ADC Clock settings (PLL2) missing for STM32H743 after update from CubeMX v6.4.0 to 6.5.0

Hello,

After Migrating my STM32H743ZITx project from CubeMX version 6.4.0 to 6.5.0, ADC stopped working (stucks at ADC_Calibration function).

Found out that in v6.5.0 ADC Clock settings were removed for some reason.

Please see comparison below:

Also compared generated adc.c files. All Pheripheral Clock Init settings are missing.

 Is it a bug or a feature? How this problem could be solved using the latest CubeMX version.

Thanks in advance.

It's a known bug. I will try to find a thread that states this.

Absurd that they don't catch blatantly incorrect stuff like this before it's released.

Did you ever get any resolution on this? I just found exactly the same thing (using STM32H753).

Hi @Community member​ 

You have two options here:

a) roll back to the previous version of CubeMX and H7FW

b) copy/paste the necessary code block for ADC from the old project if you have such

It is unbelievable that for 3 months so far STM has not released any update on this.

I did roll it back. I would rather that than have to manually change the code each time. Hopefully next release they will fix it. It took 2.5 years to fix the H7 Ethernet drivers so I am not holding my breath!
