SD format


#1

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.


#2

ALFAT-OEM 1.3
firmware is 1.0.8
Patriot 4GB class 4


#3

4G then we can format with FAT ?
As I know FAT is FAT16 which supports max is 2G

Some notes

  1. FAT or FAT32 should work on ALFAT, even FAT32 is supported better
  2. Try slower SD clock when initialize.
