Hi guys, yesterday I opened my freerunner to check whether mine FR is affected by R3004 issue [1].
It was, I put a piece of wire there instead of those two caps and volume got better! I have also connected sine wave from generator to the WD8753 mic input and cheched it on the WD8753's output with the oscilloscope. It seemes that the audio codec chip gets into trouble (distortion, oscillations) if the overall audio path has higher gain than 1. I'm going to write more about this soon, with the scope pictures included (taken by my camera, I don't have DSO at home :-/ ) But ... when I was dismounting the phone, I dammaged the bluetooth module. The module itself may be OK, but the flex cable is torn off. Don't you have any idea where can I buy some spare? Thanks, Zbynek [1]http://lists.openmoko.org/pipermail/community/2009-August/052914.html _______________________________________________ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
