Hanief,
The DM642 EVM has an onboard DUART (TLC16C752). This means there are two UARTs each. UARTA is mapped at 0x90080000-0x90080007 and UARTB is mapped at 0x90080008-0x9008000F. This information is available in the DM642 EVM Technical Reference Manual. Also, SPRA882(x) (Hardware and Software UART Device Drivers) may help you as well.
I recommend you familiarize yourself with the TLC16C752 (SLLS405A) and EVM schematics to gain a better understanding of the overall DUART interface.

Hope this helps you...

Hi everyone,

Gustl,
Are you sure it's spru633? That one seems to be about CNG Algorithm.
Mikedunn,
You're right that DM642 has an on board dual UART interface. So the
way to use RS-232 is by using UART is it? I wish there's a similar
guide for DM642 as the DM6446 though.
Cheers,
Hanief

FYI - the DM642 has an on board UART.

Hanief,

Oops - I had a brain short circuit on which problem that I was working on.
Refer to the DM642 EVM documentation for info on the RS232 port.

I apologize for the confusion.

The normal way to get info is:
1. goto ti.com.
2. search for tms320dm6446.
3. goto the 'product folder'.
4. click on 'technical documents'.
5. look through the list carefully. The following is probably what you are
looking for:

Hi,

spru633b is about a RS-232 using a MCBSP. I have done this with a 6711
and a 6713. I don't know if it works with a DM642.

Hi everyone,
Can anyone enlighten me on how to program the RS-232 port on a DM642 EVM? Is it using McBSP? I've read spru580 but it doesn't help me much. There doesn't seem to be much documentation on it.
Thanks.
