[ECOS] Error message...

[Cristiano Ligieri Pereira]

Hi all,

What's the exact meaning of this [error] message? 

"Program received signal SIGTRAP, Trace/breakpoint trap.
0x62160 in some_function ()"

Is it an error in my application? If not, can I avoid (by doing some
configuration) having it stopping my application. 

PS: It comes out from the Compaq Ipaq running eCos. I'm using the serial
port to debug it and see the messages.

Thanks,
Cristiano.

It definitely is in you application.  Since eCos is designed for embedded
use, it makes no sense [normally] to go on if such a thing happens, as
this is often quite serious.  You'll have to debug your application and
fix it, sorry.

I'd guess it means that the program ran away and ended up executing garbage.

Basically, the error means that there was some sort of execution
error - probably an illegal instruction.

First thing would be to use GDB and see if you can get a backtrace.
Then you can figure out how it got there.
