lbuild module: modm:crashcatcher

CrashCatcher hooks into the ARM Cortex-M HardFault handler and generates a coredump that can be used with CrashDebug for post-mortem debugging. You must place the CrashDebug binary in your path or alternatively set the environment variable MODM_CRASHDEBUG_BINARY to point to the enclosing folder:

• https://github.com/adamgreen/CrashCatcher
• https://github.com/adamgreen/CrashDebug

Note

The debugger can generate coredumps too In case you encounter a hardfault while debugging or you simply want to store the current system state for later analysis or to share with other developers, you can simply call the modm_coredump function in GDB and it will generate a coredump.txt file. Consult your chosen build system module for additional integration.
