[HELP] STM32H7 timer driver usage

[geniusdo]

Description

I tried to use timer driver based on this page timer. But when I toggled the option TIMER ARCH IMPLEMENTATION, my nsh just stucked. Any more detailed do I need to know to get this through? Any helps will be appreciated!

there is no support for CONFIG_TIMER_ARCH in stm32h7 and there is no support for CONFIG_TIMER in any of upstream stm32h7 boards. You can see on stm32f4discovery how this can be done on board side:

https://github.com/apache/nuttx/blob/master/boards/arm/stm32/stm32f4discovery/src/stm32_timer.c and https://github.com/apache/nuttx/blob/46c3f354b38291ee400bdbece6945ae6ab883b29/boards/arm/stm32/stm32f4discovery/src/stm32_bringup.c#L364C15-L372

FYI: timer drivers in stm32 don't implement getstatus() operation required by TCIOC_GETSTATUS used in examples/timer, so this example won't work properly with stm32 chips.
