STM32CubeC5 initial release by gautierg-st · Pull Request #352 · zephyrproject-rtos/hal_stm32

gautierg-st · 2026-03-16T14:53:11Z

This PR adds the STM32CubeC5 (HAL, LL and CMSIS) along with the pinctrl dts.

STM32CubeC5 introduces the new HAL2 and therefore uses a different layout than former HAL.

Pinctrl generation is different (extracted from json instead of xml) and necessitates a new generation script.

mathieuchopstm · 2026-03-16T15:22:52Z

Nit: rename commit scripts: genpinctrl: add jinja template to scripts: genpinctrl: add jinja template for HAL2 or something like that

Also: since this template is identical to pinctrl-template.j2 (minus STM32F1 support) except for genpinctrl.py --> genpinctrl_cubev2.py, why not just make the tool's name a Jinja template variable instead, and share the template between HAL1 and HAL2 scripts? (or rather, pass whether target is HAL1 or HAL2 - see other comment)

I agree having a single template would be preferred

Templates are not strictly identical. I'll leave as is for the moment. It can be reworked later.

Otherwise LGTM

This script automates the generation of pinctrl files for STM32 HAL2. It will work the same way as the generation script for the HAL1 version with the consideration of several soc folders present in the directory given as input. It adds a new Jinja template for HAL2.
