Extracting EW specific error code

Question

Good day,

When EwPanic is raised, is it possible to query the EW stack for a specific error code associated with EwPanic?

Answer 1

Hi,

typically you get an error message - therefore it is always helpful to have a serial connection running on the target and a terminal on PC to show the messages.

What error do you have?

Best regards,

Hi Manfred,

This the the implementation Is copied:

/*******************************************************************************
* FUNCTION:
*   EwPanic
*
* DESCRIPTION:
*   The function EwPanic() will be called by the Run Time Environment if a fatal
*   system failure is detected.
*
*   This function can be adapted to decide what to do when a system failure
*   is occured. Generally EwPanic() should log the system failure and restart
*   the system.
*
*   For debugging purpose EwPanic() can run into a for-ever-loop or it can
*   cause a monitor breakpoint, etc.
*
* ARGUMENTS:
*   None
*
* RETURN VALUE:
*   EwPanic() will never return.
*
*******************************************************************************/
void EwPanic( void )
{
  /* Print out the message ... */
  EwPrint( "\nPANIC: System halted\n" );
    
  ASSERT(FALSE);

}

So in my particular case, I called Add(..., 0); on the same object twice. I'm hoping there is a text string which gives the reason, Eg. Double Allocation.

PANIC: System Halted is vague, and a specific error string would reduce my debug time, because EwPanic can happen for all sorts of reasons.

 

Kind Regards,

Rob

Hi Rob,

yes, the EwPanic() function does not report the error. But before EwPanic() is called, the error message is printed via EwPrint(), reporting the location where the error happend and the reason that causes the error. EwPanic() is just the final state.

Manfred.
