Re: Getting to blinky with an ESP32 board
Did you complete “Step 3: Set up the Tools” on the esp-idf getting started page? If so, you should have run the install script and installed the ESP tools on your system. Depending on where you installed them, there should be a directory at either $HOME/.espressif (or %USERPROFILE%\.espressif on windows) or somewhere else if you installed them elsewhere. Once you find them, you need to set that environment variables for using that espressif toolchain:
export ESPRESSIF_TOOLCHAIN_PATH=<<DIRECTORY YOU FOUND EARLIER>>/tools/xtensa-esp32-elf/esp-2020r2-8.2.0/xtensa-esp32-elf/
For flashing, you’ll also need a version of esptool.py which you can get from cloning the ESP IDF then setting the path to it for Zephyr to find:
export ESP_IDF_PATH=<<PATH TO WHEREEVER YOU DOWNLOADED THE IDF TO>>

I am trying out Zephyr following the "Getting Started" guide:
Unfortunately, there is no "xtensa-esp32-elf/" directory that I can find.
