How to port ESP32-C3 to RT-Thread without IDF?

[BalanceTWK]

Hello everyone! I am from the RT-Thread community.

I am trying to use RT-Thread's scons build system to compile ESP32C3 firmware. Currently, the ESP32C3 BSP has been PR'd to the RT-Thread main repository by community members [url][https://github.com/RT-Thread/rt-thread/ ... ADME_ZH.md], but it is currently compiled using idf.
I have looked at two examples in idf: 1. esp-idf/examples/build_system/wrappers 2. esp- :Didf/examples/custom_bootloader/bootloader_override. Which of these two examples is more suitable for reference to port to RT-Thread's scons build system? Or can someone provide some other guidance on the porting process?

Thank you for your help!
