[partial-reconfig] CRC-Error when writing partial bitstreams to ICAP

[Andreas Hofmann <ahofmann@xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx>]

Hello,

I'm currently porting the audio_design example from Xilinx to the ML405
board without much success. I have followed the PR_V4_app_note.pdf as
closely as possible targeting the Virtex4FX20/ML405 instead of the
original LX25 device. As I'm still waiting for the new ISE/EDK software
version to arrive, I'm using ISE/EDK 8.1_PR8 with hwicap 1.10.a taken
from the EDK 9.1.02 Service Pack.

A static implementation of the design works ok. But I have had no
success with reconfiguration.

The dynamic reconfigurable full bitstream works but when writing the
partial bitstreams that I have created to the device a CRC error occurs
and therefore no reconfiguration takes place. When writing the partial
bitstreams to the device using iMPACT the FPGA does a proper
reconfiguration.

Reading the IDCODE of the device and the STAT register via the ICAP
succeeds.

What can I do to investigate this further?

Best regards,

Andreas
