Re: [Gumstix-users] buildroot version to use audio?

SourceForge Headquarters 225 Broadway Suite 1600 San Diego, CA 92101 +1 (858) 454-5900

Hi Martyn thanks for that, it seems to refer to verdex motherboards only?

I have a connex bt400.

I am still unable to get the audio working consistently. It has worked 
intermittently using buildroot 1513, I thought I had fixed it by 
reseating the audiostix2 board but now its gone again and doesn't seem 
to want to come back at all.

I'm now back on buildroot 1420 (so that bluetooth will work out of the 
box)(although it doesn't!), and the audiostix2 is once again saying
pxa2xx_ac97_reset: cold reset timeout (GSR=0x0) etc.
even though the light is still on etc.

Do you (or anyone else) think there is anything else that could be 
causing a problem software/ configuration wise or is my hardware faulty? 
The board is brand new but I guess its possible.

Thanks

Tim
