How to use McBSP1 as UART ?

Other Parts Discussed in Thread: DM3730

Hi all,

we are developping our custon board based on DM3730 with linux kernel 2.6.39. We need to use McBSP1 as an UART... How can I configure this linux kernel to be able to use MCBSP1 as TTY?

Thanks in advance,

Best Regards,

Pierre

    Pierre,

     

    I don't think that the McBSP can be used as a true UART. There are ways to "emulate" UART via McBSP but this is not supported by the PSP drivers.
    The following app notes does show how the McBSP of some C6000 devices can be used as UART:

    The DM3730 McBSP is likely to be different to the one referenced in SPRA633C.

    Hope it helps,

    Anthony
