Subject: RTEMS error codes
To: Sebastian Huber <sebastian.hu...@embedded-brains.de>
Hello,
I'm trying to integrate a USB device stack in 4.11.3 for STM32H7 and
after I called my USB initialization function just before initializing the
shell RTEMS
task I get an exception and _Terminate is called.
void _Terminate(
Internal_errors_Source the_source,
bool is_internal,
Internal_errors_t the_error
)
{
ISR_Level level;
_ISR_Disable_without_giant( level );
(void) level;
_SMP_Request_shutdown();
_User_extensions_Fatal( the_source, is_internal, the_error );
_Internal_errors_What_happened.the_source = the_source;
_Internal_errors_What_happened.is_internal = is_internal;
_Internal_errors_What_happened.the_error = the_error;
_System_state_Set( SYSTEM_STATE_TERMINATED );
_CPU_Fatal_halt( the_source, the_error );
/* will not return from this routine */
while (true);
}
by printing _Internal_errors_What_happened in debugger I get this
p /x _Internal_errors_What_happened
$2 = {the_source = 0x9, is_internal = 0x0, the_error = 0x20001100}
how should I interpret the value 0x20001100 ?
I would like to understand what is the nature of the error I'm having.
How is this value composed ? maybe 0x1100 is added over 0x20000000 ?
I couldn't find in the code so far .. a pointer to the piece of code where
this is done
would be helpful.
regards,
Catalin
