Hi Mike,
Thank you for your hints.
The good news first: Using the gel files (which is extended with the 150MHz ... Stéphane Peter

09:32 AM Software Development: RE: Dead board

Well.
The Address 0xFFFD5684 is ARM local ROM code, so it's not surprising that you can't set a breakpoint at that... Michael Williamson
