4. Tina系统指定配置文件
ubuntu@ubuntu1804:~/tina-d1-h/device/config/chips/t113/configs/100ask$ cat BoardConfig.mk
LICHEE_CHIP:=sun8iw20p1
LICHEE_ARCH:=arm
LICHEE_BRANDY_VER:=2.0
LICHEE_BRANDY_DEFCONF:=sun8iw20p1_uart3_defconfig
LICHEE_KERN_VER:=5.4
LICHEE_KERN_DEFCONF:=sun8iw20p1smp_defconfig
LICHEE_REDUNDANT_ENV_SIZE:=0x20000
5. 编译打包与更新
ubuntu@ubuntu1804:~/tina-d1-h$ mboot
t113_100ask t113 t113-100ask
build_boot platform:sun8iw20p1_uart3 o_option:uboot
