各位大神:
我也遇到编译extra相关的驱动模块的问题:
1.在Linux Processor-SDK包安装目录里执行sudo gedit Makefile 执行出现以下的故障:
root@baoyangyang-virtual-machine:/home/baoyangyang/ti-processor-sdk-linux-am57xx-evm-06.00.00.07#  make cmem-mod
================================
Building CMEM Module
================================
/bin/sh: 51: export: --sysroot: bad variable name
make: *** [cmem-mod] Error 2

1.在进入到/board-support/extra-drivers目录里执行sudo gedit Makefile 执行出现以下的故障:
root@baoyangyang-virtual-machine:/home/baoyangyang/ti-processor-sdk-linux-am57xx-evm-06.00.00.07/board-support/extra-drivers# sudo make cmem-mod
make: *** No rule to make target `cmem-mod'.  Stop.
