Greetings,
I just discovered this list while beating my head against the wall
(kernel noobs do that a lot, I hear). I thought I'd introduce myself.
I'm mainly an EE but with fairly extensive Unix and Linux user space
coding and with embedded system programming. I'm a newborn infant when
it comes to the kernel.
I'm working with the BeagleBone and Robert Nelson's Angstrom derivative
https://github.com/RobertCNelson/stable-kernel
I intend to embed the BB in our new product if I can solve a small
problem. The BB has 2 SPI ports, 1 with 1 chip select and the other
with 2. Only one port is supported in the standard kernel. I found
some info that guided me into activating the new port and having all
three devices enumerated in /dev.
What I have not yet been able to do is figure out how to enable that
second chip select line. So my first question is, where do I start
looking for the existing code? I'm hoping that I'll be lucky enough to
reuse that code, changing a bit or two in the CPU register.
Thanks,
John
