关于DVRRDK4.1交叉编译工具问题



DVRRDK 4.1中文档《DM81xx_DVR_RDK_Install_Guide》提到使用Arm 2009q1-203 Tool chain也就是arm-none-linux-gnueabi-,相关TI wiki上也是arm-none-linux-gnueabi-,但DVRRDK 4.1安装好之后rules.make中默认都是配成arm-arago-linux-gnueabi-,且在ti_tools\cgt_a8\arago\linux-devkit\arm-arago-linux-gnueabi目录下提供了该编译工具。究竟是用arm-arago-linux-gnueabi-,还是安装Arm 2009q1-203使用arm-none-linux-gnueabi-?二者有何区别呢?
