hi all 我们现在在用am3354来移植图形加速，遇到个问题，麻烦大神解疑。 使用的processor SDK版本是02.00.02.11 在根据我们自己的板子的硬件修改am335x-evm.dts和.config文件以后，4.1.18的内核可以正常启动并挂载UBI文件系统。 rootfs使用的是sdk里面的filesystem/arago-base-tisdk-image-am335x-evm.tar.gz这个解压出来的，并且从tisdk-rootfs-image-am335x-evm.tar.gz拷入了qt5的库，还有sgx相关的库，比如libEGL之类的库。 然后尝试跑一个ti的基于qml的使用opengl的图形加速例子程序，但是遇到错误： root@am335x-evm:/home/qml3358# ./qml3358 -platform eglfs PVR_K:(Error): BridgedDispatchKM: Driver initialisation not completed yet. PVR:(Error): PVRSRVBridgeCall: Failed to access device. Function ID:3223086849 (strerror returns no value.). [0, ] PVR:(Error): PVRSRVEnumerateDevices: BridgeCall failed [0, ] PVR:(Error): PVRSRVConnect: Unable to enumerate devices. [0, ] PVR:(Error): Couldn't connect to services [0, ] Could not initialize egl display Aborted 因为这个qml3358的例子程序，在ti开发板TMDSSK3358上是可以跑的。所以不是kernel问题就是rootfs问题。 不知问题在哪里？ 因为rootfs启动的时候，sgx的驱动部分加载，也没报什么错，所以不知所以。 这里也附上我启动的log，dts文件，还有.config文件。
