ARM Exception 1

Hi.

Sorry for my bad English.
I have one problem.
When I download my application in Wavecom module Q24AU some time (20-60 min from start application) in TMT I recieve
9631.797 Trace HWL 1 Arm exception 1 14 a
9631.797 ADS Bckt -> Unresolved symbol : 0x000AA2BD

9631.797 ADS Bckt -------> ADS BACK TRACE <-------

Arm Exception 1 mean that application attempt to write in protect area memory.

I test my code. I set TRACE at start and finish in all my function and this bug IS not in my functions.
I use Q24AU module.
I test my application on OS 657e, 657f, 657g, Open AT 3.19, Open AT 3.20, Open AT 3.21, WIP 3.10.1030, WIP 3.10.1032, WIP 3.10.1034.
Always i have the same bug.

I see this bug if I use WIP.
Can any body help me.

If your going to make identical posts in multiple forums, always include links between them - otherwise you will waste peoples time if they answer in one forum, not knowing that the answer has already been given in the other!

See: viewtopic.php?f=3&t=3904&p=15264#p15264

Have you tried increasing your Stack size :question:

See: viewtopic.php?f=78&t=3562&p=13581&hilit=stack+size+wip#p13581
And: viewtopic.php?f=16&t=3655&p=14116&hilit=stack+size+wip#p14116
And: viewtopic.php?f=3&t=3244&p=12129&hilit=stack+size+wip#p12129

I set stack size 4069
u32 wm_apmCustomStack [ 4096 ];

I test my application
when I only recv data my application work more then 1,5 hour whithout error
when I only send data I have error at 10-15 minute

that sounds like you have a memory leak in your application. (propably someware within your send data code)
does your application wait for the ‘data-sent’ event before sending new data?
does your application check if it is able to send data or does it call wip_write regardless?

I also have the same problem when I trying to connecting to non-existing server.
I set in wip_TCPClientCreate my IP and that Port on which not exist my server application.
From some time (10-20 minute) i have ARM Exception 1
This is my code.
