Not able to enable TIM4 interrupt in NUCLEO-F756ZG

[JJAYAR]

Trying out a simple timer w/ interrupt

I am using the below code to enable interrupt

However during debug when ever I go to

NVIC_SetVector(....)

or

TIM4->CR1 |= TIM_CR1_CEN; ;//-> CEN=1;//Start Timer4

I get an error

'Break at address "0x80009b0" with no debug information available, or outside of program code.'

// Enable TIM4 interrupt

//error occurs here

// NVIC_SetVector(TIM4_IRQn, (uint32_t)&TIM4_IRQHandler);

NVIC_SetPriority(TIM4_IRQn, 0); // Set priority

NVIC_EnableIRQ(TIM4_IRQn); // Enable interrupt

TIM4->DIER |= TIM_DIER_UIE;

//error occurs here

TIM4->CR1 |= TIM_CR1_CEN; ;//-> CEN=1;//Start Timer4

wondering if anyone has previous experience with a similar error

ANy comments welcome

Thanx in advance
