[feat] add: canio-debug-support and simple-hf-decoder

[marinauterion]

fix: stlink-config to use hla_swd instead of swd for h7x
add: python-script to parse canio-uavcan-hardfault-dump

PROBLEM TO SOLVE:

On boards with low non-volatile memory nor sd-card the hardfault needs to be extruded as efficient as possible.

The Board does provides a minimalistic hardfault_dump.
BUT: A binary-blob can not be fed into postmortem-option

SOLUTION

A parser-script to parse hardfault-blobs and provide a gdb-postmortem valid format

The Hardfaultparser:

• explicitly for ARMv7-M + FPU (canio, STM32F412CE)

TEST

python3 hardfaults_decode.py hardfault_test_files/dump1.dmp
Task:  'task_watchdog'  pid=222  line=173
File:  'armv7-m/arm_hardfault.c'
PC:    0x0805b236  LR: 0x0805b1fb  SP: 0x2001b8c0
Wrote: hardfault_test_files/dump1.hardfault.log
Wrote: hardfault_test_files/dump1.coredump.txt

The different Stackvalues relate to the Firmware-Logic

1. print hardfault (expected output)
2. write hardfault to Mem

FUTURE

• also decode comprimized blob
• arch-indepedant blob -> analyze elf/bin-file to get specific informations
