SystemACE problem |
|
|
Hi,
As a student I'm working on a project which requires us to read a file from
a Compact Flash card using the Xilinx SystemACE controller on the XUP V2P
developement boards. Because of a bug in our program it ended up in an
endless loop, so it never got to the fclose() statement. Now it seamed that
the whole CompactFlash filesystem had gone corrupted by this. Now I have
tryed many different methods of formatting the Compact Flash card (even used
mkdos fs, with its needed arguments) and the card works on any compact flash
card reader for pc but for some reason the xup board doesn't want to read
from the compact flash card anymore.
Has anyone of you encountered that same problem, or maybe knows a solution
to this problem?
thanks in advance for your help

checkl first that the systemACE works |
buy a new CF card
format with FAT16
copy a good known .ACE into the root dir
insert card
check if the FPGA gets configured,
then proceed with next steps..

Thanks for your fast anwer, but have tried an other CF card and then it
worked again, untill we came up with a similar loop problem in our code, and
the file system was corrupted again.
Btw, at this moment We're not using the CF card to configure our device,
just as a medium were we can read some data (.jpg in our case)
Greets,
