Your address is in I/O address space, not memory address space. Take a
look at io_rw.c in iotools, you need to be using inb/outb (not just
reading/writing memory).

Hey guys, me again. :)
So, my device is working great now that I can access the GPIO pins via
userspace (using iotools w/ Tom Sylla's help) and can power on the
device. However, I'd like to be able to toggle the power on via a kernel
driver as well, but I'm having trouble accessing the same memory
Hey guys, me again. :)
So, my device is working great now that I can access the GPIO pins via
userspace (using iotools w/ Tom Sylla's help) and can power on the
device. However, I'd like to be able to toggle the power on via a kernel
driver as well, but I'm having trouble accessing the same memory
