Thanks. I read this manual but I didn't find how to visit CF card to get the data there. I don't mean to generate a system ACE file which can boot up the FPGA. I wonder whether microblaze can get the data in CF card after FPGA is configured and how to prepare the data in the CF card. Have you met this problem?

Regards,
YUWEI

Using impact you have to generate system ACE file and now i learned
that only Windows 95,98,or 2000 would format the flash card right, not
windows xp.
You can go thro the impact manual at the following site to check how
to generate system ACE files.

We have got a Virtex-II Multimedia Board which include CF card slot.

How to visit the files in CF cards? Can I just copy the files to the CF
card? Or have to build some described files to let SystemACE recognize
the file?

Hi,

You will need some code to run on Microblaze that
implements the FAT filesystem. At the hardware
level, you can read sectors from the CF through
the SystemACE. However, you will need to then
interpret the contents of the sectors as a FAT
formatted disk, so that you can retrieve files.

You can buy commercial libraries to do this, or
you can look around on Google to find how others
have done it. Here's an example:
