD5+ controllers?

The firmware in our SLCD5/SLCD5+ display modules does not support SDHC cards (those over 2 GB capacity). This is because the low-level SD card protocol changed, so even if you partition the SDHC card and create a FAT16 file system, the underlying protocol is incompatible. You will need to use a standard SD card with a capacity of 2 GB or less.
