Hi,

I am currently working on an Uart driver that is using the OMAP-L137 DMA and at some point, it appears that on the Tx side, sometimes the DMA transfer is not started/queued correctly after a davinci_start_dma call that return success.

Is there a way to double check if my request as been corectly queued after the davinci_start_dma call ?

Regards,
