FT-TXT

This repository contains the firmware for the TXT controller based on BUILDROOT. For questions about the software, please contact fischertechnik-technik@fischer.de.

Quick Start

With existing development environment you can use the following commands to build a firmware image for the TXT controller.

cd FT/FT-TXT
git pull
./Make-TXT-Bootloader.sh
./Make-TXT-Buildroot-Clean.sh
sudo ./Make-TXT-Image.sh

The compressed generated image file you can find in ../ft-TXT_Build_XXX.img.zip

Setup Build Environment

To build the BSB and the Bootloader you will need a linux system with a development environment. The making of BSP was tested with Ubuntu Mate 16.04 and Ubuntu 18.04. Install the following linux packages first.

cd ./FT-TXT
sudo ./Linux-Pakete-Required.sh
(sudo ./Linux-Pakete-Extra.sh)

Making of Rootfs, Bootloader and Kernel

Initial

1. Create the working directory and change to it

mkdir FT
cd FT

2. Clone the FT-TXT repository

git clone https://github.com/fischertechnik/FT-TXT.git
(git clone https://gitlab.com/fischertechnik/FT-TXT.git)

3. Create directory for the toolchain

sudo mkdir /opt/FT
sudo chmod a+rw /opt/FT

Frequently

4. Change to the FT-TXT directory

cd FT-TXT

5. Build Bootloader

./Make-TXT-Bootloader.sh

The generated bootloader binaries can be found in ../u-boot/bin

6. Clone, configure and build Buildroot

./Make-TXT-Buildroot-Clean.sh

This script clones Buildroot, setup the right commit, patch and copy auxiliary scripts. Afterwards the Buildroot will be built.

An incremental reconfiguration with incremental build can be started via the script:

./Make-TXT-Buildroot-Incremental.sh

The output can be found in FT-TXT/../buildroot/output/images.

7. Bundle build result into image file

sudo ./Make-TXT-Image.sh

The output can be found in FT-TXT/...

Optional

8. Create Update scripts

./Make-TXT-UpdateScripts.sh
./Sign-Connect-Reader.sh
./Sign-TXT-UpdateScripts.sh

Update scripts can be used to update the firmware on a TXT without using a flash card. The update scripts and signatures can be found in FT-TXT/../update.

9. Create Graphs

./Make-TXT-Graphs.sh

Graphing the dependencies between packages, build duration and filesystem size contribution of packages. Required packages: sudo apt install python-matplotlib python-numpy You will find the generated graphs in FT-TXT/../buildroot/output/graphs/.

Additional Scripts

Description of additional scripts can be found in Additional-Scripts.md.
