Re: [Openbts-discuss] install openbts on beagle

[David A. B. <dbu...@jc...>]

Anne, Ken -

Harvind and I have been working on a port to the Gumstix Overo Earth,  
with assistance from Philip Balister, who is cc'd on this e-mail.  We  
believe that it is possible to build a limited-capacity system based  
on this board, supporting 4 active timeslots instead of 8.

The CPU and build process for the Overo are very similar to those for  
the Beagle, maybe identical.  On the server, there is a tarball  
called r2.3JeanLafitteOE intended for use with Open Embedded, but  
that does not include the recipe files.  My current ones are attached.

1. I put these files in org.openembedded.dev/recipes/openbts
2. I put openbts-2.3JeanLafitteOE.tar.gz in org.openembedded.dev/ 
recipes/openbts/sources
3. I add openbts to the package list in org.openembedded.dev/recipes/ 
images/omap3-console-image.bb
4. I bitbake omap3-console-image

I got this far with Philip's help, but there's still a problem  
because not all of the required configuration files are getting into  
the image.  I'm sure the problem and the fix will be the same for  
both the Overo and the Beagle.

Philip - Would you mind sending us all copies of the latest recipe  
files and/or commenting on the correctness of all of this?

The biggest block to going to low-end OMAP boards, though, is the  
problem we are having getting the USRP to work with a 26 MHz clock.   
We need to do that to get rid of the polyphase resamplers in the  
current transceiver.  That will give us a significant savings in  
computation, without which we cannot run on these small systems.  We  
are working on that problem with GNU Radio and others.
