Mostly a fixup for the emac1 node, which I am unable to test. https://forum.armbian.com/topic/53058-banana-pi-bpi-m4-zero-sun50i-h618-emac1-internal-phy-not-detected-%E2%80%9Cno-phy-found%E2%80%9D/ Signed-off-by: Patrick Yavitz <[email protected]>

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.

Timestamp: 2025-03-31T22:20:48.475Z
Learning: For the Armbian build project, maintaining consistency with existing patches across U-Boot versions (such as between 2025.01 and 2025.04) is prioritized over refactoring individual patches for code improvements.

Learning: When porting patches between U-Boot versions (like from 2025.01 to 2025.04), rpardini prefers to maintain patches as-is rather than introducing refactoring changes, even when potential improvements are identified. This approach prioritizes consistency and reduces the risk of introducing new issues.

Timestamp: 2025-06-24T10:08:40.313Z
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: In the Armbian build system, BOOTPATCHDIR can contain board-specific subdirectories (e.g., board_orangepi5pro) for applying patches to specific boards only. The framework automatically checks if such board-specific subdirectories exist for the board being built and applies those patches accordingly.

Learning: The Armbian build system references Linux kernel versions in the form "tag:v6.14.4" in the KERNELBRANCH variable, even when point release tags might not be directly visible in the upstream repository in the same form.

Timestamp: 2025-07-17T04:12:33.125Z
Learning: In the Armbian build system, board configuration files (*.conf) follow a project standard of not including shebang lines, even though they contain bash code and are sourced by the build system. This is an established Armbian convention that individual contributors are expected to follow, and changes to this standard would require broader project maintainer approval.

Learning: In the Armbian build system, for recurring maintenance tasks like kernel version bumping, TODO comments should use generic version formats (e.g., "MAJOR.MINOR-rc1") rather than specific version numbers (e.g., "6.17-rc1") to avoid the need for frequent comment updates that would create unnecessary maintenance overhead.

Learning: In config/bootscripts/boot-sunxi.cmd the variable name `align_overlap_oboe_avoidance` intentionally uses the acronym “OBOE” (Off-By-One Error); it is not a typo and should not be renamed.

Learning: The 4KB (0x1000) boundary used for device tree size calculations in U-Boot scripts is specific to how the `fdt resize` command works internally and should remain hardcoded rather than being tied to adjustable alignment variables.

Learning: In Armbian board configuration files (.csc), 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.

Learning: For AIC8800 Bluetooth devices in Armbian board configurations, systemd service configurations intentionally use Type=idle and boot delays because there is no compatibility to load AIC8800 bluetooth in mainline kernel. These delays and service timing are necessary workarounds for hardware limitations rather than performance issues.

Learning: Armbian build framework extensions are NOT designed to run standalone but are called by the supervisor. The framework provides environment variables like USERPATCHES_PATH and SDCARD, and commands are executed with protection via run_host_command_logged and chroot_sdcard functions that use bash -e -o pipefail.

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.
