Hi TI,
When I use OMAP4470 DMIC to capture audio by tinycap, the kernel show the errors as below at the beginning:
<6>[ 31.683319] DMA synchronization event drop occurred with device 67
<6>[ 31.706115] DMA synchronization event drop occurred with device 67
<6>[ 31.733551] DMA synchronization event drop occurred with device 67
<6>[ 31.767608] DMA synchronization event drop occurred with device 67
<6>[ 31.857482] DMA synchronization event drop occurred with device 67
<6>[ 31.867889] DMA synchronization event drop occurred with device 67
<6>[ 31.900054] DMA synchronization event drop occurred with device 67
<7>[ 41.909057] ALSA sound/core/pcm_lib.c:1854 capture write error (DMA or IRQ trouble?)
Is it a problem?
