Source of Data Abort

Martin H.

Other Parts Discussed in Thread: CODECOMPOSER

Hi,

debugging with CodeComposer and XDS100v2 USB Emulator ( using Windows7 and Starterware) the programme repeatedly runs into an infinite loop that belongs to FIQHandler/AbortHandler/UndefInstHandler.

Does CodeComposer provide a mechanism to detect the source of such an exception?
For instance at what address a data abort exception has been caused?
Thank you.

Regards,
Martin

Martin,

Per your description you are probably using an ARM processor, right? If so, CCS does not have anything specific that shows the status of the core when entering an exception - however, this is documented by ARM itself on their documentation.

Please check the reference below for Cortex A8, for example:

Hope this helps,

Rafael

Hi Rafael,

I thought that this would be the answer, but I just wanted to be sure not to miss a feature.

The link is very helpful.

Thank you!
