Building Ubuntu images for ARM devices

Summary

Hackaday describes RootStock as a tool that creates an Ubuntu root file system for a Gumstix ARM board. The target board comes from Gumstix. The base system cost about 150 US dollars at the time.

Ideas

  • Cross builds produce packages for a different processor architecture.
  • RootStock automates building the root file system.
  • An SD card carries the finished system to the target device.

Insights

  • Build tools encapsulate many details but must remain reproducibly configured.
  • Serial consoles are indispensable for early embedded boots.

Recommendations

  • Save package sources and toolchain versions.
  • Test the image with serial boot output first.

Portable Linux devices remain demanding

Jenny List summarises Arsenijs Picugins’ experiences and shows why power supply, connectors, display and enclosure determine portable DIY builds. The ZeroPhone serves as a practical example. Raspberry Pi and BeagleBone are named as possible platforms.

Several Linux kernels run without a hypervisor

Hackaday presents Multikernel Linux, in which a host kernel divides up the hardware and starts further independent Linux kernels directly on bare metal. The project is called Multikernel Linux. It is not the historical microkernel-based MkLinux.
