Sorry, to be clear, I meant 8 sectors per cluster. I also thought of something else, there is a problem with sd card lib & jalv2.4o beta but I guess you know that already. See these lines in sd_card lib: --for jalv2 2.40 ;var volatile byte sd_sector_buffer_low[256] -- 256 low bytes ;var volatile byte sd_sector_buffer_high[256] -- 256 high bytes -- --for jalv2 2.4n var byte sd_sector_buffer_low[256] -- 256 low bytes var byte sd_sector_buffer_high[256] -- 256 high bytes
I'm happy to see your interest. Have you tried the other fat32 lib/ sample as well? If you are planning to make a board you may also want to put a 23k256 for the large fat32 lib. Otherwise you are limited to a few hundred files per directory depending on ram space available. 23k256 costs just over $1 I'll test and update my files with your changes. Thanks for your work on these much needed recent changes! Matt. On Apr 20, 6:42 am, mattschinkel <[email protected]> wrote: > It could possibly be the cluster size.
