Details

Summary
  • Make sure that STIMER0 is disabled before writting to it, since writing to an enabled STIMER will result in undefined behaviour.
  • It is unnecessary to reconfigure STIMER0 upon each et_start().
  • Make sure that MSR_HV_REF_TIME_COUNT will not return 0, since writing 0 to STIMER_COUNT will disable the target STIMER.
