PLLP can't be turned on

[decook1110]

I'm working on page 30 of the STM tutorial for the B-G474E-DPOW discovery kit at this link

https://www.st.com/resource/en/application_note/dm00706304-buck-current-mode-with-the-bg474edpow1-discovery-kit-stmicroelectronics.pdf

 

I get this warning when I try to follow the directions

 

 

Can someone explain how to fix this so I can move to the next step in the tutorial.

I've tried looking up codegen in the reference manual and also how to manipulate ADC12.

Thanks

Dave

What is the chance this is a similar bug from https://community.st.com/t5/stm32cubemx-mcus/adc-for-stm32g474-how-to-select-pllp-clock-with-stm32cubeide/m-p/107224

Hello @decook1110 

In order to set the [PLLP Clock] or [SYSCLK] as source Clock for the ADC12 or ADC345, just change the clock Prescaler to Asynchronous clock mode in the ADC_Settings.

Best Regards.

Thanks for the work around, that fixed the clock so I can move past that,
