For a project I have to work with PR. I managed to understand the ideas and I started
to implement it with PlanAhead. I successfuly generated my full and partial bitstreams.
Now I have to dymically reconfigure parts of my design, using the partial bitstream.
I was trying to perform readback a configuration first, using EDK and SDK, to get the feel with
the drivers and so. Alas, I'm not able to Configure the XPS_HWICAP.
When I use the function
retval = XHwIcap_CfgInitialize(&hwicap, &hwicap_cfg, XPAR_XPS_HWICAP_0_BASEADDR);
the retval-value is always 1 (indicating XST_FAILED).
I tried to dig in, into the driver, to locate the problem. Apparently both lines
Status = XHwIcap_GetConfigReg(InstancePtr, XHI_IDCODE, &TempDevId);
Status = XHwIcap_GetConfigReg(InstancePtr, XHI_IDCODE, &DeviceIdCode);
don't seem to return a DeviceIdCode other then 0.
Has anyone encountered this problem as well ?
FYI: I'm using the 12.1 environment on a 32-bit Linux machine
the IP core is : XPS_HWICAP_v4.00.a

You'll have better luck posting this to the Embedded Solution forum. However, for intensive debug, opening a case with Xilinx tech support is really the best way to approach, you'll be ensured a resolution.
