Hard to help you if I don't have the exact setup.

Meanwhile, in the ioc file go to the "Project manager" menu, and uncheck "Use default firmware .."

Click on "Browse" and browse to the firmware package folder v1.1.0.

Hello,

Why are you not able to set PA9/PA10 for UART with v1.2.0?

Could you please provide more details on how you did proceed?

Hello @mƎALLEm,
f.e. i have old project for STM32C031, every time when i open .ioc i have next warning (Screenshot 1). If i click continue (v1.1.0) i can select PA9/PA10 for UART RX/TX (Screenshot 2). But if i click migrate i have next (Screenshot 3) - there is no UART. I can force change it in code, but it will be not work correctly.

thanks for helping

May be you need to share you project in a zip file.

What kind of project do you need? The problem is that when creating I can't select the version STM32Cube FW_C0 - 1.1.0. You can create an empty project for stm32c031 or stm32s071, select the version (you won't be allowed to select) STM32Cube FW_C0 - 1.2.0 and make sure that it is impossible to select usart1 for PA9 PA10, although in the old version it was possible and most importantly this feature is described in the chip datasheet. I can't send the old project for 1.1.0 because it is the property of the company where I work.

Thank you for helping

Can you show more specifically where you found this checkbox? I found only lines in the Project Manager where the version is indicated, but these fields cannot be changed in any way. For testing I use an empty project for stm32c071g8ux.

Use the standalone CubeMx, open the ioc file and you can find that option in Project Manager -> Project in the bottom of the screen.
