[partial-reconfig] Linux ICAP driver runns once

[Dominik Murr <laboratum@xxxxxx>]

Hi everybody,

	I'm using John Williams' ICAP driver to reconfigure a design on a Virtex-II Pro board. I'm running a Linux kernel for PPC with a home made root filesystem (derived from MontaVista). Most everything works out as intended including the ICAP: runns, reconfigures correctly, finishes. The only flaw is that I can't use the driver twice consecutively. After one reconfiguration the second invocation of the driver would hang up the system at a certain point. 

I've tracked down the error to a call of XHwIcap_mSetRncReg which  seems to get exactly the same parameters as when called for the first iteration of the while loop. So the loop is executed once but freezes the system the second round when processing XHwIcap_mSetRncReg.

Has anybody experienced something like that?



Thanks a lot,



		Dominik
