am335x gfxsdk GPU

下载了 http://software-dl.ti.com/dsps/dsps_public_sw/sdo_sb/targetcontent/gfxsdk/latest/index_FDS.html 网站的 Graphics_SDK_setuplinux_hardfp_5_01_01_02.bin SDK包，并编译过了，下载到板子上后出现了如下问题：

请大侠们指导指导！这里先拜谢了！

Jian Zhou：

首先确认下你的板子是AM3354的芯片么？

xie terry：

回复 Jian Zhou:

hello，板子用的是3358的芯片

Jian Zhou：

回复 xie terry:

看了下，你的gfxsdk用的比较新，确认下板子上跑的Linux SDK的是不是最新版本

xie terry：

回复 Jian Zhou:

用的是 3.2 的linux内核

Jian Zhou：

回复 xie terry:

3.2的kernel是比较老的版本了，最新的SDK是4.4的内核，我怀疑是gfxsdk的版本和Linux SDK的版本不匹配。

xie terry：

回复 Jian Zhou:

TI官网上只有 Graphics_SDK_setuplinux_hardfp_5_01_01_02.bin SDK包可下载，有没有支持3.2内核的 GPU包？？

或是3.2 的内核中做什么调整让其可用？？

Jian Zhou：

回复 xie terry:

最新的3.2内核的kernel是SDK06，你可以去下面地址下载完整的SDK包：

http://software-dl.ti.com/sitara_linux/esd/AM335xSDK/06_00_00_00/index_FDS.html

里面带有对应的GDK的安装包。

Yaoming Qin：

建议您升级到最新的sdk，另外可以参考 https://community.imgtec.com/developers/powervr/graphics-sdk/ 编译sgx demo

回复 Jian Zhou:

你好，下载了这个链接的资源后，基本正常了，但遇到了如下问题：

/opt/gfxsdkdemos # ogles2/OGLES2MagicLantern Can't open keypad input device (/dev/input/event0)Can't open remote control input device (/dev/ttyS1)Display stride is not a multiple of 32 pixels – accumulation will go wrongPVRShell: EGL 1.4 initialized

请问怎么解决？？
