The code assumes that when the systick counter hits zero, the timer interrupt will be taken before the loop can read the LOAD/VAL registers, but this is not architecturally guaranteed, and so the code can see a post-reload SysTick->VAL and a pre-reload clock_accumulated_count, which causes it to return an incorrectly small cycle count. By adding a ISB we overcome this issue. Signed-off-by: Adithya Baglody <adithya.nagaraj.baglody@intel.com> |
