Hello,
I’ve been trying to get the write FIFO to work on the McAsp on a OMAP-L137 (from the C6747 core). I have set the WFIFOCTL register (with the WENA bit set last as described in the user guide). Also this is set before the transmitter is taken out of reset.
I then write five times to the XBUF[0] register expecting to have five transmissions. But I only get two. It is as if the writes are not being FIFO’d. Am I writing to the correct register? Or is there some set up I am missing?
Cheers,
John.
