Hi Joel,
When I set the breakpoint at boot_card, this how far I could get;
(gdb) step
_Terminate (the_source=RTEMS_FATAL_SOURCE_EXCEPTION,
is_internal=false, the_error=536874976)
at
../../../../../../../rtems.git/c/src/../../cpukit/score/src/interr.c:52
52 _CPU_Fatal_halt( the_source, the_error );
(gdb) step
arm_interrupt_disable ()
at ../../cpukit/../../../tm4c129e/lib/include/rtems/score/cpu.h:345
345 uint32_t basepri = 0x80;
(gdb) step
347 __asm__ volatile (
(gdb) step
357 return level;
(gdb) step
358 }
(gdb) step
And the backtrace is below
Program received signal SIGINT, Interrupt.
0x0000a6ac in _Terminate (
the_source=RTEMS_FATAL_SOURCE_EXCEPTION, is_internal=false,
the_error=536874976)
at
../../../../../../../rtems.git/c/src/../../cpukit/score/src/interr.c:52
52 _CPU_Fatal_halt( the_source, the_error );
(gdb) bt

Backtrace stopped: previous frame identical to this frame (corrupt stack?)
