XilFatFS and CF...

xilfatfs on the XUP board: since I wasn't able to open in write mode more than one file each time, I tried to reformat the Compact Flash. I reformatted it with mkdosfs in FAT16 and it works perfectly for reprogramming the FPGA, but now I can't open any file in write mode (although everything seems correct in the software platform settings: write support is enabled). Does anybody has any idea why it doesn't work? Any possible solution?

I suffered greatly with this same problem. It all comes down to the format parameters. The best way is to get a copy windows 2000 and tell it to format in FAT16 at a command prompt with format.com

Solved the problem of writing a single file reformatting the compact flash with the utility accompaining the cf reader I bought... Yet, I noticed that to open multiple in writing at the same time, I must open the file and then do some work on it before opening the next. If I open all the files I need (without doing any operation on them between the fopens) and then write on them, only the first one gets opened correctly... I don't know if this is still related to the File System format or if it's just a XilFATFS problem...
