Hi, 
I am using ADC1 on stm32H563ZI nucleo board with trustzone enabled, I am not getting proper adc values (getting adc count of 822). When trust zone is disabled I am getting proper value of around 4095 with input of 3.3Volt .
I am attaching the project.
Please help with this issue.

Hello ST support

Has there been any progress on this subject? We are facing the same issue with our STM32H562.

When the TrustZone is enabled, the ADC readings are far too low. 

Can you please provide us with a solution or workaround to that problem? Despite of disabling the TrustZone ;)

Thanks and best regards

Ivo
