Where are all the new STM32 boards?

Hi I have just made the move to PlatformIO from Arduino IDE. I mostly use custom STM32 mcu’s and use the official STM32 Arduino core
The latest version (2.0) included many more mcus esp L0 L1, L3 and L4 range. I mostly use the generic ones as I make custom boards for each project but PlatformIO seems to be a long way behind available MCU’s how often do they refresh from the official cores? not having the mcus supported is a show-stopper.

I notice you have recently upgraded STM32cube support is Arduino next?



PlatformIO must create a board definition file (JSON format) to create support for a certain board. Not all STM32Duino listed boards currently have an equivalent in PlatformIO – that’s tracked in (and was also previously tracked in various smaller per-board issues)

The used Arduino core in PlatformIO is already the latest stable 2.0.0, those files do not need updating.

This also means that one can write a board definition file and reference the wanted chip variant themselves. An example of that can be found in Nucleo_f446ze does not support Arduino framework. Looking for advice, where support for the “Generic F446ZETx” board is added with one board definition file (which is basically one file copied + two additional entries).

Btw, a lot of the “Lx” boards are listed without “STM32” before them, the “Nucleo L412KB” e.g., so to get those better type “L0” or “L4”. Search through to confirm that a board does or does not exist in PlatformIO.

Thanks for your quick reply @maxgerhardt, that explains the situation well.
I have in the past created my own stm32 variant for arduino ide for a MCU that they had not yet included it was a ball ache but I followed their wiki here and it did work in the end.
I was really pleased to see that with version 2.0 of their core came support for so many more meaning I had more options already done :slight_smile:
Issue #559 referenced above would be a great solution as ST seems to be driving towards supporting the whole range and manually keeping up would be difficult.
Do you also have a guide to creating a Json from a core supported mcu ?
Thanks again for your help.
