Jump to bootloader from Azure RTOS

[STarlink]

Hello,

I'm having some issue going from my user code running azure RTOS to the bootloader. I'm using a STM32U599

The code I'm using is the following, you can find online:

 

void JumpToBootloader(void)

{

uint32_t i=0;

void (*SysMemBootJump)(void);

/* Disable all interrupts */

__disable_irq();

 

/* Disable Systick timer */

SysTick->CTRL = 0;

 

/* Set the clock to the default state */

HAL_RCC_DeInit();

 

/* Clear Interrupt Enable Register & Interrupt Pending Register */

for (i=0;i<5;i++)

{

NVIC->ICER[i]=0xFFFFFFFF;

NVIC->ICPR[i]=0xFFFFFFFF;

}

 

/* Re-enable all interrupts */

__enable_irq(); 

__DSB(); 

    __DSB();

    __ISB();

/* Set up the jump to boot loader address + 4 */

SysMemBootJump = (void (*)(void)) (*((uint32_t *) ((0x0BF90000 + 4))));

 

/* Set the main stack pointer to the boot loader stack */

__set_MSP(*(uint32_t *)0x0BF90000);

 

/* Call the function to jump to boot loader location */

SysMemBootJump();

 

/* Jump is done successfully */

while (1)

{

/* Code should never reach this loop */

}

}

 

It works well in baremetal when doing the jump from the main before launching Azure RTOS, I can connect with cube programmer through USB.
In Azure RTOS it causes a restart.
What could be the cause? Do I need to stop ThreadX before ?

Regards

Jumping from rtos doesnt work for me as well, I think thats due to resources acquired by rtos, you can start your system intialiaze rtos do whatever you wanna do using rtos, set a flag in flash or rom that now you want to jump, and restart the system,,,,read the flag if its true, jump before initialization on rtos otherwise continue normal operations
