TI中文支持网大家好：
我现在在用AM3354，想要使用SGX530来进行图形加速。
然后下载了Graphics_SDK_setuplinux_hardfp_5_01_01_02.bin
安装完毕
改了Rules.make，目前交叉编译器是arm-none-linux-gnueabi-的4.4.6编译器
然后
make BUILD=release OMAPES=8.x all_km
make BUILD=release OMAPES=8.x install_km
安装到了目标rootfs里面，也没问题。
执行
cd /etc/init.d/335x-demo的时候，遇到个错误，如下：
./rc.pvr: line 110: /usr/local/bin/pvrsrvctl: not found
不知哪位大神知道这是怎么回事？
我看网上有人说是因为编译pvrsrvctl的编译器，和我自己使用的编译器版本不一致造成的。因为pvrsrvctl是事先编译好的，不知是不是这个问题？
或者还有没有什么别的解决办法？
完整的log如下：

更新下进展
我用的是3.2.0的kernel
我把编译器从code sourcery的换成gcc-linaro-arm-linux-gnueabihf-4.7-2013.03-20130313_linux
这个错误没有了
但是也没能成功加载驱动。执行335x-demo的结果如下：

问题解决了么？咨询下，确定 pvrsrvctl 这个是事先编译好? 还是自己源码编译的时候产生的啊。想对 pvrsrvctl 分析分析。

没有解决
我们现在不是用graphic_sdk独立安装了
直接使用processor sdk了
02或者03版本都可以直接支持图形加速

你有没有，用起GPU后，跑QT的QML例子，就是会自动调用GPU渲染
然后工作12小时以上？
老的SDK版本，，发现工作几个小时活，会花屏。。。因为DRM驱动的BUG
Steven Liu1：
回复 xiyuan ma:
估计你说的是老版本的GPU代码会出现sync lost的问题，在花屏的时候是不是有sync lost的相关信息提示？这个网上是已经有个patch把问题解决了。
