- on top of Joshua Riek's DT, add: - GPU - NPU - i2c5 (40-pin) - saradc - tsadc (thermals) - pwm2 / tacho / cooling fan - sys-led - usb2 otg (for flashing / UMS - microusb port) - USB3 ports (via usb hub on carrier board) - hdmi0 & hdmi0 audio & vop - uart1 (40-pin)
- boot order: NVMe -> MMC - GMAC works - nvme works - `ums` et al working - usb3 ports (on carrier board) work - DT is copy (not symlink) from kernel DT due to NPU nodes
- no need for vendor u-boot, as mainline can boot vendor kernel fine - update comments with hardware pin references - mainline boot order: NVMe -> USB -> eMMC

Learning: In the Armbian build system, rk3576 boards consistently use BOARDFAMILY="rk35xx" for both vendor and edge kernel targets. 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.

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.

Timestamp: 2025-09-14T06:29:18.958Z
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, kernel patches (e.g., in patch/kernel/archive/sunxi-6.18/patches.armbian/) contain device tree overlays and other code that have existed for years and are maintained/ported across kernel versions. When reviewing PRs that modify these patch files, focus on the actual changes being made (e.g., Makefile fixes, new additions) rather than reviewing the entire existing content within the patch as if it were new code. The patch file contents are existing, stable code unless explicitly modified in the PR diff.

Learning: In the Armbian build system, vendor kernel forks can use "vendor-edge" branch naming for bleeding-edge or pre-release vendor kernels, as demonstrated in config/sources/families/k3.conf. The typical vendor branch naming pattern is: "vendor" or "vendor-rt" for stable vendor releases, and "vendor-edge" for bleeding-edge/pre-release vendor versions. The "edge" naming without "vendor-" prefix is reserved for mainline kernel branches.

Learning: In the Armbian build repository, when introducing new requirements or checks (like the board assets verification workflow), the project prefers an initial educational-only period where violations post helpful PR comments and warnings but don't block merges. This allows contributors to become familiar with new requirements before enforcement is enabled (typically after ~6 months).

Learning: When reviewing kernel or u-boot version bump PRs in the Armbian build system, check if patches existed in previous kernel version directories (e.g., sunxi-6.12, sunxi-6.13) before describing them as new features. If a patch and the majority of its contents existed previously with no major functionality changes, focus the review on the actual changes: the version bump itself and patch compatibility adjustments. Don't describe existing patches being ported/maintained across versions as new features or drivers—this is misleading. The patches are existing code being re-aligned to work with the new upstream version.

Timestamp: 2025-11-08T06:39:24.527Z
Learning: In Armbian's Rockchip vendor kernel branches (rk35xx-vendor), device tree files may not require the same headers as mainline Linux. For example, input key definitions like KEY_BACK and KEY_VOLUMEUP may be handled differently in BSP kernels and don't necessarily need explicit includes like <dt-bindings/input/input.h> that would be required in mainline kernel device trees.

Learning: In RK3576 device tree files (like rk3576-nanopi-r76s.dts), the serial0 alias is already defined in the upstream kernel's rk3576.dtsi base file, so board-specific DTS files do not need to redeclare it when enabling &uart0 for serial console.

Learning: In the Armbian build system, the write_uboot_platform() function implementations follow different patterns across Rockchip family files. 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.

Learning: For the RV1106 family in Armbian (config/sources/families/rockchip-rv1106.conf), udev.children-max=1 is set in the kernel boot parameters to prevent early-boot OOM errors. The RV1106 has a single-core CPU, so parallelism in udev child processes provides no practical benefit. Testing higher values is impractical due to the difficulty of monitoring at this early boot stage.

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 for SpacemiT U-Boot patches (patch/u-boot/legacy/u-boot-spacemit-k1/), alignment with mainline U-Boot behavior is prioritized. For example, in boot mode handling, leaving devnum unchanged in the default case (when devtype is cleared) follows mainline conventions rather than explicitly clearing it to handle edge cases.

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).

This implementation aligns with mainline U-Boot conventions for the SpacemiT platform and has been verified to work correctly by the maintainer.

This provides a two-step workflow: configure using menuconfig, then build, with better transparency and control over configuration changes.

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: In Armbian's wireless driver configuration, CONFIG_RK_WIFI_DEVICE_* options are Rockchip-specific device registration settings, while CONFIG_WLAN_UWE* are the actual cross-platform driver modules for UWE5622 wireless chips. The UWE5622 chip (manufactured by Unisoc/Spreadtrum) is used on multiple Allwinner boards including Orange Pi Zero 2/2W/3 and Orange Pi 3 LTS, so CONFIG_WLAN_UWE5621/5622 along with Unisoc infrastructure options (CONFIG_SPARD_WLAN_SUPPORT, CONFIG_SC23XX, CONFIG_UNISOC_WIFI_PS, CONFIG_WCN_BSP_DRIVER_BUILDIN) are correct in sunxi64 kernel configs.

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.

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, kernel configurations prioritize broad hardware compatibility over optimization concerns. Even when including numerous legacy/obsolete drivers causes technical issues like increased initramfs size and slower enumeration, the project philosophy is to "appease the masses" by ensuring maximum device compatibility rather than optimizing for specific use cases.

Learning: In the Armbian build framework, scripts/config correctly handles kernel configuration option names both with and without the CONFIG_ prefix, so opts_m+=("CONFIG_RTL8822CS") and opts_m+=("RTL8822CS") are both valid and will work correctly.

Learning: In Linux kernel configuration, some `=y` (builtin) options are infrastructure or feature flags that enable subsystems or features for modular drivers, rather than directly compiling code into the kernel. For example, in Armbian wireless configs, options like CONFIG_SPARD_WLAN_SUPPORT=y, CONFIG_SC23XX=y, CONFIG_WCN_BSP_DRIVER_BUILDIN=y, CONFIG_UNISOC_WIFI_PS=y are module infrastructure/feature enablers, while the actual drivers (CONFIG_WLAN_UWE5621=m, CONFIG_WLAN_UWE5622=m) remain as loadable modules. These infrastructure options don't cause kernel bloat.

Learning: The rewrite-patches tool (REWRITE_PATCHES=yes) in the Armbian build system can inadvertently introduce semantic changes when the u-boot/kernel git base revision differs from expected state. The tool applies patches, commits them, and re-exports them using git format-patch, which can cause the re-exported patch to reflect the base revision's state rather than preserving the original patch intent. This is particularly problematic for device tree changes like interrupt specifications. The tool currently lacks validation mechanisms to detect such semantic drift, and affected patches must be manually corrected after rewriting.

1-104: LGTM!Well-structured device tree header with proper SPDX license, model/compatible strings, aliases, chosen node, and root-level peripherals (fan, LEDs, regulators, HDMI connector). The regulator supply chains are correctly defined.
106-303: LGTM!CPU, GPU, GMAC, and I2C configurations are correctly structured. The RTL8211F Ethernet PHY reset timing values are appropriate, and regulator references are consistent throughout.
305-903: LGTM!Comprehensive thermal management with appropriate trip points, PCIe domain assignments, pinctrl definitions, and PMIC regulator tree. The USB configuration correctly sets host0 as peripheral (for OTG/maskrom) and host1 as host (for carrier board hub).

1-96: LGTM!Well-structured U-Boot defconfig for RK3588 with appropriate feature enablement. Using
CONFIG_TARGET_ROCK5B_RK3588as a base target is a common pattern for RK3588 boards in mainline U-Boot when a dedicated board target doesn't exist. The device tree paths correctly reference the Mixtile-specific DTB, and essential features (SPL, ATF, FIT, PCIe, NVMe, USB gadget) are properly enabled.config/boards/mixtile-core3588e.csc (3)
33-50: LGTM!The mainline U-Boot override function is well-structured with proper blob mapping and the correct
write_uboot_platformimplementation usingstatus=noneper Armbian standards. Disabling Plymouth is a sensible choice for this board.
52-60: LGTM!Boot order customization is appropriate for this board's hardware configuration (mmc1 first for SD card boot priority during development, then NVMe for production use).
38-38: Update BOOTBRANCH to use v2026.01-rc3 instead of v2026.01-rc4.The version v2026.01-rc4 is not documented in the official U-Boot release schedule. The most recent officially released candidate is v2026.01-rc3 (November 24, 2025). The stable v2026.01 release is scheduled for January 5, 2026.

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.Learnt from: EvilOlaf Repo: armbian/build PR: 8537 File: config/boards/qcom-robotics-rb5.conf:1-1 Timestamp: 2025-09-18T03:36:17.862Z Learning: In Armbian board configuration files, .wip and .conf extensions require BOARD_MAINTAINER to be present and contain at least one maintainer.

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 "current" and "edge" naming is reserved for mainline kernel branches.
