General Description:
Can I use only one PowerPC if I have a dual-PowerPC EDK system?

Solution

Please see (Xilinx Answer 4582) for information on wiring up a JTAG chain in a multi-processor Virtex-II Pro (2VP20 or greater).

Once you have wired up your hardware, you will need to add source files for both the used and unused processor. This is a current limitation of the EDK and will be fixed in future releases.

An example of some dummy code you could add for the unused PowerPC:

void main(void)
{
while(1);
}
