Hello
I'm using mcbsp1 of omapl138 on a custom board. I wanna do a data loopback using edma3 on the same board. I've changed the mcbspSampleMaster project shipped with the pspiom driver package and created two streams succesfully and the buffers are allocated successfully. But reclaiming those buffers hangs forever. I'm using the following mcbspchanparams for the two streams. What could be the reason for the reclaim waits for the buffer forever. why it couldn get the buffer that has been issued.
/**< settings to configure the TX or RX hardware sections */
