- Switched to the binman-atf-mainline scenario with the same rkbin DDR blob
rk3399_ddr_933MHz_v1.25.bin (TPL blob, as in the old working loader). DRAM init is correct, full
4 GB visible, Linux boots.
- U-Boot and DTS updated to v2026.01-rc5. Added MDIO/PHY node and phy-handle in rk3399-kobol-
helios64.dts, fixing “mdio node is missing”. Disabled i2s2 in the U-Boot DT to avoid rockchip-
i2s ... Could not register PCM.
- boot_targets in U-Boot config shortened (mmc1, scsi0, usb0, pxe, dhcp) to avoid env_buf ... too
small; however, the last built binary still shows the warning (needs rebuild with the shortened
list or enlarging the buffer).
- Boot flow: bootstd scans SD (mmc0) and eMMC (mmc1); SD boot works even without mmc0 in
boot_targets.
- Other changes: defconfig has CONFIG_ROCKCHIP_EXTERNAL_TPL=y to use the external DDR blob.
Boots.

Purpose of This Repository
The Armbian Linux Build Framework creates customizable OS images based on Debian or Ubuntu for single-board computers (SBCs) and embedded devices.
It builds a complete Linux system including kernel, bootloader, and root filesystem, giving you control over versions, configuration, firmware, device trees, and system optimizations.
The framework supports native, cross, and containerized builds for multiple architectures (x86_64, aarch64, armhf, riscv64) and is suitable for development, testing, production, or automation.
Looking for prebuilt images? Use Armbian Imager — the easiest way to download and flash Armbian to your SD card or USB drive. Available for Linux, macOS, and Windows.
