I followed the steps described here:
And so far I have the toolchain working but I see that it's still compiling with the old g++.
Code: Select all

~/esp/esp-idf/examples/get-started/blink$ git status
On branch feature/esp32s2beta
In this example I run like describes the forum post:
Code: Select all
rm -rf sdkconfig build idf.py -D IDF_TARGET=esp32s2beta menuconfig idf.py build
idf.py -p /dev/ttyUSB0 flash
At the end I got it working and it compiled. But it was hard to discover that the build directories and sdkconfig needs to be completely wiped out in order to run.
And also as a user, is a bit confusing that when you open the sdkconfig you see:
# CONFIG_IDF_TARGET_ESP32 is not set
When the ESP32 target is set
Anyways so far working great. Looking forward running some benchmarking tests and even finding a way to compile a MESH Lamp and to set the WiFi per se (Since there is no Bluetooth)
Would like to know if it's possible to make this even easier so it has more user adoption. Looking forward how far I can go and to learn more of ESP-IDF
By the way I have a couple of questions:
- What is the LED GPIO of this, can I blink a LED?
- Where is the Board Schematic so I can discover more?
Thanks a lot in advance!
