Embedded module TQMa335x - PTXdist Linux BSP documentation

We suggest to read the following pages before proceeding with this page:

The BSP was developed for the starterkit STKa335x. To use it in a product with special needs or a different basebord we strongly recommend to define your own platform.

First of all make a copy of the platform definition and select the new platform definition

$ cd <BSPROOT>
$ cp -r <BSPROOT>/configs/platform-tq-mba335x to <BSPROOT>/configs/<your-cool-platform>
$ ptxdist platform <BSPROOT>/configs/<your-cool-platform>/platformconfig

To start configuring your new platform type

$ ptxdist platformconfig

The first thing to change should be the platform name. Adapt things like kernel configuration, image creation etc. to your needs.

The new system will be built under <BSPROOT>/platform-<platformname_from_platformconfig>

Please read the build system documentation for further information. Keep in mind that custom mainboards may require changes in bootloader and device tree.
Give the new bootloader config and device tree a new name to cleanly distinguish them from the starterkit mainboard configuration.

When creating a new platform, make sure to create new configurations for bootloaders and device tree as well.

PTXdist uses release tarballs for software it loads from the net. You have to work with patches, if you need to make (permanent) changes to the source code. Follow the instructions of the developers section in the PTXdist manual.

Changes made in the build directories will be deleted, when PTXdist needs to redo a buildstep.

Everything that should be part of your rootfilesystem needs to be provided as a PTXdist package, in order to guarantee reproducible builds. To add your application software, files etc. you have to provide local packages. Follow the instructions of the developers section in the PTXdist manual. PTXdist provides templates as starting point for own packages.

Execute

$ ptxdist newpackage

for a list of available package templates.
