I formatted to fat32 and I could no longer write to the card.
Active-high and spi_busy-high
I format to fat and it works.
shouldn’t fat32 work also?
it seems to effect my timing.
ALFAT-OEM 1.3
firmware is 1.0.8
Patriot 4GB class 4
4G then we can format with FAT ?
As I know FAT is FAT16 which supports max is 2G
Some notes
- FAT or FAT32 should work on ALFAT, even FAT32 is supported better
- Try slower SD clock when initialize.
