The DOS/FAT filesystem at SanDisk is very limited. Do a search for rdcf2 (Reentrant Dos Compatible File System). I've used it with CompactFlash with pretty good success. It supports FAT12 & FAT16 (not FAT32) but the current implementation has a size limit of 64K sectors (easily fixed). (I'm typing this from memory so reality may vary from details listed here.)
One other oops I ran into is that CompactFlash cards come from the factory formatted as hard-dives - that is they have a MBR w/ a partition table. RDCF2 does not know how to handle that so you must either provide the mapping layer or reformat the card as a Super Floppy. The latter is easily done by zeroing out the 1st hard sector with a prog like Hex Workshop or sectedit then reformatting the card (make sure it is either FAT12 or FAT16). Good luck. -Bill Knight R O SoftWare On Mon, 17 Feb 2003 23:20:58 +0100, nobo...@web.de wrote: >Hi, >mspgcc-users@lists.sourceforge.net schrieb am 17.02.03 22:52:15: >> >> Actually, for non-volatile Flash memory, I would suggest MMC technology. >> The interface is SPI and the MSP 430 can be adapted to that very easily >> (2-wire serial write).
