Hi,  
I’m trying to add support for the Particle Xenon, a discontinued nrf52840 device that uses the feather footprint and can be picked up for around $10 on the second hand market if you’re willing to put a UF2 boot loader on it.

However, I’m having issues compiling CODAL.

Looking for some directional advice here. Do I need to put a github issue to the cordal team?

Is it building with docker? otherwise, which version of arm-none-eabi-gcc do you have?

arm-none-eabi-gcc - (15:6.3.1+svn253039-1build1)

I’m following the instructions on the github page to compile without docker:

> **[microsoft/pxt-maker](https://github.com/microsoft/pxt-maker/)**
>
> MakeCode target for "Maker" boards (beta). Contribute to microsoft/pxt-maker development by creating an account on GitHub.

Using docker I was able to get past the pxt build part but got an error in build.py

I get the same error, trying to build the chain for “circuit playground bluefruit”:
