- From https://github.com/edk2-porting/edk2-rk3588/releases/tag/v0.9.1 - For example, for `rock-5b_UEFI_Release_v0.9.1.img` - `UEFI_EDK2_BOARD_ID` is `rock-5b` - **Important**: this has no effect unless optional extension is enabled - to test this out: - make sure to read carefully the instructions at https://github.com/edk2-porting/edk2-rk3588/blob/master/README.md - suppose you previously built the regular u-boot version with: - `./compile.sh BOARD=rock-5b BRANCH=legacy RELEASE=jammy` - now you can build the UEFI version with: - `./compile.sh BOARD=rock-5b BRANCH=legacy RELEASE=jammy EXT=uefi-edk2-rk3588` - write the produced image to SD or eMMC and boot it - use normally, or enter "UMS" mode by selecting that option in the grub menu - You can write image to eMMC, boot it, enter UMS, write it again to NVMe, reboot, press <ESC> in UEFI and boot from NVMe - Also works if .img is written to eg USB stick, and UEFI edk2 is separately deployed to SPI flash - **Important**: make _absolutely_ sure you are able to force Maskrom mode (by shorting pins, pressing buttons, etc) before writing an UEFI image to eMMC; UEFI has no RockUSB ("Loader mode" support) at all. The new "initramfs-usb-gadget-ums" extension hopes to address this, but it is not guaranteed to work.
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
- Example:
- 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
- Default:
- 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_DESKTOPis set toyes
- Default:
not set
- Values:
- 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
- Values:
- 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
- Values:
- 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
- Examples:

- MODULES_EDGE ( space-separated list of kernel modules ): appends modules to the kernel command line for edge kernel
- MODULES_BLACKLIST ( space-separated list of kernel modules ): appends modules to the kernel's blacklist/deny list for all kernel branches
- 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:

- Values:
- KERNEL_TEST_TARGET ( comma-separated list of kernel releases or branches ): if test targets are different for testings (internal switch)
