Dear John,<BR>
Nice to hear from you. If possible, could you please show me your .mhs file concerning to the xps_hwicap core? Mine is listed as below:<BR>
<BR>
BEGIN xps_hwicap<BR> PARAMETER INSTANCE = xps_hwicap_0<BR> PARAMETER HW_VER = 1.00.a<BR> PARAMETER C_BASEADDR = 0x40200000<BR> PARAMETER C_HIGHADDR = 0x4020FFFF<BR> BUS_INTERFACE SPLB = plb<BR> PORT IP2INTC_Irpt = xps_hwicap_0_IP2INTC_Irpt<BR>END<BR>
<BR>
The interrupt signal is connected to the interrupt controller. <BR>
<BR>
I suspect that the driver in Linux doesn't support interrupt mode for this core, since I didn't find interrupt handler registration function in the source code, like "request_irq", etc.. <BR>
<BR>
I will appreciate if you can have some comments to me. <BR>
<BR>

<P class=EC_MsoNormal style="MARGIN-BOTTOM: 12pt"><FONT face=Tahoma size=1><SPAN style="FONT-SIZE: 9pt; 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>Ming</SPAN></FONT></P>
