MK22FN512VLH12 Zephyr build error

[laszlomonda]

Hi guys,

We need to port our bare-metal, KSDK-based firmware to Zephyr, but I can't even build the Hello World Zephyr sample application on the FRDM-K22F dev board:

Building hello_world
/bin/sh -c west build --build-dir /home/laci/download/hello_world/build /home/laci/download/hello_world --pristine --board frdm_k22f --no-sysbuild -- -DNCS_TOOLCHAIN_VERSION:STRING="NONE" -DBOARD_ROOT:STRING="/home/laci/projects/firmware-uhk" -DCONF_FILE:STRING="/home/laci/download/hello_world/prj.conf"

As it turns out, the missing MK22FN512VLH12-pinctrl.h file is not part of the Zephyr repository, but it's part of the https://github.com/zephyrproject-rtos/hal_nxp Zephyr module.

Strangely, the https://github.com/zephyrproject-rtos/zephyr/tree/main/modules/hal_nxp Zephyr module is already part of the main Zephyr repo, but it's almost empty compared to the above module.

The above makes me quite confused, and I need some help making Zephyr build on the MK22FN512VLH12.

I should also mention that I use Zephyr provided by the nRF Connect SDK and the nRF Connect for VS Code extension pack because we're also using nRF528* processors. I want to use the same environment to develop for both processors. According to my knowledge, this issue is not related to the Nordic tools.

Thanks in advance.
