Hello,

I am here to report, and also to try to fix my problem, that LPC-Link is not working under Ubuntu 12.04 x64 beta 2.

This ubuntu is my main OS, there is no VM.

I have installed the Code Red IDE properly and it is working just fine.

When I do debug, the LPC-Link is initialized but no debug happen.

Follow below some logs to two commands on the LPC-Link through terminal:

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

My Target+Link setup works fine on my vmware machine running WinXP on this same computer.

Please, any help is welcome, I have done searching and found nothing that could fix this problem.

EDIT WITH THE SOLUTION:
Link (ln -s) the <lpcxpresso/bin>/libusbX.so.X to the /lib system folder.

file /lib/udev/rules.d/91-permissions.rules.

That file is not present on my Ubuntu 12.04 installation. Perhaps you installed something else that created that file?

I'm not sure it is the same case, but I faced problem with usb device permissions. They were set to 0664 (not writable to anyone except root) even though it should be 0666 according to /etc/udev/rules.d/85-code-red.rules (the file installed by LPCXpresso intaller).
The reason is simple. There is another rule
SUBSYSTEM=="usb", ENV{DEVTYPE}=="usb_device", MODE="0664"
in file /lib/udev/rules.d/91-permissions.rules.
This second file is processed later and in result udev rules created by Code Red are completely useless.

The workaround is simple. I changed the name of file from 85-code-red.rules to 99-code-red.rules.
Now permissions are properly set to 0666 and in result the usb device is writable for everybody.

This is still broken for me. I had recently upgraded to ubuntu 12.4 (from having a working system before). I upgraded to lpcxpresso_4.3.0_1025 after discovering that I couldn't connect.

I have the 32 bit compatability libs installed, but no libusb in /lib.

i tried the soft-link option, but according to ltrace/ 'too many levels of soft-link', so I did a copy.

ltrace now shows me that i have a permissions problem - when using dfu-util to download the debug firmware.

Is there a udev option that needs setting to fix permissions for the usb? i didn't see it on the install instructions (but I could have missed it...)

Edit: the gui will connect to the debug probe now, but I'm not sure if I needed to run the firmware download as root in order to facilitate this...

This worked for me immediately:

sudo apt-get install libusb-1.0-0:i386

Hi!
I also had that problem. I'm running Ubuntu 12.04 final 64 bit withe the 32bit libraries.

Quote: fanl

$ sudo cp /usr/local/lpcxpresso_4.2.2_238/lpcxpresso/bin/libusb-1.0.so.0 /lib

That also fixed it for me. Thanks for that!

Installation of the 32-bit compatibility libraries is documented here:
http://lpcxpresso.code-red-tech.com/LPCXpresso/Linux
Are you saying that you followed these instructions and it didn't work?

Oh, sure, ln -s is the right thing to do.

Thanks for the tips.

This is what i thought actually :P
better ln -s it though

Use ltrace next time, it shows exactly which libs it it fails to load
(Those progs in lpcxpresso/bin use dlopen() for shared libs)

I cant believe but I have fixed it.

The problem was with the libusb 32bits compatibility, since I am running a x64 ubuntu.

The solution was extremely simple:

$ sudo cp /usr/local/lpcxpresso_4.2.2_238/lpcxpresso/bin/libusb-1.0.so.0 /lib

This command will copy the 32bit libusb that came along with lpcxpresso to the lib path. On ubuntu 12, the folder /lib is the default for 32bits lib.

First, make sure you have ltrace installed.
Then, run this and post the output here:

ltrace -s 255 ./crt_emu_cm3_nxp -info-emu -wire=winusb

Also, while at it, do this, and post the results as well:

ldconfig -p | sed -n -e 's/.* \(.*libusb\.so.*\)/\1/Ip' | xargs file -L

P.S. I am in the worse problem than you atm, trying to make this shit work at FreeBSD lol

Thank you for your support. I'll report to ubuntu developers.

Anyway, I'd like to leave an open question here, if anyone else is having similar trouble, please post, since more samples of this trouble would help on troubleshooting it.

At.

Check your libs, my guess is that you dont have 32 bit libusb on your 64 bit ubuntu. Run this:

ldconfig -r | sed -n -e 's/.* \(.*libusb\.so\)/\1/p' | xargs file

and post the output.

I recommend that you report this to Ubuntu as it is obviously a regression from their previous releases (and it is a beta, so they should be happy to receive this feedback). Note that this does work on Ubuntu 9, 10 and 11.
