Lpc2000

I've been ignoring this problem for too long.  It's time to
determine if everyone has experienced it or if it is something I'm
doing.
  I'm using gcc, gdb/Insight, and Macraigor's Wiggler & OcdLibRemote
to build and debug programs running from RAM on a Nohau LPC210x TESTER
Board.  A majority of times when I try to connect to the LPC via
OcdLibRemote from gdb/Insight, OcdLibRemote reports "Cable
Disconnected" and gdb/ Insight does not connect.  Additional attempts
to connect to the same OcdLibRemote session fail within gdb/Insight
even though OcdLibRemote reports success.  The whole thing will
eventually connect after multiple attempts of exiting both
OcdLibRemote & gdb/Insight, and various pressings of the RESET button
on the Nohau board.
  Another issue I remember while writing this is that once connected
and debugging with Insight, it is possible to step through and debug C
source code but not possible to view the underlying assembly code.
  Both of these problems exist for multiple versions of gcc and gdb/
Insight.  So for both issues, has anyone else had either problem and
importantly, have they been able to find a resolution?

Thanks for any suggestions and help you may provide.
-Bill Knight

The Nohau board, cable or Wiggler might have an intermittent fault. It might
be worth seeing if you can borrow units you can swap, to isolate the
problem. Or, try flexing the various units to see if that affects things.
It's quite easy to remove the case of the Wiggler, by levering the halves
apart with a screwdriver.

This is the same problem I had.  Check the parallel port mode.  It should 
be EPP.  The wiggler doesn't like the other high speed modes.

I had more or less the reverse problem.  I can't get it to step through C 
code.  I keep getting complaints about not being able to write 
breakpoints.  I can single step through assembly just fine though.  Mind 
you, I'm doing that in a GDB monitor window, not in Insight.

What are the options you are using on OcdLibRemote?  I'd like to step 
through C rather than wade through all the underlying assembly.

Does anyone know who runs www.lpc2100.com? It could really do with being 
updated with links to this group, all the great products folks like 
Ashling are putting together, and so on - there's a lot of interest in 
the LPC2100s and lots of FAQs and "Where can I find information on..." 
being asked - I'm tempted to set up my own site and put loads of links 
on and a Google Ads bar at the top to pay for it!

Point taken.  I agree, however I do like to get the most out of even my 
most inexpensive tools :)

I'm looking forward to at some point using embedded trace for instance.

In response to my posting I received a private e-mail from
GalieoSD suggesting I try the demo version of their debugger.
After going to their web site and entering the requested info
I received an e-mail giving a link where the program could be
downloaded.

The download file was in an unregistered, self-extracting version
of WinZip.  And after extracting the files my virus scanner reported
that it had found and removed a virus from 'setup.exe'.

Two seperate attempts to contact the company via e-mail using addresses
in their e-mails to me have been returned with unknown user errors.
The email destinations resolve to mx5.net4india.com

In closing based upon this experience I suggest extreme caution in
dealings with this company.

Hi Bill et al,

I feel it as my duty to also add here that there have been ongoing
scandals with Indian companies offering "low price competitive"
engineering "services".
What's been the case at times and what's not told - is that they take
much longer and use 3 times more staff for these "projects", ending up
costing huge amounts to past victims of these scams.

I get regular unsolicited Emails from India offering those services to my
company as well -- No way Jose ....

I concur with Bill, and suggest extreme caution as well.

  Using OcdLibRemote with a wiggler clone interface, the only times I have 
got 'Cable Disconnected' was when really the cable was disconnected or the 
board not powered up. Main troubles have been when I mess the gdb set up.

  That's weird. However, I have heard that with a number of ARM chips. Have 
you tried connecting nRESET to nTRST? That way the whole CPU starts in a 
predefined way. I mostly use that configuration when possible.

  ???

  That works right for me. Have you tried playing with the compiler 
optimizations?

  The wiggler + remote gdb has indeed some glitches. But that can be said 
of most of the debuggers and tools out there. From our experience, most of 
the time the interface does its job right.

This is supposed to be a list about technical issues related to the LPC2100 family, not a sounding board for anti-Indian (or anti-Australian, anti-US, etc, comments).

Can we please keep it that way?

Michael.

Hi Michael,

Of course we can, I prefer it that way too, proviso no one gets
personal and alleges that I provide "stupid, baseless" information
when I KNOW I have my facts damn well straight......

There was nothing anti-anything, just a word of caution - so maybe
no other companies follow the fate some have here in Oz.

Cheers,
Kris

It seems to be owned by baybeetle@... according to whois. 
lpc2100.org is run by this guy, I think:

OK, got the second problem worked out today.  I have been using a
.gdbinit file for Insight under Cygwin.  If I don't use it and just
connect and download using the GUI, MIXED C and assembly was available
in the source window.  I hacked at the .gdbinit file until I got it
working too.  So for those of you who may be interested, it is
included below.
