Stuck at ESP_INTR_FLAG_IRAM

[yene]

I was able to setup the ESP32 toolchain and run the official hello_world project. But when running the ttn-esp32 hello_world I get the error 'ESP_INTR_FLAG_IRAM' was not declared in this scope

If I add the missing header it continuous with 'gpio_install_isr_service' was not declared

What did I miss?

Can you provide additional information?

• What version of the ESP-IDF library are you using?
• Which build system/IDE (make, cmake, PlatformIO) are you using?

I followed official tutorial so I guess the latest of master branch? I am using macOS 10.14.4, GNU Make 3.81

I fixed it by using the latest stable release instead of master branch

cd ~/esp/esp-idf
git checkout tags/v3.1.4
git clean -df
git submodule update --recursive
