这款开拓板的配置也是相称高，4核 A53 ,主频1.6G, 内存2G, 一个有7个网口，2个RGMII接口 ，4个QSGMIIR接口 ，还有一个10G口，芯片上共有3个USB3.0口，可以用于支持5G上网模块，，自带的LSDK 支持arm64 ubuntu文件系统，性能秒杀树莓派及BBB。且在openwrt上也已支持LS1043A，可以用来做家庭网关。唯一的不敷之处便是短缺了显示接口。
基于flexbuild_lsdk1909_update_221019
按如下步骤编译出SD勾引镜像，并烧录至SD卡,过程当中有可能会编译失落败，可以翻墙：
1 sd atf:
flex-builder -c atf -m ls1043ardb -b sd
2 sd mkfw
flex-builder -i mkfw -m ls1043ardb -b sd
3 sd linux compie
flex-builder -c linux -m ls1043ardb -b sd
4 sd mkbootpartition
flex-builder -i mkbootpartition -m ls1043ardb -b sd
5 sd apps compile
flex-builder -c apps -a arm64 -m ls1043ardb -b sd
6 sd mkrfs compile
flex-builder -i mkrfs -r ubuntu:main -m ls1043ardb -b sd -a arm64
7 sd merge-component
flex-builder -i merge-component -a arm64 -m ls1043ardb -b sd
8 sd packrfs
flex-builder -i packrfs -a arm64 -m ls1043ardb -b sd
9 sd burn
flex-installer -b build/images/bootpartition_LS_arm64_lts_4.19_201911291016.tgz -r build/images/rootfs_lsdk1909_LS_arm64_main.tgz -f build/images/firmware_ls1043ardb_uboot_sdboot.img -d /dev/sdc
开拓板上面的SW4 SW5拨码开关记得拨对，电源线及串口线接好，如下所示：
