Today's Canoeboot 20250107 revision, which is the 8th revision in the Canoeboot
|
|
|
|
|
20250107 stable release series. The changelog on this page is written, relative
|
|
|
|
|
to the Canoeboot 20241207 release which was released on 7 December 2024.
|
|
|
|
|
|
|
|
|
|
This release, Canoeboot 20250107, is based on and in sync with the recent

Canoeboot is a free/libre BIOS/UEFI replacement on x86 and ARM, providing
|
|
|
|
|
boot firmware that initialises the hardware in your computer, to then load an
|
|
|
|
|
operating system (e.g. GNU+Linux). It is specifically a *coreboot distribution*,
|
|
|
|
|
like how Trisquel is a GNU+Linux distribution. It provides an automated
|
|
|
|
|
build system to produce coreboot ROM images with a variety of payloads such as
|
|
|
|
|
GNU GRUB or SeaBIOS, with regular well-tested releases to make coreboot as easy
|
|
|
|
|
to use as possible for non-technical users. From a project management perspective,
|
|
|
|
|
this works in *exactly* the same way as a Linux distro, providing a source-based
|
|
|
|
|
package manager (called cbmk) which patches sources and compiles coreboot images.
|
|
|
|
|
It makes use of [coreboot](https://www.coreboot.org/) for hardware initialisation,
|
|
|
|
|
and then a payload such as [SeaBIOS](https://www.seabios.org/SeaBIOS)
|
|
|
|
|
or [GNU GRUB](https://www.gnu.org/software/grub/) to boot your operating
|
|
|
|
|
system; on ARM(chromebooks), we provide *U-Boot* (as a coreboot payload).
|
|
|
|
|
Experimental x86 U-Boot support is also available.

Summarised list of changes
|
|
|
|
|
==========================

|
|
|
|
|
Board support
|
|
|
|
|
-------------
|
|
|
|
|
|
|
|
|
|
RP2530 devices now supported in `pico-serprog`, e.g. Raspberry Pi Pico 2.
|
|
|
|
|
|
|
|
|
|
We previously only supported the RP2040 devices, e.g. original Pi Pico. We
|
|
|
|
|
now support both RP2040 and RP2530. Images are provided in the same tarball.
|
|
|
|
|
|
|
|
|
|
The documentation has been updated, to reflect this improvement. Canoeboot also
|
|
|
|
|
now imports `picotool` which is now used to compile the UF2 binaries for
|
|
|
|
|
installation, when building them from `pico-sdk`.

Revision updates
|
|
|
|
|
----------------
|
|
|
|
|
|
|
|
|
|
In descending order from latest changes to earliest changes:
|
|
|
|
|
|
|
|
|
|
* Bumped SeaBIOS to revision 1602647f1 (7 November 2024). This brings in a
|
|
|
|
|
single change from upstream, that prevents the boot menu from being hidden
|
|
|
|
|
when `boot-menu-wait` is negative.
|
|
|
|
|
* Bumped GRUB to revision 6811f6f09 (26 November 2024). This brings in several
|
|
|
|
|
important fixes from upstream, most notably TPM2 key support, though we
|
|
|
|
|
don't yet actually enable it in the code as it's unused on all machines.
|
|
|
|
|
Minor fixes have been observed, e.g. graphical glitches fixed under certain
|
|
|
|
|
edge cases.
|
|
|
|
|
* Bumped flashprog to revision eb2c041 (14 Nov 2024). This brings in several
|
|
|
|
|
important fixes from upstream.
|
|
|
|
|

Feature changes
|
|
|
|
|
---------------
|
|
|
|
|
|
|
|
|
|
In descending order from latest changes to earliest changes:
|
|
|
|
|
|
|
|
|
|
* `util/nvmutil`: Show the same byte order, in the same grouping and
|
|
|
|
|
display format, as `hexdump -C`, so that the output is more intuitive when
|
|
|
|
|
the user runs e.g. `./nvm gbe.bin dump`
|
|
|
|
|
* `lib.sh`: Support `reinstall` on Fedora dnf. Use it by running
|
|
|
|
|
the `./mk dependencies fedora re` command.
|
|
|
|
|
* `lib.sh`: Support `--reinstall` on Debian apt-get, when running
|
|
|
|
|
the `./mk dependencies debian` command. You can
|
|
|
|
|
use: `./mk dependencies debian --reinstall`
|
|
|
|
|
* `rom.sh`: Support setting `payload_grubsea="y"` on a board's `target.cfg`
|
|
|
|
|
file when compiling, so that GRUB is the primary payload. This is not enabled
|
|
|
|
|
on any boards, nor will it be, on release images, but the user can do it
|
|
|
|
|
themselves when compiling from source.

Bug fixes
|
|
|
|
|
---------
|
|
|
|
|
|
|
|
|
|
Several fixes were made to prevent build errors on the latest Debian Sid
|
|
|
|
|
and Arch Linux, as of 6 January 2025. Fedora 41 was also tested, fixing
|
|
|
|
|
various issues.
|
|
|
|
|
|
|
|
|
|
The following bug fixes have been merged (in descending order from the latest
|
|
|
|
|
changes to the earliest changes):
|
|
|
|
|
|
|
|
|
|
* `lib.sh`: Python versions are detected using Python's own built-in tuple,
|
|
|
|
|
instead of relying on the `--version` argument, because the tuple is more
|
|
|
|
|
consistent across various distros, whereas some distros might modify the
|
|
|
|
|
output of `--version` to include their own branding, which could have messed
|
|
|
|
|
up the way our build system was using `awk`.
|
|
|
|
|
* `lib.sh`: Properly set up `python` in the `PATH` directorier, by creating
|
|
|
|
|
a temporary link to the correct Python version, where detected. Python 3
|
|
|
|
|
is the only python on most distros now, but we still occasionally encounter
|
|
|
|
|
setups where the user has `python` as v2.x and has `python3` in PATH for
|
|
|
|
|
Python v3.x; in this latter scenario, the build system corrects for it so
|
|
|
|
|
that `python` is temporarily v3.x while images are being compiled. Several
|
|
|
|
|
parts of the build system do use Python quite heavily, and it is *always*
|
|
|
|
|
Python 3.
|
|
|
|
|
* `submodule/grub`: Use codeberg as the primary mirror, instead of the GNU
|
|
|
|
|
mirror, because the GNU mirror is often slow. This is done specifically
|
|
|
|
|
for the `gnulib` GRUB submodule.
|
|
|
|
|
* `util/nvmutil`: Describe what the program does, in help output. The lack
|
|
|
|
|
of such info is considered a bug, because lack of documentation is a bug.
|
|
|
|
|
* `util/nvmutil`: Proper `PREFIX` and `DESTDIR` handling in the Makefile.
|
|
|
|
|
The default prefix is now `/usr/local`, as is correct and righteous; it
|
|
|
|
|
was previously `/usr`. All variables are now properly honoured,
|
|
|
|
|
namely: `DESTDIR`, `PREFIX`, `INSTALL`, `CC` and `CFLAGS` - the user can
|
|
|
|
|
now set custom variables, when compiling.
|
|
|
|
|
* Fixed several errors produced by `shellcheck` on the build system.
|
|
|
|
|
* Added `libuuid-devel` to Fedora dependencies.
|
|
|
|
|
* flashprog: Disable `-Werror` on builds, to prevent over-zealous compilers
|
|
|
|
|
from yielding errors on mere warnings. This is a preventative bug fix,
|
|
|
|
|
because no errors had yet been observed.
|
|
|
|
|
* Debian dependencies: Replaced `liblz4-tool` with `liblz4-dev`, for
|
|
|
|
|
Debian Trixie/Sid. The same config still works for Debian Bookworm.
|
|
|
|
|
* `u-boot`: Imported a fix from upstream, that prevents a build error when
|
|
|
|
|
compiling with Swig 4.3.0, because the calling convention changed on one
|
|
|
|
|
of the functions that U-Boot's build system uses. Specifically,
|
|
|
|
|
the `SWIG_AppendOutput` is used now. The way this fix works means that there
|
|
|
|
|
are no behaviour changes, when compiling on an older machine with,
|
|
|
|
|
say, Swig 4.1.0 as used in Debian Bookworm, which is what Canoeboot currently
|
|
|
|
|
uses on this day, when compiling releases. We still want the build system
|
|
|
|
|
to work on newer distros.
|
|
|
|
|
* Use `command -v` instead of `which`, where the latter was previously used
|
|
|
|
|
in a few places on the build system. The `command -v` command is standard,
|
|
|
|
|
whereas `which` isn't. This is to
|
|
|
|
|
mitigate [which hunts](https://lwn.net/Articles/874049/).
|
|
|
|
|
* Added double quotes on several variables in the build system, to prevent
|
|
|
|
|
globbing.
|
|
|
|
|
* Removed auto-confirm options on distro dependencies scripts. This is to
|
|
|
|
|
prevent buggy distros from messing up the user's packages, because now it
|
|
|
|
|
will show a confirmation dialog when the package manager sees a conflict;
|
|
|
|
|
previously, the build system just said yes to everything, which reduced the
|
|
|
|
|
amount of user interaction. The idea is to annoy the user, rather than
|
|
|
|
|
break their machine, and this is only a mild annoyance.
|
|
|
|
|
* `trees`: Hack the `PATH` environmental variable to link GCC and GNAT, matching
|
|
|
|
|
them so that both versions are the same. This mitigates an issue on Debian
|
|
|
|
|
Trixie/Sid as of January 2025, whereby `gcc` is `gcc-14` while `gnat`
|
|
|
|
|
is `gnat-13` and also installs `gcc-13`; if this ids what the user has, GCC
|
|
|
|
|
is set to GCC 13 in `PATH`. The user can install `gnat-14` if they wish,
|
|
|
|
|
and the GNAT version is auto-matched in `PATH` instead, matching GCC. This
|
|
|
|
|
is only done when compiling the coreboot crossgcc toolchain, because GNAT
|
|
|
|
|
is required there and must match the GCC version.
|
|
|
|
|
* `dependencies/debian`: Changed `python3-distutils`
|
|
|
|
|
to `python3-distutils-extra`, so that dependencies can be installed on
|
|
|
|
|
Debian Trixie/Sid; the same config still works on Debian Bookworm.
|
|
|
|
|
* Added SPDX headers to various configuration files.
|
|
|
|
|
* `git.sh`: Re-initialise the `livepull` variable per-project and per-tree,
|
|
|
|
|
so that previous runs of it do not unpredictably affect the next, when
|
|
|
|
|
cloning upstream Git repositories.
|
|
|
|
|
* `lib.sh`: Safer exit when running `./mk dependencies` (don't rely on the
|
|
|
|
|
exit statuses of chained commands being zero).
|
|
|
|
|
* GRUB: Background images are loaded again from CBFS, instead of memdisk,
|
|
|
|
|
because otherwise GRUB prefers the memdisk one and adding one in CBFS
|
|
|
|
|
didn't change the background image, when users attempted this.
|
|
|
|
|
|
|
|
|
|
General code cleanup
|
|
|
|
|
--------------------
|
|
|
|
|
|
|
|
|
|
In descending order from the latest changes to the earliest changes:
|
|
|
|
|
|
|
|
|
|
* `util/nvmutil`: Make the GbE checksum of `0xBABA` a define, for clarity.
|
|
|
|
|
* `lib.sh`: cleaned up a few if statements
|
|
|
|
|
* `util/nvmutil`: Tidied up several `pledge` calls on OpenBSD (code quality
|
|
|
|
|
improvement).
