How to retartget MCU in STM32CubeIDE (from STM32L433RCT6P to STM32L433RCT6)

freeflyer · ‎2025-07-08

I have developed software in STM32CubeIDE using the NUCLEO-L433RC-P dev board.

This board uses the STM32L433RCT6P (which has an external SMPS for VDD12 pins) but the PCB I am designing uses the STM32L433RCT6 (without external SMPS).

When my PCB arrives, I will need to retarget the MCU in STM32CubeIDE from the STM32L433RCT6P to the STM32L433RCT6, but I cannot see how to do this.

I tried to create a new project (including the .ioc file) using STM32CubeMX and copy files accross, but got into a mess and could not get it to work.

Ideally I would like to be able to easily switch between both MCUs, so that I can continue to develop the software on the NUCLEO-L433RC-P until my PCB arrives.

How do I retarget my software to the STM32L433RCT6 ?

Try to use the standalone version of CubeMx and use the latest version of it.
