是这样操作的吗。

是的，ssbl之前的部分， 根据log已经烧写了，到ssbl这一步失败的。最开始怀疑是自己编出的image问题，最后直接下载 百度网盘里面的buildroot整个文件，还是出错

4

你选择的是只烧写rootfs 的配置文件，是需要烧写这个吗。我这里试试看烧写这个。

5

您好，请问您那边是正常的吗？ 按理说往emmc里面download数据，按照这个设定的offset，应该就OK了。也试过其它方式烧写，也是到这个位置ssbl失败。

log中有段设备重连， 是不是表示烧录数据emmc位置不对，开发板emmc硬件reset，然后才有这个重连的log？

6

我这导入配置文件按默认的烧写是正常的。

7

用rootfs.tsv 这个还是不行；好在 systemall.tsv这个配置文件能用。谢了
