See https://www.openbsd.org/armv7.html for the supported hardware for the 32-bit ARM port. There is some support for rpi3 on https://www.openbsd.org/arm64.html but it's limited - console is on serial (you will need a ttl serial interface), no SD card, and AIUI ethernet only works on rpi3b not rpi3b+ at present, so at present this is mostly of interest to people working on improving hardware support.
Raspberry Pi 2 Model B Support?
Hello, FreeBSD is already on the Pi 2. Does OpenBSD 6.3 Support Raspberry Pi 2 Model B? Many Thx.

It is like a small island in an ocean of compromised software. Considering the number of exploits, backdoors and other firmware hacks in the wild (from both our governments and theirs), there really isn't much software left one can trust. If OpenBSD ever runs blobs, then there will be nothing left standing between us and the spooks. Blobs are perfect vessels for military technology. Equation Group ring a bell? One can not overstate the importance of standing by this principle. We must preserve these islands of security and openness. Without them we are at the mercy of not just our spooks, but all of them.

It's no different on the 2 than the original pi (same GPU/boot mechanism), but there is a project https://github.com/jncronin/rpi-boot which claims to be an alternative second-stage so perhaps it's possible that way.. First-stage bootloader is pre-programmed on the board. It loads the second- stage from SD card to the GPU and starts it. Second-stage bootloader runs on the gpu and loads start.elf (3rd stage) which contains gpu firmware (actually an RTOS which stays running) and which boots the main cpu. The RTOS has a message passing interface used for GPU access from the main OS, so one area of concern is how that handles malicious inputs. It sets up a memory split between GPU/CPU at boot but it's unclear how this is protected if at all; one important question is whether the code running on the GPU can access CPU memory after boot. There are scary things on common x86 systems too of course (network-accessible management processors running crappy software sitting on the same i2c bus as the EEPROM containing the BIOS; a payload inserted to code running in SMM would have a lot of access ...) For all of the posts with people asking about OpenBSD on the rpi I don't think I've seen a single one along the lines of I've done x and y (see this diff) but am stuck on getting z to work, I only remember ones that are more like can somebody port OpenBSD to the rpi for me. (Hint: if somebody is willing/ able/interested/stubborn enough to do this, posts like that will be totally off the radar).
Re: Raspberry Pi 2 Model B
Hello I haven't know that Raspberry Pi is so closed that it requires closed source blob to even boot. Thanks for responses. I am not going to buy Raspberry Pi 2 any more (or at least when blob will be open source). Have a good day.
Re: Raspberry Pi 2 Model B
If you really do want a BSD on your Pi, use FreeBSD, I've successfully installed FreeBSD on my original Pi. There has been a line drawn by the OpenBSD developers, for the reasons they have stated and its a fair decision and unless someone else wants to fork OpenBSD, we'll just have to accept it for what it is. As much as I'd like OpenBSD, its not going to happen. FreeBSD is a perfectly acceptable alternative to OpenBSD, although it has its differences its still better than a Linux variant. regards,Jayton

Raspberry Pi 2 Model B
Hi New version of Raspberry Pi is announced. Its SoC have four cores in Cortex-A7 microarchitecture so it is compatible with ARMv7. It also have 1 GB of RAM. Have the same GPU as its predecessor: VideoCore IV 3d. For some time GPU have open documentation and open (BSD licence) driver in Linux world. Price is still $35. It should be electrically compatible with predecessor and have the same dimensions. Are you going to support this hardware in OpenBSD?

Re: Raspberry Pi 2 Model B
There is a difference in code that runs in the cpu of your hard drive and code running in your CPU to allow talking to the hard drive. From what I recall, the RPI GPU stuff falls into the second category, whereas hard drives normally falls into the first. One of them is just stuff that makes the drive work, and the other is what openbsd calls a blob. You can't realistically prevent code from running inside the hard drive cpu (firmware loaded or not), and for most of the usage it just is how stuff is done today. What you can do realistically is to prevent untrusted binary code from running on the same cpu where your openbsd kernel runs, and that is where OpenBSD has drawn the line. 2015-02-02 16:43 GMT+01:00 Einfach Jemand rru@gmail.com: Am 02.02.2015 um 15:20 schrieb Janne Johansson: But it still requires a blob to actually run, does it not?
