Hi all,
I'm working on a self reconfigurating system on ml402 (a virtex 4 sx35
device). I tested all bitstreams, full and partial, and they work
fine. The problems come when I try to make a self reconfiguration
loading bitstreams stored in CF. I successfully generated the
system.ace file and I put it on the CF with a partial bitstream. I set
the M2:M0 pin to 111 and the selector to SYSACE (also the persist bit
option is set correctly). When I turn on the board it loads the
system.ace file and configure the system that works fine. The done led
is turned on, but also the error led is turned on and the system can't
open the partial bitstream from CF. I tried to put some other types of
files on CF and make a C code to open and read them, but the result is
the same: done led turned on (system configured), and error led turned
on. Through serial the program says me that it can't open files
because it can't find them.
Has anyone any suggestion? Has anyone successfully reconfigured a
virtex device through hwicap and CF?
I'd really appreciate your help. Thanks.
