Description:
This test verifies the Cortex-M HardFault escalation. Only for
ARM Cortex-M targets.
---------------------------------------------------------------------------
Building and Running Project:
This project outputs to the console. It can be built and executed on QEMU as
follows:
make run
---------------------------------------------------------------------------
Troubleshooting:
Problems caused by out-dated project information can be addressed by
issuing one of the following commands then rebuilding the project:
make clean # discard results of previous builds
# but keep existing configuration info
or
make pristine # discard results of previous builds
# and restore pre-defined configuration info
