esp-thread-br router build fails with Errors. (TZ-197)

[topraveenpaul]

Target hardware: The Wi-Fi based ESP Thread Border Router consists of two SoCs:
Host: Raspberry Pi 4 8GB on Ubuntu 20.04 LTS 64 bit.

Followed the exact steps detailed here: https://docs.espressif.com/projects/esp-thread-br/en/latest/esp32/dev-guide/build_and_run.html

Succesfully completed until :
esp-idf/examples/openthread/ot-rcp
idf.py --preview set-target esp32h2
idf.py menuconfig
idf.py build

Encountered the below error while building the esp-thread-br.

cd esp-thread-br/examples/basic_thread_border_router
idf.py menuconfig
idf.py build

The build step failed with below errors. Please check the attachment for the complet logs.

Question: Is there a working code that I can simply build and flash it to the board? Is there any specific commits that is 100% working?

HINT: Please check that the function name is correct. Also it is possible that you've forgot to import esp_openthread_task_switching_lock_release library(s) in header file or add the necessary REQURIES component. Try to add missing libraries to your project header file or check idf_component_register(REQUIRES ...) section in your component CmakeList.txt file. For more information run 'idf.py docs -sp api-guides/build-system.html'.
Also, please check if the function has been removed, renamed or replaced by an alternative function - refer to the migration guide for more information.

@topraveenpaul Seems you were using an old IDF version, could you fetch the latest IDF master branch and try again. Feel free to comment if any further issues.

[topraveenpaul]

@chshu . Thank you for your response. Yes, it works after I feteched from the master. I will close the issue now.
