AWR1642BOOST: UART Baud rate

Aleksa Anicic

Part Number: AWR1642BOOST

How to use the max baud rate on UART, which is said to be 3.125Mbps in the reference manual? 

No matter what i do, i get some disfunctional code for baud rates higher than ~1.3Mbps. 

I've found the post post trying to do the same, but the answer there didn't help me.

    Hi,

    Can you give us some background on what you are trying to do?

    Are you trying to increase the UART speed in order to transfer more data from the board to a host?

    What host are you using?

    Thank you

    Cesar

    Aleksa,

    What specific error messages are you getting? As stated in the E2E thread that you referenced, serial terminal programs like Tera Term have a maximum supported rate of 921600. This is also the fastest support rate in GUI Composer, which is the tool used to develop the mmWave Demo Visualizer.

    You can adjust the baud rates for the UART in the following code section below:

    /* Initialize the DEMO configuration: */
    gMmwMCB.cfg.sysClockFrequency = (200 * 1000000);
    gMmwMCB.cfg.loggingBaudRate = 921600;
    gMmwMCB.cfg.commandBaudRate = 115200;

    Regards,
