ARM exception information

[juanc]

Hi can someone explain to me what are the 3 hex numbers following an Arm exception on TMT ?
The 1
the 105f7b4
and the a0000 ?

Arm exception 1 105f7b4 a0000

How can I know wich part of my code generated the exception ?

Thanks.

Arm exception 1 105f7b4 a0000

I’ve just had Arm exception 1 1082984 900

I found the following FAQ entry:

@FAQ

‘ARM exception 1 XXX’ is received in case of illegal RAM access by the embedded application. Here, XXX is the address the application was trying to access. This can occur due to invalid pointer operation by the Open-AT embedded application.
The embedded application can also give ARM exception on a firmware if the firmware is a B memory (32 bit memory) product and the application is compiled for A memory product (by giving compiler option -16). Since a memory location defined for “A” memory product might become a protected memory location for the “B” memory product, this error can occur.
See: wavecom.com/modules/movie/sc … ame=Errors

Unfortunately, that doesn’t match the actual format of the message we’ve seen!

The Basic Development Guide only mentions the same format

So what do the parameters actually mean??

The Basic Development Guide adds:

If the symbol file is correctly configured in the Target Monitoring Tool (see document [Ref 1]), then a Back Trace must describe the affected ‘C’ functions…

[Ref 1] is the Tools Manual

I think this question can be answered by wavecom only — but I’m waiting for three months for an answer now
