Adapting BSP for an own product

we suggest to read the following pages before you proceed with this page
  1. preparing Development Host
  2. Building BSP with PTXdist

The BSP was developed for the starterkit . To use it in a product with special needs or a different basebord we suggest to define an own platform. To start with it make a copy of the platform definition and select the new platform definition 

$ cd <BSPROOT>
$ cp -r <BSPROOT>/configs/platform-tq-@mb_name_code@ 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 howto go further. Keep in mind that custom mainboards may need 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.
If creating BSP for a new motherboard, make sure to create new configurations for bootloaders and device tree.

Changing packages

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

Adding own packages

PTXdist needs a package for every bit you need in your root FS to guarantee reproducible builds. To add your 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. Type 

$ ptxdist newpackage

to see what package templates exist.

Partition scheme

Changing the partition scheme may affect the boot loader update capability and / or the kernel command line parameters!
