4. Why is the serial connection not working?
a. Are shunts present on J101 for TXD and RXD?
b. Are you using the correct COM port?
i.
Right click on My Computer and select Properties. Navigate to the Hardware tab in the dialog box
and open the device manager. Scroll to Ports (COM & LPT) and expand this entry. Is XDS110 Class
Application/User UART listed? If so, read the COM number to the right of the entry; this is the COM
number you should be using.
c. Are you using the correct baud rate?Most, if not all, of the examples are configured for a baud rate of
115200 when the CPU is running at 120 MHz. If you have changed the PLL settings or developed your
own code you may have to recalculate the baud rate for your specific application. For information on how
to do this, see the
d. Does the UART channel wired to the debug probe match the UART channel configured in software?
i.
The F28003x LaunchPad provides an option for one of two possible UART channels to be routed to
the debug probe through J101. Ensure that S2 is configured to the appropriate UART channel for the
application software. For details, see
