11 EDK - I cannot connect to the processor on my ML40x board. Why?

Description

I cannot connect to the processor on my ML40x board. Why?

Solution

A problem was introduced to Base System Builder (BSB) in version 11 of EDK where BSB erroneously assigns the USRCLK signal as the system signal instead of SYSCLK. A change to the EDK project's UCF file can work around the problem:

ML401, ML402, ML403 - Change AD12 to AE14

ML405 - Change AB12 to AB14

This problem has been fixed in EDK 11.4, available at:
