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

[freeflyer]

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 ?

Official create new project and import ioc into it. (imported is pinout and setings)

Unofficial ioc is text file open in editor (PSPAD NOTEPAD) and change ID , use one from official ioc ...

Thanks, I did try that but with no sucess

I generated a new project in STM32CubeMX for the STM32L433RCT6, then copied the .ioc file into my existing STM32CubeIDE project (for the STM32L433RCT6P)

But when I open the .ioc in STM32CubeIDE, it still shows the VDD12 pins (which are only used on the STM32L433RCT6P)

I restated STM32CubeIDE and this time it worked, although I've obviously lost all my periperhal and IO settings etc

So I edited the original .ioc file and did a find for STM32L433RCTxP and replace with STM32L433RCTx 

This appears to have worked, but in the folder there is a (linker?) file which has the 'P' designation called "STM32L433RCTXP_FLASH.ld" i.e. has the P suffix

Will this be ok or do I need .id file without the P suffix ?

 

Can I flash this build using STM32L433RCTx to the NUCLEO-L433RC-P ?  There are no VDD12 pins on the STM32L433RCTx which means there will be 2 additional GPIO pins, but so long as I dont use these additional GPIO pins will the NUCLEO-L433RC-P still work ?

CubeMX

and linker file you can rename to any and set it in linker config, normal way i use edit ioc in empty folder and generate create new all files (of course without user codes). Try delete .ld and regenerate ioc... exist many ways

 

[freeflyer]

Will the linker file be the same for both devices ?

Hello,

You may use "List Pinout Compatible MCUs" option, 

Then look for STM32L433RCT6 in the list and click "OK import"

You will be asked to generate a new project where you need to add your user code from the STM32L433RCT6P project.

Thanks

I tried that but get the error "Heap memory threshold exceeded warning"...

What does this mean ?

This is what it shows when I build code...

 

Memory region Used Size Region Size %age Used

RAM: 8 KB 48 KB 16.67%

RAM2: 0 B 16 KB 0.00%

FLASH: 43344 B 256 KB 16.53%

It seems to be an issue with Java and the numer of parts searched for.

If I narrow the search by selecting the series (STM32L4) and package (LQFP64) then it works... BUT, there is no Import (or Export) button, just a Close button....

 

Note I am using both PC and Mac and both behave the same

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