Abbreviated frequently as a3x. Retired in favor of a4x in February 2024 after 5 years of faithful service to the project.
Old boot firmware for the XR/station architecture, written in xr17032 assembly and dragonfruit.
Makes heavy internal use of NVRAM variables and a device tree model.
Download the XR/station sdk, and place it in a folder titled sdk in your current directory.
Then run the build.sh script using the path you'd like to place the ROM file as the argument.
Example:
./a3x/build.sh ./rom.bin
