FreeRTOS issue with NVIC registers

[AleksandrVin]

When using cmsis_rtos_v2 or v1 implementation generated from STM32CubeMX execution asserts on "obtained from hardware parameter. I can't understand what causes this but it is certainly incorrect and manual variable modification helps this code to pass. This code works on real bluepill stm32.

File: port.c from cmsis_rtos_v2

		#ifdef configPRIO_BITS
		{
			/* Check the FreeRTOS configuration that defines the number of
			priority bits matches the number of priority bits actually queried
			from the hardware. */
			ulMaxPRIGROUPValue = 3; // qemu is broken here. was 4294967295
			configASSERT( ( portMAX_PRIGROUP_BITS - ulMaxPRIGROUPValue ) == configPRIO_BITS );
		}
                #endif

I assume that ulMaxPRIGROUPValue is incorrect. Due to an error in NVIC register values.
This one probably

volatile uint8_t * const pucFirstUserPriorityRegister = ( volatile uint8_t * const ) ( portNVIC_IP_REGISTERS_OFFSET_16 + portFIRST_USER_INTERRUPT_NUMBER );
