Hello, Dominic
I wonder whether I can use the schema of the JTAG in your
document "Open On-chip Debugger" to make a JTAG interface. Then I
can use it to debug my evaluation kit in openOCD, right?
Thanks & Regards!

Well, you could use the serial ISP to bootstrap the programming routines
into RAM. That's how some serial ISPs work even for internal flash. The
ST10 as an example loads something like 16 bytes from the serial port to a
fixed memory location and then jumps to it. The serial ISP process is a
set of step loading larger programs into RAM until you have one that can
handle the flash programming. It's a lot more straightforward than I just
made it sound.

You need to :-
1) Get Jim Lynch's latest tutorial. Search elsewhere in this group for
where to get it from. Make sure it is the version based on OpenOCD and
you use the exact version that jim mentions. You can however use the
latest version of OpenOCD that dominic gave you a URL too.
2) Adapt Jim's Led Flashing program to suit your chip, this will at
least need modification of the Linker scripts. Make sure you try the
running from RAM bit and skip past the running from Flash bit.
Does anybody in this group have or know where to get a linker script
for Kevin's chip ????? It may be in the files section of this group.
3) Once you have LED flashing then your Toolchain is working. Then you
can move on to look at using OpenOCD to write to your flash.

Hello,
the OpenOCD requires a configuration file, specifying the JTAG interface to
use, the layout of the JTAG scan chain, the target connected, and other
things. By default, it tries to open 'openocd.cfg' in the same
directory as
the binary, but you can select the configuration file with the '-f
config.file' command line switch.
This means that double-clicking wont work, unless you use a link specifying
the appropriate command line arguments.
Regards,
Dominic

Dominic,
I still meet a problem when trying to run the version you
recommended. The problem is where I should run this version, cygwin,
DOS, or just double click it? I tried all of them, but none worked.
And the problem with the version I downloaded before is that one
headfile missing, exactly ftd2xx.h, whose directory is
openocd\src\jtag. And this version was downloaded from the website
showing as follows: http://prdownload.berlios.de/openocd/openocd-cygwin-ftd2xx-
20060213.tar.gz
Best Regards

I guess this was the last release from the files section, precompiled for
Cygwin with support for FTDI FT2232 based JTAG interfaces.
It comes with all the files necessary and you don't have to build it
yourself.

Sorry to ask so many question. One more. ^_^
Does the openOCD support flashless LPCs?
Thank you indeed!
