I am writing a driver/user space set of programs. The driver worked until yesterday and I don't understand why. I can open the driver but the first ioctl call to the driver hammers the computer. It is as if the call is going to the wrong address. Is there a way that I can get a load map giving me the address of the ioctl function and then perhaps I can compare that to the address that is being called from the user space program. I am trying to get a serial console working, but have too many males and not enough female connections...anyway that's another story. Any info that you could provide would be very helpful.
