A bit try and error here. If I only follow your first modification to luminar.cfg and not the 2nd modification, no more hang. mymacmini:ftdi xiaofanc$ pwd /Users/xiaofanc/bin/share/openocd/scripts/interface/ftdi mymacmini:ftdi xiaofanc$ cat luminary.cfg # # Luminary Micro Stellaris Evaluation Kits # # http://www.luminarymicro.com/products/evaluation_kits.html # # There are a number of evaluation kits for Stellaris Cortex-M3 chips. # Currently they all bundle ftdi based debug support. When that is # used (instead of an external adapter), use this config file in one # of these two modes: # # - Eval board debug ... debug of the Stellaris chip via port A. # # - Other board debug ... same thing, but the board acts as a debug # adapter for another board (using a standard ARM JTAG connector). # The Stellaris chip stays in reset. # # Those support both JTAG and SWD. SWD is an ARM-only two-wire debug # protocol; in 2009, OpenOCD does not support SWD. # # Port B of the ftdi chip is normally used as a serial link to the # Stellaris chip. On most boards (but not older LM3S811 eval boards), # when SWD is used Port B may instead be used to read low-bandwidth # "SWO trace" data, including so-called "printf style" output from # firmware via the ITM module as well as profile data. # interface ftdi ftdi_device_desc "Stellaris Evaluation Board" ftdi_vid_pid 0x0403 0xbcd9 ftdi_layout_init 0x00a8 0x00eb ftdi_layout_signal nSRST -data 0x0020 -oe 0x0020 mymacmini:lm3s1968 xiaofanc$ ~/bin/bin/openocd -f ~/bin/share/openocd/scripts/board/ek-lm3s1968_mpsse_icdi.cfg Open On-Chip Debugger 0.6.0-dev-00448-gac053a2 (2012-05-09-19:01) Licensed under GNU GPL v2 For bug reports, read http://openocd.sourceforge.net/doc/doxygen/bugs.html Info : only one transport option; autoselect 'jtag' 500 kHz Info : clock speed 500 kHz Info : JTAG tap: lm3s1968.cpu tap/device found: 0xffffffff (mfg: 0x7ff, part: 0xffff, ver: 0xf) Warn : JTAG tap: lm3s1968.cpu UNEXPECTED: 0xffffffff (mfg: 0x7ff, part: 0xffff, ver: 0xf) Error: JTAG tap: lm3s1968.cpu expected 1 of 1: 0x0ba00477 (mfg: 0x23b, part: 0xba00, ver: 0x0) Warn : Unexpected idcode after end of chain: 608 0x7fffffff Error: double-check your JTAG setup (interface, speed, missing TAPs, ...)
