Hello,
I just got a TWR-MPC8309 from Freescale running Embedded Linux OS. The kernel
version is Linux 2.6.11+pq3 patches and the kernel preconfig file is
linux_2.6.11_mpc8548_cds_def.config.
That's a really OLD kernel, plus it doesn't seem to match your hardware.
MPC8309 is a very different beast from the MPC8548.
I'm new to processors running Linux and I'm having a hard time trying to
understand how can I program the GPIO and use them. Is there a tutorial or any
documentation you could provide me to get started on accessing the processor
pins please?
I'm using CodeWarrior Development Studio for Power Architecture version 10.0.2
and I haven't found a library that includes the functions to access the pins
functionality. Is there any documentation you could suggest me to do that
please?
Try looking at the Linux kernel source file 'Documentation/gpio.txt'
