Hi everyone,I'm using STM32L4R9 to develop product which run on RTOS kernel. Previously, I used a other Cortex-M4 chip run on RTOS platform in tickless mode, a 32 bit timer counter is used for calculate RTOS tick and this timer-counter able run on lo...

You're right. Actually, the more the chip wakes up to re-calculate tick when counter is overflow, the more possibily system can get faut (corner case, race condition ...). Btw, we also need Power profile of system, if chip wake up usually because of...

Hi Jack,It's a good idea but system that I'm working on is a bit critical, so it need to be configured 1000 tick per second. Then it will wake up every ~65s even if kernel is idle, more than that we have to cover if timer counter overflow very well,...

Hi JW,I also thought ab this but with configuration 1000 tick per second so I need smallest resolution for every tick is 1ms (2^16 / 1000 ~ 65 second). So after every 65s, the timer is overflow so it's a bit dificult if we schedule a timer > 65s, th...
