Dear All: Does somebody
have the ICAP device driver for Virtex 4 FPGAs? John’s ICAP driver seems
to only support Virtex II/II Pro FPGAs. Besides, I have tested ICAP on Xilinx
ML310 development board that contains an XC2VP30 FPGA, and it can work
correctly. However, not all the partial bitstreams (all of them successfully
work using iMPACT tool) can be reconfigured using ICAP. Thus, I only reallocate
the partial reconfigurable block again and again to find a feasible one for
partial reconfiguration using HWICAP. Have you ever met the same problems?
Could you give me some suggestions when the opb_hwicap controller will be used?
Our partial reconfiguration operations usually fail in the
“XHwIcap_DeviceWrite()” function in “xhwicap_srp.c”
file. Here, the OS stalls and the partial reconfiguration operations cannot be
canceled. Thanks for
your kindly help : ) Best regards, Chun-Hsian |
