Why isn't my C2000 device getting any power even though I have the USB-C cable connected to USB1?
Make sure that the USB 5V power and GND jumpers are connected (JP1).
Make sure that the XDS110 5V and 3.3V power
jumpers are connected (JP2).
Can other programming and debug tools (such as an XDS200 debug probe) be used with the F28E12x LaunchPad?
The F28E12x LaunchPad utilizes an onboard XDS110
debug probe in a 4-pin JTAG configuration.
What versions of Code Composer Studio IDE can be used to develop software for the F28E12x LaunchPad?
The on-board XDS110 debug probe is compatible with Code Composer Studio development environment version 6.1.0 and later.
Why can't I connect to the LaunchPad in Code Composer Studio IDE?
Are shunts present on J101 for TCK and TMS?
Is the XDS110 and the F28E120SC MCU powered? Are LED7, LED0, LED6
and LED1 illuminated? For further details on powering the LaunchPad, see Section 2.1.1.1.
If JP1 shunts are disconnected,
the power provided through the USB is isolated from the rest of the board. Make
sure that 3.3V or 5V is supplied to any of the available connectors on the target
side of the isolation.
Is the USB-C cable connected to the PCB and is the USB region
receiving power? Is LED7 illuminated?
The XDS region must be powered
with the 5V from the USB cable. LED7 illuminates when 5V USB power is connected.
The XDS-side 5V to 3.3V LDO regulator requires 5V on the USB side to generate the
+3V3 rail for the XDS110 device.
Make sure that the S2 switch configuration matches the target
configuration being used. Open the Target Configuration file (.ccxml) in Code Composer
Studio IDE. Click on the Advanced tab. In the JTAG / SWD / cJTAG mode field, if
JTAG (1149.1) SWD and cJTAG are disabled is selected, make sure S2 is in JTAG
TDI, TDO mode. If cJTAG (1149.7) 2-pin advanced modes is selected, any S2
configuration can be used. Alternately, a working Target configuration file is
included in the launchxl_ex1_f28e12x_demo project F28E120SC.ccxml. Use this
without modifications.

Why is the serial connection not working?
Are you using the correct COM port?
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 to use.
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 160MHz. If you have
changed the PLL settings or developed your own code, you can recalculate the baud rate
for your specific application. For information on how to do this, see the F28E12x
Real-Time Microcontrollers Technical Reference Manual.
Is the UART channel connection to the debug probe enabled and does this match
the channel configured in software?
The F28E12x LaunchPad provides
options for customizing the use of GPIO35 and GPIO37. In this program, use GPIO35
and GPIO37 as UART signals to establish a serial connection to the debug probe.
Make sure that S2 is configured to the appropriate UART channel for the
application software. For details, see Section 2.1.3.2.
