Hi, if I make any calls to mailboxes or semaphores, my application crashes. I can't even debug what happenned, all I get is "Could not stop ARM device!".
If I comment out the calls to mailboxes (e.g. os_mbx_send) and semaphores (e.g. os_sem_wait) everything works fine.
And yes, I am calling the init functions for the mailboxes and semaphores, so that's not the problem.
Any ideas? I can post some of the code if need be. Thanks.

we first saw this problem as part of a very complex application that died with no apparent reason so we could not really tell why (it was all one large spaghetti - our own mistakes were interleaved!). sometimes an undef exception, sometimes the kernel hung in setting of a task priority, you name it. so just 3 days ago I decided that I had enough of this and managed to give Keil what they have been asking me for months now (this is an old problem!) - a simple test case. it took me 15 minutes to write. I swear.
yes, i too started with a large application, but have isolated the issue, i can provide a very simple program which will cause the crash. in fact if i have time i will post it.
Please do, and please also send it to Keil - Franc Urbanc is returning from his vacation soon. He does not yet know what awaits him :-)
