Hello,

Please refer to the McBSP ping-pong buffering example in section 18.3.4.4.1 of the OMAP-L138 Technical Reference Manual for guidance on modifying the loopback example to work in ping-pong mode.

OMAP-L138 Technical Reference Manual

There is also a McBSP ping-pong example for the C64x device by Spectrum Digital that you may refer to.

Hope this helps.
