Hello, this is my first post and be gentle please. I installed LPCXPRESSO V5 and I am trying to use it with my lpcxpresso lpc1114/302 board (free one) on Ubuntu 12.04. First of all, I cannot find anything in this forum. The Search doesn't work properly and there isn't any category. In my opinion, I will lost my own post

I can run only one time the blinky example (pressed build, debug conf > new debug under the mcu part, and debug and pressed green continue button) but after that I cannot re-debug it. It stopped at 94%. I waited and pressed stop debug but it didn't work. I closed eclipse/lpcxpresso. I tried again and again and I got this message

Actually I used lpcexpresso 1 year ago and It used to work. I don't understand what is the problem.

Check your USB connection - try a different USB cable and also try other USB ports.

@ TheFallGuy,

Thank you for answering. I found a way for debugging/programming, but I have to do every time:

[LIST=1]
[*]Close IDE (LPCXpresso).
[*]Unplug USB.
[*]Run IDE.
[*]Clean your project.
[*]Build your project.
[*]Connect your device.
[*]Right click your project and select Debug As >> Debug Confs
[*]Create a new launch conf. and debug.
[/LIST]
It works for Ubuntu 12.04.

It was a driver/library problem. I get over it with this code:

sudo ln -s /usr/local/lpcxpresso_5.0.12_1038/lpcxpresso/bin/libusb-1.0.so.0 /lib/libusb-1.0.so.0

I am having the same problem with Ubuntu 12.10, newest lpcxpresso v5.1.0. I also tried 5.0.12.

I have not had this problem before, and I have been using these tools for a while now.

I have tried using the commandline tools, and they seem to be working correctly. I can flash and connect using gdb, set breakpoints and stop the program.

I can flash the device from within lpcxpresso, but whenever I try to debug, it is stuck configuring GDB.

It shouldn't be a hardware problem, as I can make it work using the command line.

Does anyone experience the same?

Try deleting the launch configuration. And the start debugging again

I have tried following the instructions used by cagdastopcu, and I still have the problem. I also deleted all the launch configurations and had lpcxpresso recreate them. I have also tried rebooting my machine.

Interestingly enough, I did manage to make it work for a bit after having left it for a while. But after a short time, it failed again. I have always had some problems with connections to the boards, but nothing that could not be fixed by disconnecting and reconnecting the board.

Is there any way to find out what lpcxpresso is doing at the time it is stalling. I cannot cancel the operation, but if I disconnect the board, it reports an error and stops.

I managed to find the error. In fact, it was a hardware problem. I was drawing too much power from the IO pins. The spice model I used for the design must have been wrong. It is working fine now.

I'm having a similar problem, but it goes back to at least v5.0.12. I've tried 5.1.2 and now 5.2.4, all have the same issue, I am on a Mac, using v5.2.4, connected to a custom lpc1756 board.

When I select debug, it correctly writes my app to the flash and the code runs correctly (I have a hardware UART that I use and I can trace a lot with it). However, the debugger never connects and the indicator shows:

Launching MyApp: (94%)

The Debug window DOES appear and the top level heading appears "My App Debug [C/C++ (Code Red) MCU Application]" but the threads never appear. If I terminate the debug session, the RedProbe will be busy, i.e. another attempt to debug will fail asking what device do I want to use and showing a window with no debuggers available. If I unplug the USB cable and replug it on my RedProbe, so I'm back to a working state, I can then run my AttachOnly debug configuration and it works perfectly - attaches and lets me debug my app.

Here's the trace from the download and debug attempt:
