Every year or so I try openocd, and still no joy. Actually, seems the script and config stuff has all finally matured/stabilized, so I'll assume I can make it work w/o too much pain, after I fix this hang:
I have a vanilla lpc2138 on an ARM-USB-OCD, that seems to fire up ok using the built-in configs in /usr/share/openocd. Hangs forever on write_image: steve@dystant:~/projects/clients/zonge/DNT/NT-32/firmware/arm/main$ openocd -f openocd.cfg Open On-Chip Debugger 0.4.0 (2010-10-08-15:42) Licensed under GNU GPL v2 For bug reports, read http://openocd.berlios.de/doc/doxygen/bugs.html RCLK - adaptive jtag_nsrst_delay: 200 jtag_ntrst_delay: 200 srst_only srst_pulls_trst srst_gates_jtag srst_open_drain Info : RCLK (adaptive clock speed) not supported - fallback to 500 kHz Info : JTAG tap: lpc2138.cpu tap/device found: 0x4f1f0f0f (mfg: 0x787, part: 0xf1f0, ver: 0x4) Info : Embedded ICE version 4 Info : lpc2138.cpu: hardware has 2 breakpoint/watchpoint units flash write_image erase unlock Main.elf 0 Just for completeness, the the config script follows.
