custom board

[folibis]

I try to setup a custom board.
I have a supported board WeAct STM32F405RTG6 and so my plan was to begin with that.
I've just copied the board files from zephyr/boards/weact/stm32f405_core into my folder myboard:
All inside zephyrproject folder.

So my folder looks like:

├── boards
│   └── custom
│   └── myboard
│   ├── board.cmake
│   ├── board.yml
│   ├── Kconfig.myboard
│   ├── myboard_defconfig
│   ├── myboard.dts
│   └── myboard.yaml
├── CMakeLists.txt
├── prj.conf

now I try to build that with:
west build -b myboard
but for some reason I get dts include error:

In file included from :
/home/user/zephyrproject/myboard/boards/custom/myboard/myboard.dts:9:10: fatal error: st/f4/stm32f405rgtx->pinctrl.dtsi: No such file or directory
9 | #include <st/f4/stm32f405rgtx-pinctrl.dtsi>
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
compilation terminated.

the original file actually contains:

#include <st/f4/stm32f405Xg.dtsi>
#include <st/f4/stm32f405rgtx-pinctrl.dtsi>
#include <zephyr/dt-bindings/input/input-event-codes.h>

I just copied it as is.

So what a problem? Should I update the include path somehow?

stm32f405rgtx-pinctrl.dtsi is part of hal_stm32 https://github.com/zephyrproject-rtos/hal_stm32. Do you have it under zephyrproject/modules/? Though if you can already build for weact/stm32f405_core you should already have it.

[folibis]

Actually yes, I have all these files,
stm32f405rgtx-pinctrl.dtsi is under zephyrproject/modules/hal/stm32/dts/st/f4 folder.
But for some reason weact/stm32f405_core finds this include files, but my custom board does not.

Open Kconfig.myboard and try replacing config BOARD_WEACT_STM32F405_CORE with config BOARD_MYBOARD.

Hi @folibis,

You can have a look into branch v4.2.0. This creates a module but the principle is the same
