I am using Ulink Pro to debug an cc2538 custom board. The debug
connection is implemented through an 6 pin Tag-Connect header. The
signals are connected according the data sheet of the CC2538 and
ULink Pro. Here are the connections:
CC2538 ---> ULink Pro (J1 device internal)
- JTAG_TMS pin 46 ---> TMS_SWDIO pin 2
- JTAG_TCK pin 47 ---> TCL_SWCLK pin 4
- JTAG_TDO pin 48 ---> TDO_SWO_TRACE_CTL pin 6
- VCC ---> VTREF pin 1
