AWR1843BOOST: AWR1843BOOST Baudrate

HARKRISHAN SINGH DADHWAL
Prodigy 200 points
Part Number: AWR1843BOOST

Hello,

I am connecting TM4C1294XL Launchpad with AWR1843BOOST with the former acting as a serial to ethernet converter. My launchpad is working fine as a serial to ethernet converter but when I connect my AWR 1843BOOST to the launchpad I do not get the output. One probable reason I could find is that the baud rate of AWR1843BOOST (data rate) is 921600 whereas the launchpad supports a max. baud rate of  230400

Can anyone guide me in changing the baud rate of any of the boards so that the two boards communicate?

    Hello Harkrishan,

    mmWave SDK v3.4 showcase the max UART baud rate of 3125000. Please refer the mwmave SDK user guide pdf (section 3.3.1)

    Now in the mmw demo source :

    mmw_cli.c : MmwDemo_CLIConfigDataPort() function changes the buad rate as requested over CLI.

    You can hardcore this in your application. Here is the code snippet wrt to mmw demo of SDK v3.4

    mss_main.c: MmwDemo_platformInit() -> config->loggingBaudRate = 3125000;//921600;

    This changes the baud rate of logging UART, same way you can change command UART baud rate as well.

     

    Regards,
