stellaris? lm3s2965 (rev. a) evaluation board and
lm3s6965 (rev. a) evaluation board user’s manuals
note: this addendum only applies to revision a lm3s2965 and lm3s6965 evaluation boards. revision b and
subsequent revisions do not require special procedures when using swd out.
the board part and revision numbers are marked in copper on the back of the evaluation board using the
following format: ek-lm3s2965-a or ek-lm3s6965-a. the last letter indicates the revision number.
the evaluation board (evb) can be used as a usb-to-swd in-circuit debug interface (icdi). icd interface
mode is one of several debugging modes described in chapter 2 of the evaluation board user’s manual. using
the evb in swd out mode requires additional steps compared to jtag out mode. this procedure is not
necessary when connecting to the evb’s on-board microcontroller or when using jtag.
to use swd to connect to an external stellaris microcontroller target:
1) use gdb to flash the small gpio_jtag program into the evb’s memory. gpio_jtag is located in the
stellariswareboardsek-lm3sx965 directory. programming must be done before an external target is
connected.
2) power-down the evb by removing the usb cable.
3) connect the evb to the target board using the 20-pin target cable.
4) re-apply power to the evb while holding the reset switch. the red debug out led remains lit. gpio_jtag
will not execute at this point.
5) connect using gdb. this attempt to connect fails, but the evb exits reset state and the gpio_jtag program
starts running.
6) press the select switch to toggle to gpio mode. the current state is shown on the oled display. once the
microcontroller is in gpio mode, it ignores swd operations.
7) connect again using gdb. you will now be successfully connected to the external target.
