style='font-size:9.0pt;font-family:Tahoma'>Dear all,<br>
Has someone manage to use the driver for the Xilinx xps_hwicap core to
reconfigure bitstreams? I have enabled the driver in Linux configuration
(version 2.6.24 from Xilinx tree). However I failed to use it to reconfigure
bitstreams. The operations are listed as follows:<br>
<br>
# cp partial.bit /dev/icap0<br>
#<br>
<br>
No error information is shown, however the partial bitstream is not
successfully configured. I checked /proc/devices and the device
"icap" has been successfully registered with the major of 259. But in
/proc/interrupts, I didn't find any matching entry of the interrupt for icap
core. I tried to reconfigure the PR module with JTAG, and my design works well.
<br>
<br>
Any hints for this problem? Is the problem on the interrupt? Thanks so much if
someone can help me. <br>
<br>
BR<br>
