RE: [partial-reconfig] ICAP programming.

["#LUO JIANWEN#" <robin_ljw@xxxxxxxxxxxxxxxx>]

Hello LN,

I don’t think there's any modification needed to be done with the partial bitstream. See this http://www.itee.uq.edu.au/~listarch/partial-reconfig/archive/2005/03/msg00027.html

In fact, I have problems with ICAP too. After I initialize ICAP, I get nothing feedback. Can you share some experience how to establish the ICAP?
My code doesn’t work. Anything wrong?

   XStatus Status;
   XHwIcap *InstancePtr;
   Xuint32 Idcode; 

   xil_printf(" icap self test ");

   Status = XHwIcap_Initialize(InstancePtr, XPAR_OPB_HWICAP_0_DEVICE_ID, XHI_READ_DEVICEID_FROM_ICAP);
   Idcode = XHwIcap_GetConfigReg(InstancePtr, XHI_IDCODE);
   xil_printf("IDCODE is 0x%08x \n\n\r", Idcode);

Regards,
Robin

Subject: [partial-reconfig] ICAP programming.

Hello team:
I have a few questions about using ICAP for self reconfiguration.

I got a system built successfully that does partial reconfiguration,
if I were to send the bitfiles via JTAG port.

Now I would to extend this to do self-reconfiguration.
I have put the partial bitfile onto the FLASH and able to
read the file from the central processor. These bitfiles
are partial bitfiles.

Onboard ICAP is working, I was able to read the IDCODE from the
ICAP successfully.

Now to my questions.

   I tried dumping the contents of the bitfiles directly onto the
   ICAP. No processing, just read them from FLASH and write onto ICAP.
   I see no difference, infact the system hangs!!!

So, is there some processing that needs to be done onto the  partial
bitstream before sending it off to ICAP?

Any inputs, snippets of code or references to design which does it
would be greatly appreciated.

Thanks
LN
