may be the vermagic...if you do a 'modinfo kernelModule.ko' it will list what the vermagic is and it should match your kernel version on your phone, adb shell cat /proc/version
If the vermagic does not match, try setting the EXTRAVERSION in the /path/to/kernel/Makefile to match the kernel version and rebuild. This is an example of what to look for and set in the Makefile: VERSION=3 PATCHLEVEL=0 SUBLEVEL=15 EXTRAVERSION=-962322 - bridgette ________________________________ From: "arun1...@iiitd.ac.in" <arun1...@iiitd.ac.in> To: android-kernel@googlegroups.com Sent: Thursday, April 18, 2013 4:38 AM Subject: [android-kernel] Re: kernel modules "hello world " in samsung n8000 Hi, I am also facing exactly similar problem while Kernel Module Development with HTC Explorer Device.
