The following instructions have been tested with Ubuntu 18.04 (64 bit) in a VMWare virtual machine.

This page refers to the BSP and ancillary tools listed in the following table:

U-Boot 2016.03(NXP imx-rel_imx_4.1.15_2.0.0_ga)
Linux Kernel linux 5.4.87 \
linux 5.4.87 + rt48

Show details for previous revisions of the BSP

PTXdist version 2019.09.0 is required to build the OSELAS.Toolchain-2019.09.1. This version may differ from the PTXdist version required to build the BSP itself. Ubuntu 18.04 is required for the toolchain.

Prerequisites

The BSP is available as a project ready to use with the PTXdist1) build system. As PTXdist runs on linux, first of all you need a development workstation (or a virtual machine) with a (preferably) recent Linux distribution installed. The distribution of your choice, however, may not have installed all required packages by default. Commonly missing packages (package names taken from Debian based systems) include:

  • autoconf
  • bc
  • bison
  • build-essential
  • dialog
  • flex
  • g++
  • gawk
  • gettext
  • git
  • libncurses5-dev
  • libxml-parser-perl
  • python-dev
  • quilt
  • texinfo
  • zip
  • socat
  • pkg-config

Although not required by PTXdist, we also recommend to configure and run a tftp server (for image download / update) and an nfs server (for network mounted rootfs) on your development host.

PTXdist set-up

It is recommended to first install PTXdist 2019.09 in order to build the toolchain (see note above).
Once the toolchain is compiled, install PTXdist 2020.01 is required to build the BSP.
You can always use a specific version of PTXdist by explicitly calling ptxdist-<version>.
Example:
$ ptxdist-2020.01

Please note:
The link /usr/local/bin/ptxdist always calls the PTXdists version installed most recently.

Starting with PTXdist 2014.07, ptxdist calls a script which tries to automatically determine and call
the required version by parsing the config files in the project directory.

Make sure the development host meets the prerequisites and download the required PTXdist tarball(s) (see Downloads page for URLs).

Install PTXdist version for building the Toolchain

Extract the tarball ptxdist-2019.09.1.tar.bz2 and install as follows: 

$ tar xvf ptxdist-2019.09.1.tar.bz2
$ cd ptxdist-2019.09.1
$ ./configure
$ make
$ sudo make install

This will install PTXdist to /usr/local/lib by default.

PTXdist configuration

After installing PTXdist it can be configured by: 

$ ptxdist setup 
 .config - PTXdist 2020.01

To personalise your PTXdist installation, please fill out:

  • User (username and mail address)

Depending on your environment, the most important settings are:

  • Proxies (ftp / http / hhtps proxies)
  • Source Directories (path for archive of downloaded source packages (aka local package pool))

For further details on setup options, please see the PTXdist manual.

Building the toolchain

See download page for links to toolchain download. If using precompiled toolchain install to /opt. Otherwise carefully follow the documentation for building toolchains found here or in the download section.
By default the toolchain will get installed to /opt/OSELAS.Toolchain-<version>.

Follow chapter “Building a toolchain” in the PTXdist manual and keep in mind:

  • When you are asked to run the command 
    $ ptxdist select ptxconfigs/...

    select this ptxconfig: ptxconfigs/arm-v7a-linux-gnueabihf_gcc-<version>_glibc-<version>_binutils-<version>_kernel-<version>-sanitized.ptxconfig (for TQMa7x)

  • To build the toolchain project you should install the corresponding PTXdist version for the Toolchain (as told in the documentation).

Install PTXdist version for building the BSP

Extract the tarball ptxdist-2020.01.tar.bz2 and install as follows: 

$ tar xvf ptxdist-2020.01.tar.bz2
$ cd ptxdist-2020.01
$ ./configure
$ make
$ sudo make install

Afterwards you can configure PTXdist

Extract the BSP sources

See the README file in the BSP archive for a detailed description of the zip contents

Extract the package TQ-TQMa7x-BSP-REV.0113.zip to any directory (e.g. /opt or /home): 

$ cd ~/home/workspace
$ tar -xvf TQMa7x.BSP.SW.SRC.0113.tar.gz
$ cd TQMa7x.BSP.SW.SRC.0113
