Hi , I am new to Linux world and need to complete a decoder class of V4L driver in short time. I can not find step by step information regarding how to debug a modular driver under Linux. Can anyone help to let me know how to debug a device driver in Linux environment such as V4L driver. Best Regards, Olive ----- Original Message ----- From: "Troy L.
