Hi guys,
I'm working on dm368 davinci processor, in a board that is acquiring video from 2 cameras and 1 audio channel (mono), from a microphone.
I'm using dvsdk_2_10_01_18 with linux kernel patched from UDWORKS (2.6.18_pro500-davinci_evm-arm_v5t_le).
I'm basically using the mcvip framework to acquire audio / video data in my application.
Meanwhile the video acquisition seems to don't have any problems during long time tests, I see problems on the audio acquisition.
After some hours of acquisition (it seems to depend from the cpu load, but I'm not sure), the audio samples on the lonely audio channel I have get silent (I read only 0x00 bytes or 0xFF bytes).
About the hardware: the audio is taken from a tvp5158 via I2S line.
Has someone seen an issue like this before?
Thanks
bye Daniele
