This repository contains a crosstool-ng configuration file to build a toolchain for the Raspberry Pi Zero W. The configuration was modified from the one available here to be more up-to-date with current releases of Raspbian.
This was necessary as arm-rpi-linux-gnueabihf-gcc will embed ARM Thumb code when linking to libc which is not
supported by the Raspberry Pi Zero W processor,
see here. This toolchain
produces 100% non-thumb ARM assembly.
This toolchain is mainly used to build Raspberry compatible builds of go-librespot.
