Add Google kano (Mr Chromebox) support - First full Chromebook port! by cwiggs · Pull Request #2133 · linuxboot/heads

cwiggs · 2026-06-24T02:59:12Z

This pull request adds support for the Acer Chromebook Spin 714 ("kano") board based on the MrChromebox coreboot fork (26.06), including CI integration, configuration files, and documentation updates. It also introduces a patch for musl compatibility in the MrChromebox fork, adds a new Linux kernel version (6.6.30), and documents TPM2 CR50 command support. The most important changes are grouped below:

Kano (Acer Chromebook Spin 714) board support:

Adds boards/kano/kano.config for Heads and Linux build configuration for the kano board.
Adds config/coreboot-kano.config_defconfig as a defconfig backup for kano, documenting non-default coreboot options.
Integrates kano into CircleCI: adds coreboot-mrchromebox as a seed, defines the kano build job, and documents its workflow. [1] [2] [3]
Documents kano's handling of the RTC century byte and why USE_PC_CMOS_ALTCENTURY must be unset for this board. [1] [2] [3]

MrChromebox coreboot fork integration:

Adds the MrChromebox coreboot fork (26.03) as a supported module in modules/coreboot, with commit hash pinning and submodule handling notes. [1] [2]
Documents and implements post-build application of the ME HAP bit for MrChromebox-based boards (e.g., kano) via ifdtool. [1] [2]

Build system and kernel updates:

Adds Linux kernel version 6.6.30 support for use by kano and other boards. [1] [2]
Adds a musl compatibility patch for MrChromebox coreboot's cbmem utility.

Documentation improvements:

Documents how to clone the repository with full history and repair shallow clones for reproducible builds.
Adds a section on CR50 TPM command limitations and Heads TPM2 command compatibility.
Expands documentation on defconfig backups for Chromebook boards and Heads-common coreboot options. [1] [2] [3]

Minor adjustments:

Updates the list of boards with specific coreboot options and clarifies configuration for Purism and QEMU boards. [1] [2]

These changes collectively enable official Heads support for the Acer Chromebook Spin 714 (kano), ensure compatibility with the MrChromebox fork, and improve build reproducibility and documentation for new contributors.

TODO before merge

Additional questions:

Confirm/infirm initrd/bin/kexec-save-default.sh: skip symlinks when finding crypttabfiles #2155 needed to boot NixOS
Any impact from ME being HAP disabled??

first review as I was there and saw work on this PR :)

I suggest you tart a thread under Matrix Heads channel. You must rebase the old PR on linuxboot/heads master, an dthen adapt coreboot config to your board. Following https://osresearch.net/Porting/ @cwiggs otherwise your experience might be really frustrating.

Absolutely. It builds from CI. I pushed progress forward since the last base (coreboot 4.22) was old and not trivial to adapt. Let me know how the testing goes. Feel free to cherry pick all commits or if you agree i can push the changes here but that would make us both co-authors of the port.

I just rebased off your branch, let me know if it looks good from that point of view. Looks like I also will need to rebase off main.

As far as flashing goes: I got the Suzy-Q "cable" (It's really just a small board with a male and female usb-c, you then use your own usb-c cable). And I have some good news and some bad news (I think?). I was able to get the suzy-q cable to read the rom, but verifying the backup seems to fail.

I've been using this mrchromebox guide to get the suzy-q device working with flashrom and then this heads wiki as well. Below are some notes I put together while I was attempting the flash:

Use Suzy-Q cable for flashing

Connect the USB-C end of the Suzy-Q cable to the CCD port on your ChromeOS device
(usually left USB-C port) and the USB-A end to your Linux device
Verify the cable is properly connected:
- ls /dev/ttyUSB*
- This command should return 3 items: ttyUSB0, ttyUSB1, and ttyUSB2.
- If not, then your cable is connected to the wrong port or is upside down.
  Adjust and repeat command until output is as expected.
Set the CCD state to open:
- echo "ccd open" | sudo tee -a /dev/ttyUSB0 > /dev/null

Questions:

When I run sudo flashrom -p raiden_debug_spi I'm getting a "Error: Programmer initialization failed" and "Target SPI bridge is disabled (is WP enabled?)". The mrchromebox guide does talk about disabling write-protection, but it seems to only be possible to do via a tool in ChromeOS (gsctool), or by disconnecting the laptops battery. Seems very likely write-protection is still on.
Looks like I was able to create a backup, but then when I verify it I get: "Verifying flash... FAILED at 0x01bc9254! Expected=0xb7, Found=0xb8, failed byte count from 0x00000000-0x01ffffff: 0x3e" Why is it not working?

Anyway I think next steps are to disconnect the battery and try these flashrom commands again. I don't want to proceed until the verify step works without error.

cwiggs · 2026-07-04T23:17:43Z

Well I disconnected the battery and am getting the same response from flashrom. Should I just continue with flashing heads?

Here are my notes:

Disconnect Battery to disable write-protection.

Remove The 9 screws.

* Use a smudger to take the back cover off. * Disconnect battery cable.

Put laptop back together.

Disable write-protection. mrchromebox guide

Plug laptop into power.
Plug in suzy-q cable.
echo "wp false" > /dev/ttyUSB0
echo "wp false atboot" > /dev/ttyUSB0
echo "ccd reset factory" > /dev/ttyUSB0

Tried the same flashrom commands to backup and verify above and got the same result of "Error: Programmer initialization failed" and "Verifying flash... FAILED at 0x0003e1c0! Expected=0x28, Found=0x68, failed byte count from 0x00000000-0x01ffffff: 0xe99" when verifying.

I also have a working branch for the wiki for heads. I'll get it up as a draft/WIP and then add to it.

Curious since you are a daily NixOS user, and that installation docs under https://osresearch.net are.... hmm. less then optimal to guide users into what is different requirements then UEFI, even though latest #2130 helped a lot fb+iso support, unless bugs found, most if not all linux distributions.

You didn't need #2155 ?

I was able to get my NixOS install working in Heads with a very simple change you can see here: https://gitlab.com/cwiggs/nix/-/commit/a7419c5511b45e0fa04590788bcb8309e12825e9

I didn't need #2155 and DUK still works without issues. I can also post a tree or files in /boot if that helps.

Interesting. My issue was not about installing grub, that did work. My issue pointing to #2155 being required was that when setting up a TPM DUK for a selected boot entry to become default, initramfs unpacking failed finding a valid crypttab in initramfs pointed by boot entry in grub (it was a symlink pointing to rootfs path which is not available from initramfs itself.

If you could describe your custom partitioning scheme, I would definitely be interested in it, mine was roughly described into #2155 linked issue #2154. NixOS installer (GUI) complies with basic custom partitioning even though it warns that /boot mount point is reserved. But yeah, From my understanding, NixOS expects /boot to be subdir of / from an installation standpoint.
