MQ-Pro overlay挂载的问题
-
sdk: tina v2.0
patch: https://github.com/mangopi-sbc/Tina_d1x_append问题：挂载
/dev/by-name/rootfs_data找不到块设备查了相关资料，需要修改
sys_partition.fex,看了
tina-d1-h/device/config/chips/d1-h/configs/mq_pro/sys_partition.fex文件，没看到有UDISK这个分区。
-
UDISK分区可能是pack打包程序生成，也可能是烧录软件生成的，也可能是运行的时候脚本生成的，我还不确定。

原因：
打上patch https://github.com/mangopi-sbc/Tina_d1x_append， lunch选择mq pro的板卡进行编译，tina/target/allwinner/<方案名>/base-files/etc/config/fstab这个文件并没有正常，导致无法成功将UDISK分区挂载到/overlay -
@lbuque 大哥，这个pack要怎么打，不会啊，全部下载放到SDK根目录下吗

大佬，我用的是D1H,和您这个是一个问题吗？
