Esp32-WROVER Unable to include the header file esp32-pinctrl.h

[r0n9Y]

Description:
I was trying to build for esp32 WROVER and getting the following error:

zephyr/boards/xtensa/esp_wrover_kit/esp_wrover_kit-pinctrl.dtsi:8:10: fatal error: dt-bindings/pinctrl/esp32-pinctrl.h: No such file or directory
    8 | #include <dt-bindings/pinctrl/esp32-pinctrl.h>
      |          ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
compilation terminated.

I checked the repository 3.2.0, in both zephyr/boards/xtensa/esp_wrover_kit/esp_wrover_kit.dts and zephyr\dts\xtensa\espressif\esp32.dtsi. The header file esp32-pinctrl.h is included. But in the folder zephyr\include\zephyr\dt-bindings\pinctrl. The header file does not exist

• Windows 10 Pro version 21H2
• I tried to use #include <dt-bindings/pinctrl/esp-pinctrl-common.h> instead of using the missing header but getting the following error

CMake Error at C:/ncs/v2.1.1/zephyr/cmake/modules/dts.cmake:230 (message):
 gen_defines.py failed with return code: 1

@r0n9Y I am not able no reproduce the issue. Have you run west update as well? Which sample code you have been using for that?

My app is configured as a freestanding app for the esp32 board and I just ran into the same error message. I'm sure there are several causes but for me the issue was using the environment variable ZEPHYR_MODULES to add a custom module instead of EXTRA_ZEPHYR_MODULES which made zephyr/cmake not load the correct HAL, which is also module. Reading the docs says that ZEPHYR_MODULES needs to specify a full list of modules (including the espressif-HAL) but EXTRA_ZEPHYR_MODULES adds to the existing/predefined modules.
Make sure to remove the CMakeCache.txt file after changing to the correct environment variable and configure again.

@timkruse Did you manage fix the issue?

[timkruse]

Yes, after using EXTRA_ZEPHYR_MODULES instead of ZEPHYR_MODULES the esp32-pinctrl.h file was available again.

If I remember correctly I developed a custom module and wanted to make it available to the zephyr environment. So I added my new module to the ZEPHYR_MODULES environment variable. This resulted in the error message of the missing esp32-pinctrl.h because ZEPHYR_MODULES holds all modules and by overriding it with my custom module zephyr is in a misconfigured state. Therefore, I used EXTRA_ZEPHYR_MODULES to make my custom module available to the zephyr environment.

Thanks @timkruse for the response, I am trying to write a BLE firmware for ESP using zephyr, I have added the git-submodules and everything but same issue. Will try this and update.

I have the same issue as @r0n9Y. The folder/file dt-bindings/pinctrl/esp32-pinctrl.h does not exist. I also tried just using the zephyr/dt-bindings/pinctrl/esp-pinctrl-common.h (which i also had to modify from zephyr/dt-bindings/pinctrl/esp32-pinctrl-common.h to zephyr/dt-bindings/pinctrl/esp-pinctrl-common.h).
The error I get then:
devicetree error: C:/ncs/v2.6.1/zephyr/boards/xtensa/esp32_devkitc_wrover/esp32_devkitc_wrover-pinctrl.dtsi:15 (column 14): parse error: expected number or parenthesized expression

Have you been able to solve the problem? If yes, how?
