Other Parts Discussed in Thread: AM3358
Hi:
Recently I need to compile the am3358 net driver(cpsw) as a modules(the defautl the cpsw compiled into kernel), so I select the cpsw to M. and I get the ti_cpsw.ko.
When I reboot the linux system, the ti_cpsw is not intalled(I have already do "make modules_install"). so I input the command "modprobe ti_cpsw" and I could found the cpsw module as using the lsmod command.
however, when I input the command "rmmod ti_cpsw" that I want to remove the cpsw module from kernel I get some error as below:
