I am part of a group of people studying high performance network protocols. We have a transport layer protocol that makes use of a kernel module that we created. The problem we are having is that after compiling the module and trying insmod we get Error: Invalid module format. We know the module is fine because we have compiled it on x86 machines and on a Raspberry Pi and we have no problems loading it. My guess is that there is a mismatch between the kernel source which you have on your website and the actual kernel version on our Udoo Quad. Uname -r gives 3.0.35. The source you have on your website, I have no idea which specific version it is or if it matters. I downloaded the master branch After I downloaded the Kernel source, I put it in /lib/modules/3.0.35/build/ Inside that directory i ran the following: Code: make menuconfig make prepare make modules In menuconfig i enabled loadable module support. Everything went fine and it generated some files. After doing this, I can compile the kernel module without problems but I cannot load it. So far I have tested on Udubuntu and on Wheezy. I really don't know what is wrong and I am new to Linux kernel development. Any ideas on how to fix this?
Hi, still stuck. The problem is that I can compile the module but I cannot load it. Modinfo shows vermagic 3.0.35 ARMv5 This is in conflict with other modules from the OS that have vermagic 3.0.35 #7 Preempt ARMv7 So how come the module I am compiling with the kernel source provided by Udoo, end up with the wrong vermagic?
