My name is Mohammad Abdelhadi, I am working on research using a USB wireless card (WUSB600N) which works by a driver from Ralink (rt3572). In order to achieve my task, I am trying to modify that driver. One of the ways, I tried to call a function written in different module from that which I am working in. Every thing went fine (make & make install) until the modprobe command when i got (Unknown Symbol) about that function. I tried many ways to solve that problem like; Export_Symbol, and function pointers but, with no results!
Therefore, could you please help me in order to solve the problem of Unknown Symbol?
Thank you in advance..
