QFIL烧写Flatbuild的固件失败, 这个问题如何排查？

[weixin_38498942]

1, 首先是对设备进行完全断电(断开电源和type-C). 重新烧写确认不是设备长时间处于9008 导致的.
2, 查看QFIL的烧机的log, 如果你看到以下的log:

从这个log中可以看出: ' Command packet length 1702240364 too large to fit'
是对应的固件中的对应镜像过大了, 设备分区表规定的大小, 所以就会导致qfil的烧机失败.

解决方法为:
我们在build镜像的时候, 会指定分区镜像的大小, 将其修改为小于分区表规定分区的大小的size, 从而我们打出来的镜像包可以使用qifl重新烧写这个固件.
