Any thoughts??

Very true.  Thanks!

Glad to hear that you now have the debug tools working.

Regarding your link issue, I suggest that you create a new thread with a relevant subject - otherwise your question (and any responses) are going to be hidden from most users at the end of this very long thread!

Regards,
CodeRedSupport.

A complete reinstall of 3.8.2 after rm'ing /usr/local/LPCXpresso has fixed the problem.  so far so good.  Except for one issue:

The Link Alias for the RamAHBCan is no longer defined???

Thanks very much for all of your help!

p.s. somebody has chmod 777 on all files in that directory. Do not do this, as the installer explicitly sets the correct permissions on the files, and if you change them, then things will start failing.

As I suspected, the permissions on many of the files have been changed, and this is causing your problems. The dates of many of the files don't seem to match those on my system either.

Specifically, all of the crt_emu* files and dfu-util should have the "s" bit set (which allows them to run as the owner of the files - in this case root). This is set by the installer, and so the permissions have been changed after the install. If this is not set, you will get the problems you are experiencing.

The quickest way to resolve this is to uninstall LPCXpresso, and ensure the whole of the /usr/local/LPCXpresso directory is removed. Then download the latest (v3.8.2) and install it.

Once installed, you will see that crt_emu_* and dfu-util will have the "s" bit set in the directory listing - the permissions will be rwsr-sr-x.

I'm sorry, what questions would you like answered?  I must have missed it (them)

Actually crt_emu_cm3_nxp has the "s" bit set by the installer, and so should already being run (effectively) as su already.

So have you changed the permission on the file? Please
ll /usr/local/LPCXpresso/bin
and post the results. If the tools have not got the correct settings, this would explain most of your issues.

[lpcware]

Content originally posted in LPCWare by CodeRedSupport on Wed Feb 09 07:11:41 MST 2011
In that case, try
"sudo crt_emu_cm3_nxp -info-emu"

Please also answer the other questions I asked.

Having booted LPC-Link manually (using dfu-util), can you run
- crt_emu_cm3_nxp -info-emu
and post the result

Also, (again having booted LPC-Link) what happens when you start a debug session from within LPCXpresso.

Also, can you summarise what you changed on you system when it stopped working.

It just keeps getting worse... Installed ia32 - 32-bit compatibility for 64 bit ubuntu and now I get "Initializing LPC-Link" timeout.  However, if I  open a terminal, su and run:

dfu-util -d 0x471:0xdf55 -c 0 -t 2048 -R -D LPCXpressoWIN.enc

The device re-numerates as the 1fc9:0009 device.  What gives??  Everything was working flawlessly under Ubuntu 10,4 for 2 months!!! And then poof it all turns to shiz without changing any OS or tools or hardware!!!!!!

Sincerely,

Frustrated!!!

In the course of all this, do you (still) have a viable libusb.so installation? Disconnect, then reconnect the USB cable to power-cycle the device. When it powers up, it will enumerate as a DFU device. Navigate to your LPCXpresso installation bin directory (typically '/usr/local/LPCXpresso/bin'), and issue:

Ignore the Broken pipe warning, this output is an example of a successful. download and boot of the software probe on the LPC-Link. If the probe is active, the debug utility should find it. Issue the following command-line:

user@Ubuntu-laptop:/usr/local/LPCXpresso/bin$  crt_emu_cm3_nxp -wire=winusb -info-emu

This shows the LPC-Link in the device list. The software probe is active, and the LPCXpresso debug utilities can talk to it. It doesn't mean the probe can gain debug control over your processor, if there are other issues. The cause and effect of contributing issues is covered earlier in this thread.

Well... I installed latest ubuntu patches... 10.4 LTS Lucid Lynx and completely removed lpcexpresso... and reinstalled 3.8.2.129.

Drum roll....

Now I get a constant "No emulator or board available" dialog.  Shorting jp2.10 no longer makes any difference.  Just for fun, I reconnected the jumpers to the lpc134x on the LPClink.  I get the sam "No Emulator connected." dialog.

  Any pointers?

Install: LPCXpresso 3.8.2-129
OS: Ubuntu 10.04.1
Target: LPCXpresso1768 via LPC-Link

I performed a new install of LPCXpresso 3.8.2-129, and downloaded your .axf file multiple times without trouble.
I don't have your hardware, and there's no telling what's going on with your installation. I recommend you download the most recent LPCXpresso build, then uninstall/reinstall the product.

I found an issue with the rest circuitry on my target hardware so I'm able to program flash reliably every time so I assume the clocking is correct on my hardware.

I am still, however, unable to ever run the debugger without a segmentation fault.  Is this a segmentation error in gdb itself?  I guess I'll try wiping out the lpcxpresso install and installing clean??

I was afraid you'd say that; are there any pins on the lpc1754 that could cause funkiness such as I'm seeing if they were held static through a reset?  I've attached the page of my schematic with the LPC1754.

Thanks for the reference, but I know how to change the clock speed in my code, what I'm asking is, what EXACTLY is the format of the entry field in the lpcxpresso IDE under Run Config->Debug-xtal frequency and PLL value???

Thanks for sending the code through.

I've tried loading and running the code several times on a board here and no problems found. This would seem to indicate a hardware problem (though admittedly as I have a different board to you, there is a chance that you are doing something in the software that is upsetting things on your board).

One thing that you could try is to create a new workspace, load the standard  LPC17xx CMSIS project in from the examples directory, and then use the project wizard to create a new C project. Can you then successfully download this to your board and run it?

You also asked about  xtal frequency and PLL values earlier. Suggest you take a look at the following FAQ:
