I'm learning to port FreeRTOS to my STM32F407, but I'm running into problems with HAL initializing TIM2.After HAL_OK the program is supposed to enable TIM2IRQ via NVIC_EnableIRQ(), but the operation of writing to NVIC->ISER doesn't seem to work.NVIC-...

I'm trying to use VS code to flash/debug my Stm32F407VET6. When I tried to flash I got following terminal output: "xpack-openocd-0.12.0-3/BIN/OPENOCD.EXE" -f ./openocd.cfg -c "program build/Stm32F4_Hello.elf verify reset exit" xPack Open On-Chip ...

I tried to enable RXNEIE with following code: USART2->CR1 = (USART_CR1_TE | USART_CR1_UE | USART_CR1_RE | USART_CR1_RXNEIE); But when I checked CR1 register, it's still set to 0: gdb: x /8ub 0x40004400 0x40004400: 45 0 0 0 0 0 0 0 I checked the manu...

I am trying to build a uart implementation from scratch to learn the Stm32, but such a code implementation seems to cause my Stm32F030 to go into Reset_Handler state.What might be wrong with my code? Thanks in advance! void uar2_rx_tx_init(void) { ...

HAL_OK is the return value of HAL_TIM_Base_Init() in HAL_InitTick()Core\Src\stm32f4xx_hal_timebase_tim.c: htim2.Init.Period = (1000000U / 1000U) - 1U; htim2.Init.Prescaler = uwPrescalerValue; htim2.Init.ClockDivision = 0; htim2.Init.CounterMo...

It seemed to be a heap size issue, when I lowered the heap size for the two task allocations hardfault resolved. Why would two 150 heap cause a stack with a total size of 1000 to overflow? Anyway thanks for the suggestions guys!

YES. I'm actually learning FreeRTOS based on an Udemy course. I'm sorry to ask such a *** question here, my debugger tells me that the CPU has been inside vTaskStartScheduler(), but I'm not sure where it's stuck because all that seems to be executing...
