1. UEFI for ARM/ARM64 on QEMU

    One really useful thing that happened at Linaro Connect last week was that Ard Biesheuvel managed to complete the port of UEFI to arm and aarch64 QEMU. This has been a component missing for us to enable what is really the standard development environment for most Linux devs. Ard has …

  2. Foundation Model - a line in the sand?

    When ARM announced its 64-bit architecture, this was eventually followed by a free (as in beer) software model of that architecture. This model is called the Foundation Model, and although somewhat of an unwanted stepchild next to the commercially available (read expensive) FVP Base model, it is periodically updated.

    Unfortunately …

  3. BeagleBone Black booting

    The TI Beagle development boards have a ... weird (software) boot architecture. All documentation I was able to find online for running Linux on them is based around a set of cryptic and very specific instructions to:

    Well, I did sort of start writing some blog posts last year, mainly about technical stuff that might be useful to others (and to myself when I forget). But at some point my MovableType installation became a bit ... confused ... and at the same time the company behind MovableType started seriously …

  5. Booting a full system with Ovmf

    QEMU supports exporting a directory structure in the host machine filesystem as a block device containing a FAT filesystem. If you think about it, that's pretty much magic. This is really handy for kernel (U)EFI feature testing, since it means I can just throw a Linux kernel (with an …

  6. Running UEFI virtualised

    UEFI is a portable platform firmware standard, although in practice it has up until recently been used only on IA64 and amd64/x64 platforms. The opensource implementation (TianoCore EDK2) includes support also for ia32 and ARM (aarch32) platforms.

    I develop for the ARM platform, but I sometimes need to verify …
