Getting to blinky with an ESP32 board
I am trying out Zephyr following the "Getting Started" guide: https://docs.zephyrproject.org/latest/getting_started/index.html#build-the-blinky-sample
I've installed the toolchain and I am trying to get the blinky example running on an ESP32 board. I've installed the latest stable ESP toolchain according to the instructions here: https://docs.espressif.com/projects/esp-idf/en/stable/get-started/
To set up the build environment, I apparently need to set the following environment variable:
export ESPRESSIF_TOOLCHAIN_PATH="/path/to/xtensa-esp32-elf/"Unfortunately, there is no "xtensa-esp32-elf/" directory that I can find.
When I try to build the example, I get the following error:
not found - Please check your toolchain installation
It is probably something simple, but I'm stumped. Can someone point me in the right direction?
