./build.sh firefly-rk3399-buildroot.mk
./build.sh
编译uboot、内核都对的，但是编译rootfs报错
总是说Found old config, override it? (y/n):
此时不论输入y还是n，都报错。比如输入n
Found old config, override it? (y/n):n
Command exited with non-zero status 1
you take 0:03.89 to build builroot
ERROR: Running build_buildroot failed!
ERROR: exit code 1 from line 1315:
/usr/bin/time -f "you take %E to build builroot" $COMMON_DIR/mk-buildroot.sh $RK_CFG_BUILDROOT $DST_DIR
即使删除SDK，重新解压缩、更新，再直接编译buildroot固件也不行
把envsetup.sh中的下面这段屏蔽，貌似就可以编译成功
# if ! diff ${CONFIG}{,.new}; then
# read -t 10 -p "Found old config, override it? (y/n):" YES
# [ "$YES" != "n" ] && cp ${CONFIG}{.new,}
# fi
