I can't insert module on mini2440. I command 'insmod filename.ko' while I'm a root. There is a error message insmod: cannot insert 'filename.ko' : File exists I've checked in /dev and there's no a file that have the same name. How can I solve this problem? thank you Regards
insmod module
Hi I'm sorry. It's my mistake. I did't change "DEVICE_NAME" in the sourcecode. I thought the module's name in /dev will be the same with the soucrecode'name. so I can insert module now. Thank you everyone. Regards
