Mcbsp omap3703

Prodigy 60 points

Hi,

Iam using omap3703. Mcbsp is used as a slave, with external clock as the source.

I am trying to send the data via mcbsp to audio codec using pcm test program. DMA is triggered and it sends only 2 bytes of data..but i dont see any activity on the pins(i.e, i dont see any clkx or data being pushed out). Anyone has any input on this.

Thanks in Advance..
