We have problem when using the HSI clock on our custom board with the STM32H7A3

[MSale.1]

Hello,

We have custom board with the STM32H7A3 and when i configure the HSI i always get error at. it return HAL_TIMEOUT

    /* Wait till PLL is ready */

    while(__HAL_RCC_GET_FLAG(RCC_FLAG_PLLRDY) == 0U)

    {

     if((HAL_GetTick() - tickstart ) > PLL_TIMEOUT_VALUE)

     {

      return HAL_TIMEOUT;

     }

    }

I tried with the STM32H7B3 discovery board and its fine when i use the HSI with same configuration.

Attached you can see screen of my clock configuration.

HSI RC was divided by 2 in the configuration i just made it 1 and it worked
