Martyn,


thanks - this looks promising but I think there is an added complication - I 
am running 2.6.29 on the board and I think the comedi drivers were moved to  
kernel staging after this time.

opkg list |grep "kernel -"
kernel - 2.6.29-r46.1 - Linux kernel for OMAP processors

To be honest I think I am out of my depth on this and very short of time- I 
have had the BB running a stock system for a long while and haven't touched 
this, the git / bitbake system I setup yesterday on my linux box doesn't seem 
to match it and I haven't a clue what I am doing with it.

I think I'm going to try the ubuntu bb install, I understand debian etc a bit 
better and I think comedi is ready packaged for unbuntu...

Thanks for your help,

SA
