按照论坛里的教程：
1) 删除TF卡所有分区
2) 将uboot写入到sd卡8k偏移处(必须8K偏移, brom龟腚的)。
sudo dd if=u-boot-sunxi-with-spl.bin of=/dev/sdX bs=1024 seek=8
3) 建立第一个分区,大小32M(可以随意填写), 格式FAT16, 把zImage, sun8i-v3s-licheepi-zero-dock.dtb拷贝到 这个分区
4) 建立第二个分区，用尽剩余空间,格式ext4, 把buildroot产生的rootfs.tar解压到该分区根目录
tar xvf output/images/rootfs.tar -C /挂载的tf卡第二个分区目录
在V3S ZERO开发板上运行后，出现如下情况：

板子启动不了？是什么情况？
如果把第二步改一下：
4) 建立第二个分区，大小100M,格式ext4, 把buildroot产生的rootfs.tar解压到该分区根目录
tar xvf output/images/rootfs.tar -C /挂载的tf卡第二个分区目录
第二个分区改成100M，就可以正常启动。200M就不行了，是什么问题呢？

按照这个论坛做的，目前不知道该如何解决问题
离线
第二个分区100M可以，大于100M就不行了
离线
论坛里说sudo解压缩rootfs，明天我试试

烧到tf卡里后，卡住了
