我换了2张卡都是不可以的。
主要问题就是出现在
1.删除所有的分区
2.烧uboot，sudo dd if=u-boot-sunxi-with-spl.bin of=/dev/sdb bs=1024 seek=8
3.创建分区fat16，ext4之后，分别把zimage以及dtb文件拷贝，以及root.tar解压到第二个分区。
4.插入tf卡运行，此时log根本没有。怀疑是分区的时候将uboot弄没了，重新烧uboot到tf卡，此时发现TF卡已经无法挂载到ubuntu主机上。
5.怀疑是dd命令出错？还是TF卡的问题，我用的TF卡一个是16G（闪迪），一个是64G（三星）都是同样的问题，而且uboot会提示
part_get_info_efi: *** ERROR: Invalid GPT ***
part_get_info_efi: *** Using Backup GPT ***
是我哪里操作有误吗？
已经解决了，就是因为分区的原因，之前分区的时候将GPT 搞坏了，重新全部分区之后解决的（diskgenius重新格式化）

第二个分区有问题, 或者卡坏, 或者文件系统代码没有编译进来.

是我哪里操作有误吗？
按照晕哥的步骤做了，我的主机是Ubuntu16.04，用的是USB 的读卡器，TF卡是sandisk，16G
1.将TF卡分全部删除
2.sudo dd if=u-boot-sunxi-with-spl.bin of=/dev/sdb bs=1024 seek=8
3.出现问题,GParted分区工具提示GPT 崩溃，继续流程
4.创建2个分区，一个32M，一个是剩下的全部，这个时候还是会提醒GPT崩溃，点击确定之后可以进行分区
5.将zimage和dtb文件拷贝到文件32M，另一个是将root.tar解压到15G的另一个分区。
以上步骤完成后，插入TF卡，没有任何的反应，怀疑是uboot没有烧进去。重复第2个步骤，然后出现找不到mmcblk2的log，VFS无法挂载
log如下：从下面的log看，
[ 1.405767] VFS: Cannot open root device "mmcblk0p2" or unknown-block(179,2): error -6
[ 1.413788] Please append a correct "root=" boot option; here are the available partitions:
[ 1.422164] b300 15159296 mmcblk0
这个分区是mmcblk0，而启动命令参数是root=/dev/mmcblk0p2,难道需要改启动参数。但是我使用的晕哥的这个固件(uboot,zimage,dtb,rootfs)
