可以從官網下載
busybox-1.35.0
增加變量路徑
#source /opt/fsl-imx-wayland/5.4-zeus/environment-setup-aarch64-poky-linux
直接make 發現錯誤如下：
root@huang-VirtualBox:/home/busybox-1.35.0# make

解決辦法：
make menuconfig進入菜單
->>Settings --->Cross Compiler prefix（回車），填入aarch64-poky-linux-
->>Settings --->Path to sysroot（回車），填入/opt/fsl-imx-wayland/5.4-zeus/sysroots/aarch64-poky-linux
再執行：
#make&&make install后，會生成_install文件夾，其中包含link到busybox的所有工具，替換到rootfs中即可
# cd /install
# tar -cjvf busybox.tar.bz2 *
將打包后的 busybox.tar.bz2 壓縮包通過U盤、FTP或者NFS等方式拷貝到目標板，並分別解壓到/bin和/sbin目錄。
將壓縮包的bin目錄解壓到根目錄/
# cd busybox.tar.bz2 ~/ # cd # tar -jxvf busybox.tar.bz2 bin -C /
將壓縮包的sbin目錄解壓到根目錄/
# tar -jxvf busybox.tar.bz2 sbin -C /
驗證：
#busybox
