Hi I'm new to ARM processors and JTAG but have some previous experience
with other micros like AVR's.
I am currently trying to program my LPC2138 on my custom made board with an
Olimex ARM-USB-TINY JTAG adapter. So far I've managed to get almost
everything working, except for the config/script files for flashing to device
with JTAG.
When I tell it to program, the console outputs this:

User: target.c:436 target_process_reset(): Timed out waiting for halt after

My lpc2138_flash.script file looks like this:
arm7_9 dcc_downloads enable
wait_halt
sleep 10
poll
flash probe 0
flash erase_sector 0 0 0
flash write_image 0 main.bin 0x00
reset run
sleep 10
shutdown
It looks like it detects and erases the memory fine...but the write_image line
does nothing. I also get the same result when I take the line out. If I try to
use the older "flash write" it says unknown function and if I use "flash
write_bank" same thing happens as write_image.
Anyone know what could be wrong?
flash write_image doesn't do anything

Okay I got the console output I wanted, but still haven't gotten my code to
work.
I changed the flash write_image line to: "flash write_image main.hex" and got this:

So it looks like it worked....but nothing is happening on my board.

Hi
Just an observation; I notice you are using OpenOCD 1.0 of October 2008. I'm using version 0.4.0 of February 2010 under Ubuntu. I see 1.0 was a branch from the main OpenOCD development. The commands you list are quite a bit different from the ones I use to program an LPC2138 which are:
..............
# erase first bank only
echo "erasing:"
ocd_flash erase_sector 0 0 1
sleep 20
# erase all banks
ocd_flash erase_sector 0 0 26
sleep 20
## flash erase_address 0 0
# blank check
echo "blank check:"
ocd_flash erase_check 0
sleep 20
# write
echo "writing:"
ocd_flash write_image Flt12.hex 0x0 ihex
.................

Oh that makes a lot more sense. I noticed that and was wondering how I had
version "1.0" from 2008 where as the latest version is 0.4.0. That explains
things... I just used the out-of-the-box installation that Olimex provided.
On a side note I figured out how I can program it but it's a pretty weird procedure I came up with. It goes:
1. Device Off, Plug in JTAG Interface
2. Download program, wait until it times out
3. Press Reset
4. Remove JTAG
5. Toggle Power
Does everyone have to remove their JTAG interface from their boards in order to run their software?

Yes I found there is an order of doing things to make it work. Assuming JTAG is
already plugged in, I:
1. Power up LPC board
2. Unplug USB to JTAG from PC, wait, plug it back in
3. Press reset on LPC board
4. From terminal prompt run "sudo openocd -f program-lpc2138.cfg"
Step 2 only needs to be done the first time (probably related to Ubuntu recognising the USB port). Subsequent iterations only require step 3 and 4.
