STMCubeMX migration ends with successfully imported but nothing is really there.

[Alejandro Bizzotto_65856]

I have a project with the STM32H753IIT6 with 9 free pins on it all of them labeled and many peripherals configured. I want to migrate to STM32H7R3I8T6 which I understand is the same family of MCU, it should be possible. 

I followed the steps in How to switch from one STM32 to another using STM3... - STMicroelectronics Community

and after selecting the document from where to import I get the "Project is successfully imported. Import RCC : PASS" dialog, but all the configuration remains in default state, nothing has changed. 

I also tried to create a new project with the same MCU as before (STM32H753IIT6) and it was really imported; all pins are there.

Also tried to create a new project with the STM32H753IIT6, assign a few pins, save it and imported this one into the STM32H7R3I8T6 but the result is the same it says it was success, but nothing is changed.

Should I do something different of is this some bug? how can we figure this out?

Hello @Alejandro Bizzotto_65856 

Actually, STM32H753IIT6 and STM32H7R3I8T6 are not pin-to-pin compatible, to check the list of pin-to-pin compatible go to Pinout -> List Pinout Compatible MCU and check the list.

Otherwise, I suggest that you refer to this AN Migrating from STM32H730 and STM32H750 to STM32H7Rx/7Sx MCUs - Application note , it may be helpfull.

KR,

Ok, I thought CubeMX will do what it could no matter if they are pin compatible or not. So, there is no automatic or semi-automatic solution to this, right?
