Hi Group,

I am new to embedded linux and hence stuck trying to get my setup
working.
My problem is every so often when I try and lunch openocd I get the
following error output.

Start a New Thread

change your config file to:
ft2232_device_desc "Olimex OpenOCD JTAG A"
And use another power source for your board.

Hey Harrie,

Thanks for the suggestions. But the problem still persists.
For powering my LPC-MT 2106 development board I am now using a 9V 2.2A
dc block. The documentation for the board recommend 6Vac/9Vdc.

I also changed the ft2232_device_desc to "Olimex OpenOCD JTAG A" as
advised but no show.

Is there anybody in this group that uses this dev board and debugger
combination.
There is a jumper label JRST on the board that I can't find in the
schematic diagram.

The only two pin jumpers that I can see in the schematic diagram is
the DEBUG and the BSL.

Many thanks in advance

Hi All,

Can any confirm which svn version of openocd is being used.
I am still having problem trying to connect my dev board to my olimex
usb arm debugger.
Many thanks in advance.

Hi All,

Is there anyway of testing Olimex LPC-MT2106 development board in
isolation?
What I want is tool that will allow me to program the flash with a
program that exercises the LCD and LED.
This will allow me to eliminate the dev board from my list of suspect
in my setup

Ola Oni

IIRC the LCD on that board is connected to the 2106's ETM pins and cannot,
therefore, be accessed while debugging with a JTAG adapter connected.

Have you tried using ISP?

Hi Paul,

Thanks for your response.
I am not sure I understand the contents of your Posted message, please
remember I am new to the whole Linux environment development.

What do you mean? IIRC the LCD on that board is connected to the
2106's ETM pins..
Accordingly to the schematic diagram P0.17 to P0.21 is connected to
the Jtag connector
While P0.4 to P0.7 is connected to the LCD data bus and P0.22 to P0.24
are connected to the LCD control line namely E, RS, and R/W respectively.
Let me know if you want me to send you the schematic diagram for your
reference.
And just in case I have missed something in your message what is IIRC
and am I correct in understanding ETM as Enable Trace Module.

Which application do you recommend that is free for ISP.

Regards
Ola

Hi Paul,

I think I now understand your message after doing a Google search on
IIRC I found that it is an acronym for "If I Recall Correctly".
The schematic diagram can be view using the following url.

Many thanks in advance.

Hi,

You cannot control the RS, R/W, and E signals from the LPC2106 as these are
connected to TRACECLK, PIPESTAT0, and PIPESTAT1. Unfortunately, with
primary JTAG enabled, the ETM is also enabled and thus whatever you do to
try to control P0.22 through P0.24 won't work because the ETM is hardwired
to them (with JTAG enabled).

Hence, the *only* way to display data on the LCD is to program the
application over JTAG or ISP, then reset the part without JTAG debug enabled
and see if your LCD works.

It took me about 30 minutes to do this, but then I did have the code written
and working on an LPC-2138-MT and many other boards.

As for ISP, I don't know, I never use ISP to program NXP parts.

Hi Paul,

Based on your message about you having flashed this board (lpc-mt
2106) in the past I was wondering if it was possible for you to give
me your binary file, so all I have to do is find an application that
will allow me to program the on board flash through ISP.

I don't need the code just the hex file, as I can write one when I am
up and running with the board.

My main objective is to get my olimex-arm usb JTAG debugger working.
As for now what I noticed is that openocd is not detecting the targets
power hence the error.

Error: JTAG communication failure, check connection, JTAG interface,
target power etc.

This error is consistent whether the debugger is connected to the
target or not.
Regards
Ola
