Question

STM32H7 won't calibrate using STMCubeMX v6.13.0

CubeMX-generated code gets stuck on HAL_ADCEx_Calibration_Start(&hadc1, ADC_SINGLE_ENDED) using IDE v1.17.0 and FreeRTOS.

RTOS is using SystemCoreClock. HAL Tick is using TIM17 with a priority = 14 (Higher than SysTick Timer.)

Made AdcTask highest priority task. Ran ADC_Disable(&hadc1) to make sure ADC was disabled. All required GPIO Port Timers have been enabled. Not using DMA. I can't see any relevant difference between my code and the examples.

If I skip Calibration and then:

   ADC_Enable(&hadc1);

   HAL_ADC_Start(&hadc1);

   HAL_ADC_PollForConversion(&hadc1, 10)

The ADC enables and starts, but times out at the Poll. This could be a different issue, but it may also be an indicator of why it wont calibrate. ADC is configure to Scan 4 channels with EOS.

All other GPIO, UART, I2C, Timers work as expected.

A response would be appreciated.

    Hi @dbrooks ,

    - Can you try to increase the timeout value for ADC calibration? Does it help?

    - What about the configuration without FreeRTOS: do you face the same issue?
