[ECOS] Can't figure out how to use CYG_ASSERT()

[Grant Edwards]

I've searched docs and can't find anything on how to use
CYG_ASSERT().  According to the usage note in cyg_ass.h, the
usage is:

// Usage:       #include <cyg/infra/cyg_ass.h>
//              ...
//              CYG_ASSERT( pcount > 0, "Number of probes should be > 0!" );
//      
//      which can result, for example, in a message of the form:
//      ASSERT FAILED: probemgr.cxx:1340, scan_probes() :
//                     number of probes should be > 0!
//      if the boolean "pcount > 0" is false.

But that doesn't work for me.  Anytime get to a failed
CYG_ASSERT(), there is no message, the board just resets.

Do I have to define some sort of handlers for CYG_ASSERT to
call?  Isn't there a normal assert macro that just "prints a
message and halts" when the condition is false?

I guess I'll define one, but I thought there already was
something like that.

Try enabling 'CYGDBG_INFRA_DEBUG_TRACE_ASSERT_FANCY'
