WebAug 29, 2016 · The best case interrupt latency is 242 cycles, which for a 667 Mhz Zynq is about 0.36 µs — not bad. Worst case in the measured scenarios is with a clean L1 and L2 caches, as well as empty TLB and branch predictors. In that later case, measurements show a worst case of 3996 cycles or nearly 6 µs.

STM32 HAL_DELAY hangs with HAL_GetTick=0 [closed]

WebIf you call the HAL_DELAY in the interrupt that has greater priority, then systick counting is stopped. So the HAL_DELAY gets stucked in the endless loop do...while, because the systick isn't counting. The remedy would be to set Systick interrupt at higher priority.
