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.
