Does this have support for ESP32 ? For Zephyr ?

Chưa có ai nhận issue này.

## ESP32 - Zephyr

- Hardware description: ESP32_devkitc_wroom
- RTOS: Zephyr
- Installation type: micro_ros_setup
- Version of micro-ROS used: humble

I had been following this tutorial: [](https://micro.ros.org/docs/tutorials/core/first_application_rtos/zephyr/)
The building and rest kept failing at first and I dug in a lil bit and found the reason was that the sdk was older version which did not have xtensa needed gcc for the esp32. I changed it to 0.16.8 added esp32 to supported platforms. and now while building the firmware as per the tutorial as in using ros2 run micro_ros_setup build_firmware.sh keep getting this error below

```

Now i tried setting the path in environment variable like export CXX=/microros_ws/firmware/zephyr-sdk/xtensa-espressif_esp32_zephyr-elf/bin/xtensa-espressif_esp32_zephyr-elf-g++
export CC=/microros_ws/firmware/zephyr-sdk/xtensa-espressif_esp32_zephyr-elf/bin/xtensa-espressif_esp32_zephyr-elf-gcc
still the same error happens.
Also one more thing I had hardcoded the CROSS_COMPILE path as `set(CROSS_COMPILE "/microros_ws/firmware/zephyr-sdk/xtensa-espressif_esp32_zephyr-elf/bin/xtensa-espressif_esp32_zephyr-elf-" CACHE STRING "Cross compiler prefix" FORCE) `in _/microros_ws/firmware/zephyrproject/zephyr/cmake/compiler/gcc/target.cmake_ This was done because before the path was coming out wrong.

Any ideas on how to solve this ? Or is there any other way to implement MicroROS on ESP32 using Zephyr ?

Bắt đầu với build_firmware.sh và cấu hình CMake ESP32/Zephyr được hiển thị trong lỗi, đặc biệt là modules/hal/espressif/tools/cmake/project.cmake và zephyr/cmake/compiler/gcc/target.cmake. Tái hiện lỗi và kiểm tra cách tiền tố trình biên dịch và PATH được lựa chọn. Được xem là hoàn tất khi quá trình build firmware micro-ROS Zephyr theo tài liệu hoàn thành cho target ESP32_devkitc_wroom, hoặc khi issue được thu hẹp thành một cấu hình không được hỗ trợ.
