Hello everyone,

I am trying to build the porting\_assistant example from the MM-IOT-ESP32 library ( [GitHub - MorseMicro/mm-iot-esp32](https://github.com/MorseMicro/mm-iot-esp32) ). When I try to build it I get an error.

The environment which I am coding in is VScode and my windows version is windows 11 pro. I downloaded the ESP-IDF V5.1.1 which is stated in the [read.me](http://read.me) from the mm-iot-esp32 library. I configured MMIOT\_ ROOT in the envirmont variables of windows.

I think I set everything up correctly. The complete terminal when I type in idf.py build:

I have no clue where to look anymore can anybody help?

Thanks in advance,  
Sten Pierik

Okay I found the problem, I didn’t set the IDF\_TARGET correctly. This needs to be esp32c3, esp32s6 or esp32s3. Now I can build it but I can’t flash the esp32 I got. I know that it is because the version isn’t compatible, but does anybody know if it is doable to rewrite the framework. So that so it can support a esp32 instead of one of the others?

Not yet, the limit on supported platforms is that we currently distribute `libmorse.a` as a precompiled binary. We will be releasing the source for this very shortly!
