Possible porting from MCU STM32F746ZG to MCU STM32F767ZGT6

[SGasp.1]

Hi folks,,,

I would like to understand how much is the effort of doing the porting from MCU STM32F746ZG  to MCU STM32F767ZGT6 ...

How many changes I should made?

Thanks a lot for this information but now the situation with the supply of micro as you know ia very bad

Switching between chips within the same family is typically very easy, as long as you're only using peripherals that are common to both chips. The same binary may even work without recompiling. You'll need to verify pinouts.

The biggest thing I see between these two is a different FPU, which may require a recompile with relevant settings if you use it.

Hello @SGasp.1​ ,

The MCUs STM32F746ZG/STM32F767ZGT6 are compatible and there is no big change between the IP parameters.

You can check the attached Excel file for more details.

For easy switching MCU to another, you can use STM32CubeMX tool by importing a previously-saved configuration to a new MCU project.

Have a look at the UM1718:

• 11.9 Switching to another MCU
• Tutorial 5: Exporting current project configuration to a compatible MCU.

 

Hope this helps you.

Hi . .

The MCUs STM32F746ZG/STM32F767ZGT6 are compatible and there is no big change between the IP parameters...

Which are the small changes to do ?
