Warning-Unknown break cause !!!

[ssk]

Posted on April 17, 2015 at 10:55

Hello,

I am trying to execute a simple serial driver application on my target board. It uses SPC560D30L3 MCU. I have tested the same code using SPC Discovery kit (SPC560D30L3) mounted on it. The code executes successfully on Discovery kit but fails to execute on actual target hardware. When debugged, it displays following warning,

''Warning, Core::PpcJtagTargIntf, Unknown break cause !!!''

It hangs inside the function 'componentsinit' giving above warning. What could be wrong? Is any other configuration required for MCU or for debugger? I am using SPC5-UDESTK debugger here.

Thanks in advance for your any help.

Mike.

Hello Mike ,

it is a data Abort.

You should go step-by-step to check what is the issue.

often , you try to access to ''forbidden'' registers.

Are you using a oroginal Application Wizard demo ?
