Hi,
My hikey 960 works fine in Android 9 with kernel version 4.9 built by AOSP source code.
For newest kernel features, I tried to change the kernel version to 4.19 by flashing the latest factory image hikey960-linaro-2020.02.24-factory-d33c0c48.zip with the follwing steps:
- extract the factory zip file
- switch to root
- run flash-all.sh
After flash the factory image, the kernel can boot as normal, and the /data directory can be mounted successfully. But the /sdcard/ directory is created but cannot be accessed since the the link of /sdcard/(/sdcard/->/storage/self/primary->/mnt/user/0/primary) does not exist.
I don’t know whether the old version was built from AOSP, some configurations are not matched
Could you please help me fix the problem? Thanks a lot!!
