StreamBox on a BeagleBoard

Alejo Duque

A parallel track to the streambox on the alix board to be found here:

StreamBox Alix v.0.1

First Boot!

notes on the process:

Dad to buy a null modem cable and a hdmi video cable (but still need a monitor able to do hdmi).

Followed this partition scheme guideline:

Got the narcissus image build for angstrom, failed to boot!

** Unable to use mmc 0:1 for fatload **
Wrong Image Format for bootm command
ERROR: can't get kernel image!

Had rename and copy:

1. mv /media/boot/uImage /media/boot/uImage_
2. cp /media/root/boot/uImage-2.6.29-omap1 /media/boot/uImage

Then, boot like this:

1. mmcinit
2. boot

And, to log in just use root, theres no need for a password.

Second boot

I had to short pins 5 and 6 of the OTG usb port so to be able to make it behave as a host, this took me a while to figure out since no one on the IRC was helpful enough to even suggest more reading. The solution is somewhow buried inside the pages and is a problem or a bug that hit only revision B, so this means we have a board that is really part of development.

Anyways, I got the good luck to be able to solder a little dot between those pins, cut apart 2 USB cables to patch a new one with 2 mini-USB heads so to be able to connect the BeagleBoard with the USB Hub. Apart from this I had to buy an adaptor to feed the Board since the other one i had feeds the USB Hub.

Is cable paradise, seems that all the promised portability of the beagleboard got entangled so far.

here some code snippets:

Listing the connected devices to the usb hub:

root@beagleboard:~# lsusb 
Bus 001 Device 001: ID 1d6b:0002  
Bus 002 Device 001: ID 1d6b:0002  
Bus 002 Device 002: ID 05e3:0608 Genesys Logic, Inc. USB-2.0 4-Port HUB
Bus 002 Device 003: ID 05ac:1402 Apple Computer, Inc. 
Bus 002 Device 004: ID 1005:b113 Apacer Technology, Inc. Handy Steno 2.0 (256MB)

There you can see the USB to ethernet adaptor I had to buy so to allow some network connectivity to the board. You can see also a usb memory drive that got mounted automatically by the system.

So, finally i was able to ping and log in via ssh via ethernet (before i was logging in via jtag, direct via serial)

Now i will try to configure the beagleboard to export X..
