All:
First off, thanks to Brian Hensley and Robert Nelson for their wealth of
information and support.
I am a retiree that, after a 30+ year stint building electronic/mechanical
devices in the medical research field in a MS Windows centric university ,
thought that I would expand my horizons and decided to play with the BBxM.
I am running Ubuntu 12.04 and have gotten to the point where I am ready to
try and compile a u-boot.img in order to
set the pinmux values. I have downloaded and ran the TI Pinmux utility and
have made the mux.h and pinmux.h files. I have the u-boot source file from
denx.de and have expanded it and have found the board/ti/beagle and evm
subdirectories.
I have read a lot of stuff on the internet but since things change daily I
want to check on several things.
Bear with me if I am asking obvious questions but I am still learning to
get around in the linux environment and I have seen conflicting info in
various posts.
1. Where in the tree do these files go? Do I need to make changes to evm.h?
2. I have the spidev working that RCN made available via the uEnv.txt
change uncommenting buddy = spidev. Will my changes to the pinmux affect
this.
i.e Do I have to set the SPI3 and SPI 4 pins as well as the I2C pins in
the utility?
3. Should I assume that the baseline that is given by the pinmux utility
sets all of the proper pads for the correct functioning of the BBxM?
4. Am I going dangerously wrong in any of this??? Have I missed anything?
I bought 3 BBxMs off of eBay and gave one to my buddy that just retired as
Director of IT at the university where I worked. I had Ubuntu and lxde
already running on the BB.
I told him the first one is free - just like crack, and yes he is addicted.
Thanks in advance for your help
Jon
