Adding STM32F373VCT to STM32 variants for ArduinoIDE

[ddano007]

Hi, I tried to add above mentioned processor to STM32 variants in Arduino IDE 2.0.3 according this manual
https://github.com/stm32duino/wiki/wiki ... 28board%29
but I can see no additional board part number in Generic STM32F3 series
I created all files, modified boards.txt and Readme.md. Isn`t it necessary is some way to "upgrade" the list of boards in Arduino IDE?

You have to reload the ide to see it. If not present then probably an error in your modification.

[ddano007]

I of course reloaded IDE. And of course I could made an error.
However: when I made "fake STM32F373" from existing 303V(B-C)T processor IDE also didn`t change the list of useable boards.
It looks like after modifying all files it`s necessary in some way to "refresh" board list for Arduino IDE. Just restart Arduino IDE is not sufficient

well, hard to help without see what you have done.

I`m trying to run STM32F373VCT processor from this repo:
https://github.com/stm32duino/Arduino_Core_STM32
There is already in Generic F3 series directory for STM32F373VCT, but in IDE I can see only few of F3 processors ( ... 358, 378 ), but not 373.
In attachment are my "fake STM32F373VCT" files modified from STM32F303V(B-C)T processor ( I can see it in IDE and compilation is working ).
1, I just copied and renamed all files from
C:\Users\xxx\AppData\Local\Arduino15\packages\STMicroelectronics\hardware\stm32\2.4.0\variants\STM32F3xx\F302V(B-C)T
directory, to new
C:\Users\xxx\AppData\Local\Arduino15\packages\STMicroelectronics\hardware\stm32\2.4.0\variants\STM32F3xx\F373V(B-C)T
directory an renamed 303 to 373
2, I modified boards.txt in
C:\Users\xxx\AppData\Local\Arduino15\packages\STMicroelectronics\hardware\stm32\2.4.0
adding info from boards_entry.txt in F373V(B-C)T directory
3, modified README.md in
C:\Users\xxx\AppData\Local\Arduino15\packages\STMicroelectronics\hardware\stm32\2.4.0
adding one line for new processor.
Close and open again Arduino IDE 2.0.3.
Nothing changed

Well, I do not advice to modify the folder as they are generated automatically. Simply add the linker script and a default generic clock config in the folder STM32F3xx/F373V(8-B-C)(H-T)

I've simply added the board entry of the STM32V373V in the boards.txt and it appears properly:

Thanks.
I deinstalled that repo and reinstall it. After adding lines to boards.txt I can see it in menu ( miracles hapens ).
Question:
In manual I`ve mentioned above is declared, that as clock source for generic boards is HSI. I want to use USB, and can`t find any configuration for it with HSI.
Can I use external 8MHz crystal in CubeMX clock configuratior or not?

[fpiSTM]

If your board have HSE you can use it else no.

[ddano007]

Thanks. Sorry for maybe stupid questions, but I`m not familiar with such things
So the step-by-step it will be:
1, run CubeMX
2, configure pinout for external 8MHz HSE and 32kHz LSE ( would be fine to have also LSE with external crystal for better stability )
3, add USB
4, solve clock cofiguration to have 72MHz core clock and 48MHz for USB
5, generate code
6, make ldscript.ld and generic_clock.c from generated code.
Or am I to generate ldscript.ld with default cofiguration BEFORE adding HSE, LSE and USB?

It`s working, great thanks for help.
