HAL_PWREx_ConfigSupply(PWR_LDO_SUPPLY) fails in HAL_MspInit.

[Kwame]

Hello,

I am currently working with the STM32H7R7I8T6 and I am having issues configuring the Power. When HAL_PWREx_ConfigSupply(PWR_LDO_SUPPLY) is called in the HAL_MspInit function, it fails waiting for the PWR_SR1_ACTVOSRDY bit to set. I have measured the output of the internal LDO from the VCAP pins and it gives me a value of 1.187V which is within the acceptable voltage range for Vcore and so thePWR_SR1_ACTVOSRDY is supposed to set. I am starting to think that the registers can't be written or read. If this is the case how can I fix it and are there other reasons why this could be happening?

Hi,

what did you set in Cube/ioc ?

What is content of PWR->SR1 (other bits?)  Is this ST or custom board?

I just updated cubeIDE to the latest version and it worked.
