Other Parts Discussed in Thread: TMS320C6748, OMAPL138
Hello everybody,
I've got the TMS320C6748 DSP Development Kit (LCDK) and want to do some audio signal processing.
To get this Board running I'm using the example 'mcaspPlayBk.c' (..\C6748_StarterWare_1_20_03_03\examples\lcdkC6748\mcasp).
I have no problems to load this program into the DSP. Via my smartphone I have pluged in some music to test the playback functionality. My problem is that I only can hear the music through the connected speakers when I'm pressing and hold the input jack relatively hard. Moreover there is a constant noise floor and the music only comes at best through the left side.
I have tried many different cables to exclude a defect cable/plug, but the problem still exists. Therefore my first guess is a mechanical defect of the input jack.
Is there something that I miss?
Kind regards,
Patrick
