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

RCLK - adaptive

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.
Best,
