General issue report

$ cat $HOME/esp-idf/examples/common_components/env_caps/esp32c3/Kconfig.env_caps
config ENV_GPIO_RANGE_MIN
    int
    default 0

config ENV_GPIO_RANGE_MAX
    int
    default 19
    # GPIOs 20/21 are always used by UART in examples


$ cat $HOME/esp-idf/examples/common_components/env_caps/esp32c2/Kconfig.env_caps
config ENV_GPIO_RANGE_MIN
    int
    default 0

config ENV_GPIO_RANGE_MAX
    int
    default 20

GPIO 19/20 of ESP32C2 are used by UART so ESP32C2's ENV_GPIO_RANGE_MAX is not 18?

Thanks for pointing this out, we'll update the caps to better reflect which pins should be used in the C2 examples.
