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.

A guide for adding or updating packages can be found here:

• Adding Debian packages
• Updating Debian packages

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

Note: Keeping the host-side's rootfs in sync with the target' is recommended to avoid issues. Therefore, using NFS to share the host-side's 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.
