I am not able to flash the initial version of Amazon FreeRTOS onto the ESP32 chip.

When I try to run the following command:

Code: Select all

idf.py -DVENDOR=espressif -DBOARD=esp32_devkitc -DCOMPILER=xtensa-esp32 build

I get the following error:

Code: Select all

Ideally I should be able to able to build this and then flash onto my device.
