Hi all, i have been working on the am3703 with beagleboard default kernel config file.
now i am trying work on the audio part playing and recording. my custom board have McBSP1 as audio interface to TPS65930 controller. but in beagleboard McBSP2 as audio interface, so that i had made configure to McBSP1 instead of McBSP2. audio was playing fine. incase of audio recording i got error. #arecord -t wav -c 2 -r 44100 -f S16_LE -v test.wav Recording WAVE 'test.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Stereo Plug PCM: Hardware PCM card 0 'omap3beagle' device 0 subdevice 0 Its setup is: stream : CAPTURE access : RW_INTERLEAVED format : S16_LE subformat : STD channels : 2 rate : 44100 exact rate : 44100 (44100/1) msbits : 16 buffer_size : 14280 period_size : 56 period_time : 1269 tstamp_mode : NONE period_step : 1 avail_min : 56 period_event : 0 start_threshold : 1 stop_threshold : 14280 silence_threshold: 0 silence_size : 0 boundary : 1871708160 read error: Input/output error ///////// then it's terminating please suggest me where i have to make changes to record using McBSP1 port, or tell me where is going wrong here. thanks in advance.
