Board Support Package

To support our rich list of hardware features we provide an professionally maintained, state of the art board support package (BSP).

The core components of the BSP are:

  • Linux kernel (version depends on SoC)

  • U-boot (2016.11)

  • Yocto/OE-core integration (2.2/morty)

    • Binary package feeds (Ångström/Toradex)
    • gcc 6.2
    • glibc 2.24
    • systemd 230

  • Firmware update support, extensible to do OTA updates

We provide access to our build server where one can download nightly builds of the BSP. There is a also an possibility to create custom jobs on the server depending on customer requirements.

Resources

Large portions of the BSP is provided as open-source and can be found on github/hostmobility.

The parts that are considered closed source are only accessible by our customers and are required to fully utilize the devices. If you have an MX-4 device you probably are a customer and will get access to this part of the BSP together with your device.
