12.3 XPS_HWICAP - How do I read the WBSTAR register from the ICAP

Description

How do I use the XPS_HWICAP core after a warm boot to find out which bitstream was loaded when using MultiBoot?

Solution

The XAPP1100 application notes show how to use the ICAP MultiBoot in Virtex-5 (this is still valid for Virtex-6). 

There is also example C-code to read this register and other configuration registers from the ICAP.

The example code is found in the following location:
