Build LS1028A BSP composite firmware and boot partition
LS1028A BSP composite firmware consists of atf bl2, atf bl3 fip frimware, bootloader environment, secure headers, Ethernet
MAC/PHY firmware, dtb, kernel and tiny ramdisk rfs, etc. This composite firmware can be programmed at offset 0x0 in flash device
or at offset block# 8 in SD/eMMC card.
To generate LS1028A BSP composite firmware for Layerscape platform, directly run the following command:
Usage:
$ flex-builder -i mkfw -m <machine> -b <boottype> [-B <bootloader>] [-s]
Examples:
$ flex-builder -i mkfw -m ls1028ardb -b xspi
firmware_ls1028ardb_uboot_xspiboot.img will be generated.
$ flex-builder -i mkfw -m ls1028ardb -b xspi -s
firmware_ls1028ardb_uboot_xspiboot_secure.img will be generated.
$ flex-builder -i mkfw -m ls1028ardb -b sd
firmware_ls1028ardb_uboot_sdboot.img will be generated.
$ flex-builder -i mkfw -m ls1028ardb -b sd -s
firmware_ls1028ardb_uboot_sdboot_secure.img will be generated.
Similarly, the following composite firmware can be generated with the same usage of flex-builder command:
firmware_ls1028aqds_uboot_sdboot.img
firmware_ls1028aqds_uboot_sdboot_secure.img
firmware_ls1028aqds_uboot_xspiboot.img
firmware_ls1028aqds_uboot_xspiboot_secure.img
firmware_ls1028ardb_uboot_emmcboot.img
To generate LS1028A BSP boot partition tarball, run the command as below:
$ flex-builder -i mkbootpartition -a arm64
or
$ flex-builder -i mkbootpartition -a arm64 -s (for secure boot)
The command above will generate all needed images including kernel image, dtb, distro boot script, flex_linux_<arch>.itb, small
ramdiskrfs, etc. Flex-builder automatically builds the dependent images if they are not present.
How to build application components in Flexbuild
The following commands are some examples of building application components.
Usage:
$ flex-builder -c <component> -a <arch> # build single application component for specified <arch>
Example:
$ flex-builder -c apps # build all apps components for arm64 arch
$ flex-builder -c tsntool # build tsntool component for arm64 arch
$ flex-builder -c wayland # build wayland component for arm64 arch
$ flex-builder -c weston # build weston component for arm64 arch
$ flex-builder -c cst # build cst component, needed for secure boot
(arm64 is the default arch if -a <arch> is not specified)
To add new application component in Flexbuild, follow the steps below:
1. Add new <component> to apps_repo_list and set CONFIG_BUILD_<component>=y in configs/build_xx.cfg.
