TI中文支持网linux内核使用ti-processor-sdk-linux-rt-am335x-evm-03.01.00.06，
Graphics SDK使用
Graphics_SDK_5_01_01_02
操作按照http://processors.wiki.ti.com/index.php/Graphics_SDK_Quick_installation_and_user_guide这里的说明，
在执行/etc/init.d/335x-demo的时候出现错误：

请问这是怎么回事呢？
我看了下v7_dma_map_area函数是cache-v7.S文件里面，system.map中已经编译进去了。
Jian Zhou：
这个graphic SDK是比较老的版本，应该是和最新的processor SDK不匹配。

我在官方上没找到更新的graphic SDK了。那这一版本的processor SDK要匹配哪版的graphic SDK？

回复 willie xu:
最新的processer SDK 的Graphic的架构和以前也不一样了，请参考：
