  • Raspberry Pi receives strategic investment from Arm

    > Please correct me if I'm wrong.

    My memory told me it was the GPU that needed the blobs. So I asked at DDG

    https://duckduckgo.com/?t=ftsa&q=binary+blobs+and+the+Raspbe...

    Turned up this: https://wiki.debian.org/RaspberryPi and it says...

    > All Raspberry Pi models before the 4 (1A, 1B, 1A+, 1B+, Zero, Zero W, 2, 3, Zero 2 W) boot from their GPU (not from the CPU!), so they require a non-free binary blob to boot

    So the 4 (and I suppose the 5, if it ever actually comes...)

    Goes on to say:

    > Since then, Broadcom publicly released some code, licensed as 3-Clause BSD, to aid the making of an open source GPU driver. The "rpi-open-firmware" effort to replace the VPU firmware blob started in 2016. See more at https://news.ycombinator.com/item?id=11703842 . Unfortunately development of rpi-open-firmware is currently (2021-06) stalled.

    So there you are. Not wrong, are you, but not strictly correct, depending on "...to run properly" definition

    many of those demos work on the the entire pi model range

    pi3 support is only broken due to arm side problems, which could be fixed by just using a different bootloader

    and the https://github.com/librerpi/rpi-open-firmware codebase can already boot linux headlessly on both pi2 and pi3, it uses a different arm bootloader

    Yes, and some folks are reverse engineering their stuff:

    There is work being done on the RPi4, for example the SHA1 HMAC protecting the boot on the RPi4 had to be cracked (and was easily), I hear future versions have RSA signing support, so the proprietary firmware might become mandatory at some point.

    There is a project to create an open source version of the proprietary GPU firmware that boots into the ARM processor:

    I note that even the Raspberry Pi is moving towards locked down devices, the RPi4 has an (easily cracked) HMAC blocking booting into the open source firmware and I hear more recent hardware editions have RSA signing support in the bootrom code.
