Board startup help

Question asked by tommmee on Jul 24, 2013

I have a custom PCB using the ADuCM360 that I am having difficulty getting started.  I am trying to connect using a J-Link debugger without success.  The debugger is able to recognize there is an SWD connection, but cannot detect a device.  The relevant messages displayed are:

 

Info: Found SWD-DP with ID 0x2BA01477
No device found on SWD.

 

It also attempts to halt the processor, although I don't think it succeeds, as it takes several seconds and all the register values displayed are 0.

 

I am able to connect the same debugger to the ADI eval board with no problems, so it is likely a problem with my board.  The voltages and RESET signal or OK, and it doesn't seem like much else is required to connect the debugger.

 

Anyone have any ideas on how I can track down the problem?

 

Thanks,

 

Tom
