Write a test for the safety flags:

Setup

Set a marker in the safety flag to boot into the test
Override the error flag weights so they don't trigger safety mechanisms
Restart to test mode

Test

Trigger failure mechanisms for all flags (if possible) and check if they occur.
Clear up the safety overrides
Set result of test in backup RAM and restart

Flag Tests

ERR_FLAG_MEAS_ADC_WATCHDOG: manually reconfigure the Watchdog limits so they will trigger for sure.
ERR_FLAG_MEAS_ADC_UNSTABLE: Do not test
ERR_FLAG_MEAS_ADC_OVERFLOW: Do not test
ERR_FLAG_TIMING_MEAS_ADC: Manually rewrite ADC register, so the ADC is misconfigured
ERR_FLAG_MEAS_ADC_OFF: Disable the ADC measurement and reenable it.
ERR_FLAG_STACK: destroy stack corruption detection area
ERR_FLAG_SAFETY_ADC: Manually misconfigure safety ADC
All others flags are tested during development by manual debugger intervention.

Eval

Evaluate the test result after a restart

Implement this after release of v1.0 It is not high priorit. the correct working of the safetxy controller will be ensured by testing it during development.
