1.修改bootloader 编译：添加 --fastboot-write
cd bootloader/uboot-repo
./mk s7d_bm201 --vab --avb2 --fastboot-write
#./mk s7_bh201 --avb2 --vab --fastboot-write
echo "compiled bootloader success!!!"
cp build/u-boot.bin.signed ../../device/amlogic/ross/bootloader.img
cp build/u-boot.bin.sd.bin.signed ../../device/amlogic/ross/upgrade/
cp build/u-boot.bin.usb.signed ../../device/amlogic/ross/upgrade/
echo "copy uboot file success!!!"
cd ../..-
进入bootloader 模式下:
setenv otg_device 0;saveenv;reset
3.输入以下命令
adb reboot bootloader
fastboot flashing unlock
fastboot reboot
adb root
adb disable-verity
adb reboot
