Did you try to read the CF in anodher system (linux or windows) ?
Does this error also occour with an CF formatted from linux or windows ?
Do you use the fatfs from CVS or some newer version (I posted some
patches on ecos-patches list) ?
Can you provide a test case in form of a small program wich creates and
deletes a file ?
Alternatively if you send me the trace output I'll check it.
