3. 开发板uboot配置文件位置

ubuntu@ubuntu1804:~/tina-d1-h/lichee/brandy-2.0/u-boot-2018/configs$ ls -lh
total 28K
-rw-rw-r-- 1 ubuntu ubuntu 5.1K May 25  2022 sun20iw1p1_defconfig
-rw-rw-r-- 1 ubuntu ubuntu 2.2K May 25  2022 sun20iw1p1_nor_defconfig
-rw-rw-r-- 1 ubuntu ubuntu 4.9K Mar 17 04:19 sun8iw20p1_defconfig
-rw-rw-r-- 1 ubuntu ubuntu 3.0K Mar 17 04:19 sun8iw20p1_nor_defconfig
-rw-rw-r-- 1 ubuntu ubuntu 2.4K Mar 17 04:19 sun8iw20p1_uart3_defconfig
ubuntu@ubuntu1804:~/tina-d1-h/lichee/brandy-2.0/u-boot-2018/configs$

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
