STM32CubeMx v4.6.0

STM32F4 v1.4.0

1. After close and open CubeMx project (create for STM32F4DISCOVERY), i see ADC1 config error (in the previous version of the same here):

2. I set USART speed 57600, it work on 115200 (in the previous version to work correctly):

3. After check and uncheck FreeRTOS checkbox, NVIC Sub priority becomes not available:

#nvic #adc #usart

Hello,

Can you please share your .ioc file.

Can you confirm the procedure: did you load an MX 4.5 based project with MX 4.6? Or did you start this as a new project in MX 4.6.

Thank you

Please note:

freeRTOSConfig.h defines (MAX_SYSCALL_INTERRUPT_PRIORITY) put some constraints on NVIC settings: interrupts that could potentially calling interrupt sage freeRTOS API functions must have a lower priority.

Moreover, the priority group is defined with 4 bit for preemption and 0 for sub-priority. So when freeRTOS is enabled, your subpriorites should be set to zero.

When freeRTOS is disabled, you can work with sub-priority 15 but in this case change the priority group to be 0 bit for pre-emption and 4 bits for subpriority.

When freeRTOS is disabled, i can not even choose sub priority, if freeRTOS is enabled/disabled.

When freeRTOS is disabled, you need to change the priority group to be able to choose sub priority > 0.
