Frequently Asked Questions
5 Frequently Asked Questions
1. Can other programming and debug tools (such as an XDS200 debug probe) be used with the F28003x
LaunchPad?
a. The F28003x LaunchPad utilizes an on-board XDS110 debug probe in a 2-pin cJTAG configuration.
cJTAG only uses the TMS and TCK pins of the debug probe. TDI and TDO are present on tJ101 and
can be connected to a debug probe through jumper wires, if necessary.
2. What versions of Code Composer Studio can be used to develop software for the F28003x LaunchPad?
a. The on-board XDS110 debug probe is compatible with Code Composer Studio development
environment version 6.1.0 and later.
3. Why can't I connect to the LaunchPad in Code Composer Studio?
a. Are shunts present on J101 for TCK and TMS?
b. Is the XDS110 and the F280039C MCU powered? Are LED0 and LED1 illuminated? For further details
on powering the LaunchPad, see
i.
If JP1 shunts are disconnected, the power provided through the USB is isolated from the rest of
the board. Ensure that 3.3 V is supplied to any of the available connectors on the target side of the
isolation.
c. Is the USB-C cable connected to the PCB and is the USB region receiving power? Is LED7 illuminated?
i.
The USB region must be powered with the 5 V from the USB cable. LED7 will illuminate when 5V
USB power is connected. TheUSB isolation chip requires 5 V on the USB side to operate and pass
the signals across the isolation barrier.
d. Ensure that the target configuration is set up to use cJTAG in 2-pin advanced mode. Open the Target
Configuration file (.ccxml) in Code Composer Studio. Click on the Advanced tab and select cJTAG
(1149.7) 2-pin advanced modes from the drop-down labeled JTAG/SWD/cJTAG Mode. Leave the Target
Scan Format as OSCAN2 format. Alternately, a working Target configuration file is included in the
launcxl_ex1_F280039C_demo project "TMS320F280039C_LaunchPad.ccxml". You can use this without
modifications.
