In the Software after calling WFI instruction (wait for interrupt) to wait for an interrupt to wake-up the micro-controller, it still sleeping for ever. In debug session by pressing next step in IAR, I can go out from deep sleep mode. WebSysTick-> CTRL = SysTick_CTRL_TICKINT_Msk; // systick IRQ on} What can cause such behavior? Maybe my approach is wrong, but I couldn't find good example for RTC tickless idle. What should happen with interrupts inside vPortSuppressTicksAndSleep()? What is the role of cpsid? Interrupts are necessary to wake up the MCU, but IRQ handlers shouldn ...

WebJul 8, 2024 · SysTick. We have a custom board based on a STM32G483 MCU (Cortex M4). We use the SysTick as a reference for software timers. The SysTick reload register is set to 0x00FFFFFF so as to have the fewest interrupts. The SysTick is clocked with the CPU clock at 128MHz, which means there is a SysTick interrupt every 131ms or so. WebSYSTICK is a peripheral designed by ARM. This means that it does not feature the typical Nordic interface with Tasks and Events. Its usage is limited here to the implementation of simple delays. Moreover, keep in mind that this timer will be stopped when CPU is sleeping (WFE/WFI instruction is successfully executed).
