Debian toolchain installation for out of Debian builds

Installing the toolchain

To install the toolchain, please go through the following steps of the Debian Build Release guide:

1. Setup Development Environment
2. Installing required packages
3. Download Debian archive
4. Deploy/Fetch the sources and components

You will have a development environment from this point, including the toolchain and the packages ready to be used.

The GNU Linux toolchain gcc-linaro-6.3.1-2017.05-x86_64_aarch64-linux-gnu can be found at ~/debian_imx8mq-var-dart_debian_bullseye/toolchain.

Note: Alternatively, you can download the toolchain directly from the Linaro toolchain binaries archive. Anyway, If you're considering downloading the toolchain directly, please still follow steps 1 and 2.

Build the sysroot/rootfs

To build the rootfs, which can be used as the sysroot for the cross-compilation, please follow the steps of the section Setup and build Debian.

The Debian build script uses debootstrap to create a minimal Debian Bullseye system and adds the BSP support. Please consider installing extra (dev-)packages to your Debian file system as per your needs.

Please follow the Adding Debian packages guide to learn how to add packages to the rootfs.

You can look up the available packages for Debian Bullseye at the Debian packages directory.

Note: Keeping the host-side's located Debian rootfs in sync with the target one is recommended to avoid issues. Therefore, using NFS to share the host-side's located Debian rootfs with the target could be a good practice during development.

Please refer to the Debian Setup TFTP/NFS guide for more information on how to setup a TFTP/NFS configuration.
