SysBIOS directing all stdout & stdin to UART

Stephen Mansfield

Hello,

I am new to SYS/BIOS.  I am trying to figure out how to direct all printf -- that I believe goes to stdout -- to the UART or SCI on my F28069.  Can someone direct me to where I can find out how to do this?

Best Regards,

Steve M.

    Hi Steve,

    Here's the approach I would suggest:

     - Get the SCI echoback example from the C2000 Control Suite. This example has a SCI driver than you can use in your BIOS app.

     - Once you have a working SCI driver, you can change the System provider (used for System_printf) to SysCallback. The default system provider is SysMin which uses CCS CIO to output prints. I am asking you to use SysCallback module as it allows the application to provide callbacks for SysCallback_putch(), _flush(), etc. functions which are used by System_printf() to output the prints. You can make a call to SCI driver's transmit function in the putch() callback function.

    (SysCallback module cdoc: http://rtsc.eclipse.org/cdoc-tip/index.html#xdc/runtime/SysCallback.html)

    Best,

    Hello Ashish,


    From all of the reading I have done this should work.

    Thanks,
