Beaglebone Black angstrom

Status Update:
This is a list of working Not working items, so you do not get disappointed after reading the post.  This is  a work in progress...

Angstrom:
GPIO
ADC
I2C1
SPI almost, having some issues with CLK, and Data input output.

ArchLinux:
:-(



First Using angstrom distribution:
opkg is the app-get for angstrom....

Linux beaglebone 3.8.11 #1 SMP Wed May 8 07:34:27 CEST 2013 armv7l GNU/Linux

after opkg update, opkg upgrade

Linux beaglebone 3.8.13 #1 SMP Thu Sep 5 16:35:35 CEST 2013 armv7l GNU/Linux

Install Sudo
opkg install sudo

Network settings:
This post here is great source for setting Static IP
http://derekmolloy.ie/set-ip-address-to-be-static-on-the-beaglebone-black/

add user:
su
useradd xyz-user
passwd xyz-user

Update Time and Time Zone:
rm /etc/localtime
ln  /usr/share/zoneinfo/EST /etc/localtime

/usr/bin/ntpdate-sync 

nano default/ntpdate     to set / enable sync server

date             to check your new time

http://support.ntp.org/bin/view/Servers/NTPPoolServers

north-america.pool.ntp.org

Using GPIO:
#echo 44 > /sys/class/gpio/export

Using the I2C:
i2cdetect -y -r 1
root@beaglebone:~# i2cdetect -y -r 1
     0  1  2  3  4  5  6  7  8  9  a  b  c  d  e  f
00:          -- -- -- -- -- -- -- -- -- -- -- -- -- 
10: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 
20: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 
30: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 
40: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 
50: -- -- -- -- UU UU UU UU -- -- -- -- -- -- -- -- 
60: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 
70: -- -- -- -- -- -- -- --   

i2cdump -y 1 0x50 w     or
i2cdump -y 1 0x50 b

Using the SPI:
I found the required files in /lib/firmware/ BB-SPIDEV*
all I did finally, is echo this line

root@beaglebone:/lib/firmware# echo BB-SPIDEV0 >  /sys/devices/bone_capemgr.9/slots

Then ls /dev/spi* and here is what I got...

Now what is next? the question is what is really here that works?



Using Analog Inputs:

sh-4.2# echo cape-bone-iio > /sys/devices/bone_capemgr.*/slots

sh-4.2# find /sys/ -name '*AIN*'

/sys/devices/ocp.2/helper.14/AIN0

/sys/devices/ocp.2/helper.14/AIN1

/sys/devices/ocp.2/helper.14/AIN2

/sys/devices/ocp.2/helper.14/AIN3

/sys/devices/ocp.2/helper.14/AIN4

/sys/devices/ocp.2/helper.14/AIN5

/sys/devices/ocp.2/helper.14/AIN6

/sys/devices/ocp.2/helper.14/AIN7

sh-4.2# cat /sys/devices/ocp.2/helper.14/AIN1

OR  

sh-4.2# cat /sys/devices/ocp.2/helper.14/AIN*

BeagleBone Black Updating the Software
Getting Started with BeagleBone Black
============================================================
Now, I am trying arch Linux to see if it works better:

http://archlinuxarm.org/platforms/armv7/ti/beaglebone-black


Steps I used:

1. pacman -Syu
2. passwd
3. pacman -S sudo adduser gcc make
4. adduser username
5. EDITOR=nano visudo
6. copy my files
7. 
   

To Setup eth0 configuration Static:
systemctl disable netctl-ifplugd@eth0
cp /etc/netctl/examples/ethernet-static /etc/netctl/ethernet-static
nano /etc/netctl/ethernet-static #edit to you liking
Use /24 for  255.255.255.0
Use /16 for 255.255.0.0
netctl enable ethernet-static
reboot.
