"Invalid module format" for compiled modules

joe1203 · Published in 2016-1-20 21:07:39

Hi Expert, please advise if I did anything wrong when compiling modules

Install Ubuntu 12.04 in virtualbox, clone the source of linux-3.4-sunxi from github, did some code editing and compile the modules with arm-linux-gnueabi-* . But when playing around on Fedora 22, I cannot load the module and receive "Invalid module format" error. Here is the output of modinfo, file and readelf -h, any clues?
