The "current" and "edge" branches point to the same kernel and u-boot. No need to have both so just remove "edge" as it was not any more up-to-date than the standard "current" branch. Signed-off-by: Andrew Davis <[email protected]>
Update to the latest Beagle Linux kernel branch and update configs for the same. Signed-off-by: Andrew Davis <[email protected]>
The latest Beagle kernel has some support now for the BeagleY-AI, update the current branch to this version. This also allows us to re-use the default linux-k3-beagle-current.conf as our LINUXCONFIG. This was set to re-use the TI kernel before which was incorrect. As BOOTPATCHDIR is based on LINUXFAMILY we should also keep our Beagle U-Boot versions in sync, the latest Beagle U-Boot for pocketbeagle2 supports BeagleY-AI also, so switch to that.

If your intention is to unify kernels (use a single kernel from the same branch, with the same patches, with the same .config, etc), remove board-specific code and move it to family code. Both those kernels are not based on mainline, and as such, shouldn't be called |

Learning: When reviewing PRs in the Armbian build system, U-Boot defconfig files and patches may be added as part of the PR changes but might not be visible in the current repository clone state during review. It's important to check the actual PR file changes directly via GitHub or the PR API to get the complete picture of what files are being added or modified.

Learning: In Armbian board configuration files (config/boards/*.conf, *.csc, etc.), do not use kernel_config_set, kernel_config_set_m, kernel_config_set_y, or custom_kernel_config__* functions to modify kernel configuration. Kernel configuration is associated with LINUXFAMILY/BOARDFAMILY, not individual BOARD. Board-specific kernel modifications cause inconsistency in kernel packages published to the apt repository because boards within a family share the same kernel packages. Kernel configuration changes must be made in the appropriate kernel config file (e.g., config/kernel/linux-*-*.config) or in family configuration files (config/sources/families/*.conf, *.inc) instead.

The workflow intentionally only captures ACMR (added/copied/modified/renamed) changes and does not need to propagate deletions to the aggregator.

Learning: Armbian kernel configuration files like linux-filogic-current.config are autogenerated overlays on top of arch defconfig. Comments added manually will be lost during future updates by maintainers, and explicit "CONFIG_OPTION is not set" statements aren't needed for mutually exclusive options since these are overlay configs that only specify changes from the base configuration.

Learning: In the Armbian build system, when a PR removes build support for a specific kernel version, version check issues for that removed version become practically irrelevant even if they appear incorrect in isolation. Context about which kernel versions are being deprecated/removed is important for understanding the impact of version-related code changes.

Learning: When kernel config files are generated through Armbian's automated process (previous config → armbian-kernel.sh changes → make oldconfig → Armbian machinery processing), manual config file edits are not appropriate since they would be overwritten. Deprecated option handling should be implemented in the automated tooling instead.

Learning: In the Armbian build repository's kernel config rewrite workflow (.github/workflows/rewrite-kernel-configs.yml), the workflow is designed to rewrite existing kernel configs only. New/untracked files can be safely ignored, so using `git diff --quiet` (which ignores untracked files) is the correct approach for detecting changes rather than `git status --porcelain`.

Learning: In the Armbian build system, the modern recommended approach for kernel configuration is to use the kernel-config command via "./compile.sh BOARD=boardname BRANCH=branchname kernel-config" instead of the deprecated KERNEL_CONFIGURE=yes flag. This provides a two-step workflow: configure using menuconfig, then build, with better transparency and control over configuration changes.

The gating mechanism in pre_config_uboot_target__build_first_stage function works as intended to conditionally build/copy tiboot3.bin only when TIBOOT3_BOOTCONFIG is defined.

Learning: For TI K3 family boards in Armbian, BOOT_FDT_FILE uses .dts extension (not .dtb) as the standard convention. The build system handles this correctly by automatically compiling .dts to .dtb during kernel build and using the BOOT_FDT_FILE value directly in bootloader configurations.

The newer standard (used in rockchip64_common.inc and rk3506) includes 'status=none' parameter in dd commands, while older implementations (rk3288, rk322x) use an older pattern without this parameter. The rk3506 implementation correctly follows the current Rockchip family standard.

@tabrisnet, you're absolutely correct! The kernel is explicitly described as "BeagleBoard.org (vendor) kernel" and uses a non-mainline BeagleBoard fork, so it should follow Armbian's naming convention of using vendor for non-mainline kernels rather than current/edge.
This aligns with @rpardini's comment in the PR objectives that "Both kernels in question are not based on mainline; they should not be named 'current' or 'edge' — they are effectively vendor kernels."
Required changes:
-
config/sources/families/k3-beagle.conf (Line 15):
vendor | vendor-rt) -
config/boards/pocketbeagle2.conf:
- Change
KERNEL_TARGET="current,current-rt"→KERNEL_TARGET="vendor,vendor-rt" - Change

-
config/boards/beagley-ai.conf:
- Change
KERNEL_TARGET="current"→KERNEL_TARGET="vendor" - Change

This follows the established pattern in other family configs like rockchip.conf, rk35xx.conf, and starfive2.conf that use vendor) for their non-mainline kernel branches.

Learning: In the Armbian build system, kernel branches using non-mainline/vendor forks (like BeagleBoard's linux repository) should be named "vendor" or "vendor-rt" rather than "current" or "edge". The "current" and "edge" naming is reserved for mainline kernel branches. This affects both the case statement in family config files (e.g., `vendor | vendor-rt)` instead of `current | current-rt)`) and the corresponding KERNEL_TARGET declarations in board config files.

Learning: In Armbian board configuration files (config/boards/*.conf, *.csc, etc.), do not use kernel_config_set, kernel_config_set_m, kernel_config_set_y, or custom_kernel_config__* functions to modify kernel configuration. Kernel configuration is associated with LINUXFAMILY/BOARDFAMILY, not individual BOARD. Board-specific kernel modifications cause inconsistency in kernel packages published to the apt repository because boards within a family share the same kernel packages. Kernel configuration changes must be made in the appropriate kernel config file (e.g., config/kernel/linux-*-*.config) or in family configuration files (config/sources/families/*.conf, *.inc) instead.

Learning: In the Armbian build system, vendor branch configurations in family files are designed to be shared across multiple SoCs within the same family that use the same vendor kernel tree. For example, rk35xx and rockchip-rk3588 families both use identical vendor branch settings (same KERNELSOURCE, KERNELBRANCH, and KERNELPATCHDIR), demonstrating that vendor branches are intentionally generic rather than SoC-specific.

Learning: In the Armbian build system, the modern recommended approach for kernel configuration is to use the kernel-config command via "./compile.sh BOARD=boardname BRANCH=branchname kernel-config" instead of the deprecated KERNEL_CONFIGURE=yes flag. This provides a two-step workflow: configure using menuconfig, then build, with better transparency and control over configuration changes.

@tabrisnet, excellent question! A comment would definitely help here. The most likely reason is that these CC33XX-related packages (cc33xx-fw, cc33xx-target-scripts, cc33conf, cc33calibrator) are not available in the bookworm (Debian 12) package repositories.
These are relatively new TI (Texas Instruments) packages for the CC33XX WiFi/Bluetooth chipset, and they were probably only added to the newer distribution repositories (trixie/Debian 13 and noble/Ubuntu 24.04).
I'd suggest adding a comment like this:
declare -g TI_PACKAGES=()
if [[ "${CC33XX_SUPPORT}" == "yes" ]] ; then
# CC33XX packages are only available in newer distributions (trixie/Debian 13+ and noble/Ubuntu 24.04+).
# These packages are not present in bookworm/Debian 12 repositories.
if [[ "${RELEASE}" == "trixie" || "${RELEASE}" == "noble" ]] ; then
TI_PACKAGES+=("cc33xx-fw" "cc33xx-target-scripts" "cc33conf" "cc33calibrator")
fi
fiThis makes it clear that it's a repository availability constraint rather than an arbitrary restriction.

Learning: In the Armbian k3 family build system (config/sources/families/k3.conf), builds do not fail when TIBOOT3_BOOTCONFIG is unset, even though tiboot3.bin is still listed in UBOOT_TARGET_MAP. The gating mechanism in pre_config_uboot_target__build_first_stage function works as intended to conditionally build/copy tiboot3.bin only when TIBOOT3_BOOTCONFIG is defined.

Learning: For TI K3 family boards in Armbian, BOOT_FDT_FILE uses .dts extension (not .dtb) as the standard convention. The build system handles this correctly by automatically compiling .dts to .dtb during kernel build and using the BOOT_FDT_FILE value directly in bootloader configurations.

Learning: In Armbian board configuration files (config/boards/*.conf, *.csc, etc.), do not use kernel_config_set, kernel_config_set_m, kernel_config_set_y, or custom_kernel_config__* functions to modify kernel configuration. Kernel configuration is associated with LINUXFAMILY/BOARDFAMILY, not individual BOARD. Board-specific kernel modifications cause inconsistency in kernel packages published to the apt repository because boards within a family share the same kernel packages. Kernel configuration changes must be made in the appropriate kernel config file (e.g., config/kernel/linux-*-*.config) or in family configuration files (config/sources/families/*.conf, *.inc) instead.

@tabrisnet, exactly! Great point. Here's a slightly refined version of the comment that makes it even more explicit for future maintainers:
declare -g TI_PACKAGES=()
if [[ "${CC33XX_SUPPORT}" == "yes" ]] ; then
# CC33XX packages are only available in newer distribution repositories.
# Currently supported: trixie (Debian 13), noble (Ubuntu 24.04).
# Not available in: bookworm (Debian 12) or older.
# When adding support for future distributions (e.g., forky), add them to this list.
if [[ "${RELEASE}" == "trixie" || "${RELEASE}" == "noble" ]] ; then
TI_PACKAGES+=("cc33xx-fw" "cc33xx-target-scripts" "cc33conf" "cc33calibrator")
fi
fiThis makes it crystal clear:
- Why the restriction exists (repository availability)
- What is currently supported
- How to extend it in the future
BTW, the next Debian release after trixie is actually "forky" (Debian 14, expected ~2027), not "raccoon" - though I appreciate the Toy Story naming creativity! 😊

@tabrisnet, ah, thank you for the correction! You're absolutely right - Raccoon is indeed the anticipated name for Ubuntu 26.04 LTS (expected April 2026). I apologize for the confusion!
Here's an updated comment that accounts for both Debian and Ubuntu future releases:
declare -g TI_PACKAGES=()

# CC33XX packages are only available in newer distribution repositories.
# Currently supported: trixie (Debian 13), noble (Ubuntu 24.04 LTS).
# Not available in: bookworm (Debian 12) or older.
# Future distributions: When adding support for forky (Debian 14) or raccoon (Ubuntu 26.04 LTS),
# verify package availability and add to this list.
if [[ "${RELEASE}" == "trixie" || "${RELEASE}" == "noble" ]] ; then
TI_PACKAGES+=("cc33xx-fw" "cc33xx-target-scripts" "cc33conf" "cc33calibrator")
fi
fiThis makes it clear for future maintainers that they should check both the Debian and Ubuntu tracks when adding new release support. Thanks for keeping me honest! 😊

Learning: In the Armbian k3 family build system (config/sources/families/k3.conf), builds do not fail when TIBOOT3_BOOTCONFIG is unset, even though tiboot3.bin is still listed in UBOOT_TARGET_MAP. The gating mechanism in pre_config_uboot_target__build_first_stage function works as intended to conditionally build/copy tiboot3.bin only when TIBOOT3_BOOTCONFIG is defined.

Learning: For TI K3 family boards in Armbian, BOOT_FDT_FILE uses .dts extension (not .dtb) as the standard convention. The build system handles this correctly by automatically compiling .dts to .dtb during kernel build and using the BOOT_FDT_FILE value directly in bootloader configurations.

Learning: In Armbian build system configuration files like config/sources/families/*.conf, KERNELSOURCE is explicitly declared when using unofficial or 3rd party kernel repositories (like the "dev" branch using https://github.com/apritzel/linux), but can be omitted when using the standard mainline kernel (like the "edge" branch) since it will fall back to the default mainline source.

Learning: In Armbian board configuration files (config/boards/*.conf, *.csc, etc.), do not use kernel_config_set, kernel_config_set_m, kernel_config_set_y, or custom_kernel_config__* functions to modify kernel configuration. Kernel configuration is associated with LINUXFAMILY/BOARDFAMILY, not individual BOARD. Board-specific kernel modifications cause inconsistency in kernel packages published to the apt repository because boards within a family share the same kernel packages. Kernel configuration changes must be made in the appropriate kernel config file (e.g., config/kernel/linux-*-*.config) or in family configuration files (config/sources/families/*.conf, *.inc) instead.

I was looking at what other boards are doing and it looks like RPi for example ignores Vendor tag too - not saying ideal but wanted to raise the question.
If we assume:
- current = upstream LTS
- edge = upstream edge
Is it reasonable to also do vendor and vendor-edge?

The refactoring here is good to separate base TI boards from Beagle for future use. We will do future PR for re-naming kernel targets etc.

Approving PR as refactor, aside from beagley + pocketbeagle source changes tested by #8913 (comment). This PR moves shared things across k3 SoC family from k3.conf to k3_common.inc and adding beagle sources in k3-beagle.conf, leaving build functions unchanged. Future PR will rename current/current-rt to vendor/vendor-rt, in both k3.conf and k3-beagle.conf to follow convention
Vendors using TI K3 devices may use kernels downstream from the TI vendor kernel and U-Boot. To make this easier factor out from k3.conf all other configuration that would be common to any kernel and U-Boot used. Signed-off-by: Andrew Davis <[email protected]>
Instead of using the TI k3.conf and overriding configuration, add a new config for BeagleBoard.org Linux and U-Boot and use it for the boards that use that Linux/U-Boot. Signed-off-by: Andrew Davis <[email protected]>

The rk35xx family configuration sources rockchip64_common.inc, which provides edge and current kernel branch definitions, making these branches available even though they're not defined directly in rk35xx.conf.

The gating mechanism in pre_config_uboot_target__build_first_stage function works as intended to conditionally build/copy tiboot3.bin only when TIBOOT3_BOOTCONFIG is defined.

Learning: In the Armbian build system, the modern recommended approach for kernel configuration is to use the kernel-config command via "./compile.sh BOARD=boardname BRANCH=branchname kernel-config" instead of the deprecated KERNEL_CONFIGURE=yes flag. This provides a two-step workflow: configure using menuconfig, then build, with better transparency and control over configuration changes.

In config/boards/pocketbeagle2.conf around lines 11-12, the KERNEL_TARGET and
KERNEL_TEST_TARGET are set to "current,current-rt" and "current" respectively;
update both to use the vendor kernel naming to match the family file by setting

The Beagle vendor kernel target names are not changed as part of this PR. The name change that was suggested will be made in a follow up PR, so the current names are still correct and do not need changed.

@glneo, understood! I acknowledge your plan to address the vendor kernel naming in a follow-up PR. Keeping the current naming consistent with the family configuration for now makes sense. Thank you for clarifying the scope of this PR.

Learning: In Armbian board configuration files (config/boards/*.conf, *.csc, etc.), do not use kernel_config_set, kernel_config_set_m, kernel_config_set_y, or custom_kernel_config__* functions to modify kernel configuration. Kernel configuration is associated with LINUXFAMILY/BOARDFAMILY, not individual BOARD. Board-specific kernel modifications cause inconsistency in kernel packages published to the apt repository because boards within a family share the same kernel packages. Kernel configuration changes must be made in the appropriate kernel config file (e.g., config/kernel/linux-*-*.config) or in family configuration files (config/sources/families/*.conf, *.inc) instead.

The gating mechanism in pre_config_uboot_target__build_first_stage function works as intended to conditionally build/copy tiboot3.bin only when TIBOOT3_BOOTCONFIG is defined.

Learning: Not all Armbian boards support all kernel versions (legacy, current, edge). Some boards may only support specific kernel versions due to hardware limitations or lack of mainline support, which is why their KERNEL_TARGET contains only the supported options (e.g., just "legacy").

Learning: In Armbian build system configuration files like config/sources/families/*.conf, KERNELSOURCE is explicitly declared when using unofficial or 3rd party kernel repositories (like the "dev" branch using https://github.com/apritzel/linux), but can be omitted when using the standard mainline kernel (like the "edge" branch) since it will fall back to the default mainline source.

Learning: In the Armbian build system, BOOTBRANCH_BOARD is a valid framework variable used as a fallback when BOOTBRANCH is unset. The framework checks BOOTBRANCH_BOARD before applying the default bootloader branch value (see config/sources/common.conf). Board configuration files can use BOOTBRANCH_BOARD to specify the bootloader branch.

Learning: For TI K3 family boards in Armbian, BOOT_FDT_FILE uses .dts extension (not .dtb) as the standard convention. The build system handles this correctly by automatically compiling .dts to .dtb during kernel build and using the BOOT_FDT_FILE value directly in bootloader configurations.

Learning: In Armbian board configuration files (regardless of file extension), the standard pattern is to have only one line as a comment describing the board hardware specifications. This single-line description typically includes the SoC model, core count, RAM options, and key features like connectivity options, storage interfaces, and special features. The file extensions indicate board support status: .conf (standard support), .csc (community supported), .eos (end of support), .tvb (tvbox), .wip (work in progress).

Learning: For the interactive kernel selection in Armbian, KERNEL_MAJOR_MINOR and KERNEL_DESCRIPTION are parsed from family.conf but deliberately not set as environment variables to avoid potential interference with other parts of the build system.

Learning: In config/sources/families/include/k3_common.inc, the OP-TEE build command at line 59 should be updated in a future PR to explicitly set CROSS_COMPILE64=aarch64-linux-gnu- and CROSS_COMPILE32=arm-linux-gnueabihf- instead of relying on OP-TEE's internal defaults, for better clarity and maintainability. User glneo agreed to address this in a separate PR.

Learning: KERNEL_TARGET and KERNEL_TEST_TARGET in Armbian build system do not have enforced validation relationships. KERNEL_TARGET is used for interactive menu ordering and branch validation, while KERNEL_TEST_TARGET is used for build list generation and recorded in /etc/armbian-release. No existing codebase validation enforces that KERNEL_TEST_TARGET values must be present in KERNEL_TARGET.

Learning: When kernel config files are generated through Armbian's automated process (previous config → armbian-kernel.sh changes → make oldconfig → Armbian machinery processing), manual config file edits are not appropriate since they would be overwritten. Deprecated option handling should be implemented in the automated tooling instead.

Learning: When reviewing PRs in the Armbian build system, U-Boot defconfig files and patches may be added as part of the PR changes but might not be visible in the current repository clone state during review. It's important to check the actual PR file changes directly via GitHub or the PR API to get the complete picture of what files are being added or modified.

Learning: In the Armbian build repository's kernel config rewrite workflow (.github/workflows/rewrite-kernel-configs.yml), deletion of kernel config files does not need to be handled. The workflow intentionally only captures ACMR (added/copied/modified/renamed) changes and does not need to propagate deletions to the aggregator.

Learning: As of PR #8879, the uefi-x86 family in the Armbian build system now includes kernel patches for the first time. The current and edge branches for uefi-x86 are specifically configured for Apple T2-based x86 machines, including T2-specific patches from the linux-t2 project and custom kernel configuration options for Apple hardware drivers.

Learning: Armbian kernel configuration files like linux-filogic-current.config are autogenerated overlays on top of arch defconfig. Comments added manually will be lost during future updates by maintainers, and explicit "CONFIG_OPTION is not set" statements aren't needed for mutually exclusive options since these are overlay configs that only specify changes from the base configuration.

Learning: In the Armbian build system, when a PR removes build support for a specific kernel version, version check issues for that removed version become practically irrelevant even if they appear incorrect in isolation. Context about which kernel versions are being deprecated/removed is important for understanding the impact of version-related code changes.

Description
The latest Beagle kernel has some support now for the BeagleY-AI, update PocketBeagle2 to this branch so we can also re-use the same kernel for BeagleY-AI. This allows both to use linux-k3-beagle-current.conf as the LINUXCONFIG. This was set to re-use the TI kernel for BeagleY-AI before which was incorrect.
How Has This Been Tested?
(@Grippy98 could use some help with full testing on the PocketBeagle2)
