Internal build options

These options are used to declare variables used by the armbian build system to build a board-specific configuration.

If you are unsure about the documentation then invoke $ grep -r -A5 -B5 "BUILD_OPTION_HERE" /path/to/local/armbian/build/repository to get context to the option from the source code.

• BOARD_NAME ( company product version ): defines the board name used in welcome text, hostname and others relevant usage.The general convention is COMPANY PRODUCT VERSION - Often used as part of the scripting logic (namely for hacks) so follow the name declared in the board configuration.
  • Example: OLIMEX Teres A64
• BOARDFAMILY ( board-family ): defines the family of the board to apply board-specific configuration during build time such as adjustments for the temperature, LED behavior, etc..
  • Refer to sources table
  • Example: sun50iw1
• BOARD_MAINTAINER ( space-separated list of Github login ): Declares the maintainer of the board
• BOOTCONFIG ( u-boot identifier ): declares the name of the u-boot configuration for the build without the '_defconifig' suffix
  • Refer to the u-boot source tree to find configuration for the board
  • Example: teres-i
• BOOTSIZE ( int ): Declares the size of the boot partitin in Mib
  • Default: 256
  • Example: 256
• BOOT_LOGO ( string ): defines whether to use a eyecandy during bootloader phase
  • Values:
    • yes: Show the armbian boot logo
    • desktop: Show the armbian boot logo when BUILD_DESKTOP is set to yes
  • Default: not set
• CRUSTCONFIG ( crust identifier ): declares the name of the crust defconfig configuration for the build. Specify only if the board has Allwinner CPU with AR100 coprocessor and SOC is supported by crust firmware.
  • Refer to the crust source tree to find configuration for the board
  • Example: nanopi_m1_defconfig
• IMAGE_PARTITION_TABLE ( string ): defines which disklabel type to use
  • Values:
    • msdos: Use dos/msdos disklabel
    • gpt: Use GPT disklabel
  • Default: msdos
• BOOTFS_TYPE ( filesystem ): defines the expected filesystem for the boot file system
  • Values:
    • none: Uses /boot on the root filesystem
    • ext4: Use the Fourth Extended Filesystem
    • ext2: Use the Second Extended Filesystem
    • fat: Use the File Allocation Table 32
  • Default: ext4
• DEFAULT_OVERLAYS ( space-separated list list of dtb overlays ): defines dtb overlays that are enabled by default. There is a basic dtb for each family but they have different level of used SoC features. Board X might have four USB ports but others might not. Therefore other does not need to have those enabled while board X does.
  • Examples:
    • usbhost0
    • usbhost2
    • usbhost3
    • cir
    • analog-codec
    • gpio-regulator-1.3v
    • uart1

• MODULES_BLACKLIST_LEGACY ( space-separated list of kernel modules ): appends modules to the kernel's blacklist/deny list for legacy kernel
• MODULES_BLACKLIST_CURRENT ( space-separated list of kernel modules ): appends modules to the kernel's blacklist/deny list for current kernel
• MODULES_BLACKLIST_EDGE ( space-separated list of kernel modules ): appends modules to the kernel's blacklist/deny list for edge kernel
• SERIALCON ( comma-separated list of terminal interfaces [:bandwidth] ): declares which serial console should be used on the system
  • Example: ttyS0:15000000,ttyGS1
• SKIP_ARMBIAN_REPO ( boolean ): Whether to include the armbian repository in the built image
  • Values:
    • yes: Include (default)
    • no: Do NO include

  • Values:
    • yes: Enable video-related configuration
    • no: Disable video-related configuration
• KERNEL_TARGET ( comma-separated list of kernel releases or branches ): declares which kernels should be used for the build
  • Values:
    • legacy: Use legacy kernel
    • current: Use current kernel
    • edge: Use edge kernel
    • [branch]: Use specified [branch] kernel
    • [none]: Exits with error
• KERNEL_TEST_TARGET ( comma-separated list of kernel releases or branches ): if test targets are different for testings. Also applies to build list generation. (internal switch)
• KERNEL_UPGRADE_FREEZE ( comma-separated list of kernels with versions obove which they stop updating, example: KERNEL_UPGRADE_FREEZE="vendor-rk35xx@24.8.1,current-rockchip-rk3588@24.8.2" )
