5 Frequently Asked Questions

  1. Why isn't my C2000 device getting any power even though I have the USB-C cable connected to USB1?
    1. Make sure that the USB 5-V power and GND jumpers are connected (JP1).
    2. Make sure that "ENABLE +3V3 LDO" jumper header (J16) is populated with a jumper. This generates the 3.3-V rail for the board from the 5-V USB power.
      1. To avoid contention on the 5-V rail, make sure that the "ENABLE +5V0 BOOST" jumper (J17) is disconnected when supplying 5 V through the USB.
  2. Can other programming and debug tools (such as an XDS200 debug probe) be used with the F28P65x LaunchPad?
    1. The F28P65x LaunchPad utilizes an on-board XDS110 debug probe in a 4-pin JTAG configuration.
  3. What versions of Code Composer Studio IDE can be used to develop software for the F28P65x LaunchPad?
    1. The on-board XDS110 debug probe is compatible with Code Composer Studio development environment version 6.1.0 and later.
  4. Why can't I connect to the LaunchPad in Code Composer Studio IDE?
    1. Are shunts present on J101 for TCK and TMS?
    2. Is the XDS110 and the F28P650DK9 MCU powered? Are LED1, LED7, LED3 and LED6 illuminated? For further details on powering the LaunchPad, see Section 3.1.2.
      1. If JP1 shunts are disconnected, the power provided through the USB is isolated from the rest of the board. Make sure that 3.3 V or 5 V is supplied to any of the available connectors on the target side of the isolation.
    3. Is the USB-C cable connected to the PCB and is the USB region receiving power? Is LED1 illuminated?
      1. The XDS region must be powered with the 5 V from the USB cable. LED1 illuminates when 5-V USB power is connected. The XDS-side 5-V to 3.3-V LDO regulator requires 5-V on the USB side to generate the +3V3 rail for the XDS110 device.
    4. Make sure that the target configuration is set up to use JTAG in 4-pin advanced mode. Open the Target Configuration file (.ccxml) in Code Composer Studio IDE. Click on the Advanced tab and select JTAG (1149.1) SWD and cJTAG are disabled. Alternately, a working Target configuration file is included in the launchxl_ex1_f28p65x_demo project "TMS320F28P650DK9.ccxml". You can use this without modifications.

  5. Why is the serial connection not working?
    1. Are you using the correct COM port?
      1. 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.
    2. 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 200 MHz. 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 TMS320F28P65x C2000 Real-Time Microcontrollers Technical Reference Manual.
    3. Does the UART channel wired to the debug probe match the UART channel configured in software?
      1. The F28P65x LaunchPad provides an option for one of two possible UART channels to be routed to the debug probe. Make sure that S2 is configured to the appropriate UART channel for the application software. For details, see Section 3.3.2.
