The ESP32's official RTOS development framework is ESP-IDF, which typically uses FreeRTOS. But I wanted to know if we can do Zephyr RTOS in ESP32? If so does it have some framework made by the vendors similar to ESP-IDF? Any references?

  • \$\begingroup\$ Technically, yes. However, like you figured, ESP-IDF is based on a modified version of FreeRTOS. So with ESP-IDF, you may see better support for what you are going to build. \$\endgroup\$ Commented Nov 28 at 16:20
