Hi all, I'm working on a dynamically reconfigurable project on ML402 (virtex-4 sx35) and, for this, I have to load partial bitstreams from a Compact Flash. I successfully generated a system.ace file that works fine and configure my fpga at turn on. The problems come when I try to load a partial bitstream stored on the CF: it always isn't possible and the error led turn on. The first time I try to open bitstream the program stalls, the second time it says that it can't open the file. Always so. I tried to open and read an image .bmp, using sysace_fopen and sysace_fread, and it works. The problem comes with bitstreams (both .bit and .bin). I have this problem both in my reconfigurable system and in a normal system based on MicroBlaze.
Have you any suggestion? I would be grateful for your help.
