Changed from STM32L476xx to STM32L4A6xG and the Serial communication clock has 7% of difference at 115.2kbaud rate.

I have firmware file for the STM32L476xx and in the application they decided to use the STM32L4A6xG instead for future upgrades.

I tried to load the original firmware and it seems that the application is not running properly anymore. All initializations are OK but the UART seems to have an issue with the clock...

I would expect as in the website that they are compatible versions.

Do I need to create a new project?

Do I need to make any further modifications?

Thanks

What's the primary clock source?

Watch for HSI, and perhaps MSI, clock sources and CALIBRATION values.
