按照编译指导编译出来的img，卡在开机logo处，不能启动
如题：主机16.04，按照http://wiki.t-firefly.com/zh_CN/AIO-3288J/linux_compile.html的编译步骤，编译的AIO-3288J-Buildroot 固件，烧入后，卡在开机logo处，开机的log见附件session.log.

楼主可以查看一下 CPU 上的芯片信息，应该是类似 SAAKT23028W，带 ‘W’ 后缀。
启动脚本 /etc/init.d/S10libmali 会根据 GPU 链接对应库文件，但命令 `ln -s libmali-midgard-t76x-r14p0-r1p0-wayland.so libmali.so` 缺少 -f 参数导致链接没更新，而使用了默认链接，加上 -f 参数即可 `ln -sf libmali-midgard-t76x-r14p0-r1p0-wayland.so libmali.so`。
