There seems to be a limited amount of resources available specifically for hardware timers, although I found some information related to PWM. The Problem: I'm using the stm32_timer_initialize function (example: stm32_timer_initialize("/dev/timer7", 7)) to initialize the timer driver. However, when I run the provided basic timer application, a hardfault occurs at line 256 of the timer.h file. This line seems to be the root cause of the error. What I've Tried: * I've verified that the timer driver is initialized correctly with the appropriate device name and timer number for the board. * I've reviewed the timer configuration to ensure it aligns with my application's requirements (clock source, prescaler, count mode). * I've searched online forums and communities for similar issues but haven't found any relevant solutions. Request for Assistance: If anyone has encountered and resolved similar hardfault errors related to hardware timers on the STM32F427AI, your insights would be greatly appreciated. Any suggestions or resources regarding hardware timer configuration for this board would be extremely helpful. Additional Information (Optional): * If possible, I can share more details about the specific timer configuration and the code snippet around line 256 of timer.h. Thank you for your time and support.[cid:ii_19005865fd8cb971f161]
