[SIZE=1]Hello,

I use the LPCxpresso 1769 Board (I have the same problem with the LPC1343) and LPCxpresso v4.0.6 IDE. My system is a Ubuntu 10.04 with Kernel 2.6.38.

By debugging I get the error:
"No emulator or board available. This could be because it is unpowered, unconnected or already in use"

For diagnostics I tries this:

It looks like the [/SIZE][SIZE=1]libusb-1.0.so.0 is not available, but i checked it and it seems to be ok.
Does someone know this problem?

Thank you for help.

[SIZE=2]Ok, reinstalling LPCxpresso solved the problem. Perhaps it was really related to the libusb-1.0.so.0 in the  [/SIZE][FONT=Courier New][SIZE=1]/usr/local/lpcxpresso_4.0.6_131/lpcxpresso/bin[/SIZE][/FONT].
[SIZE=2]Thank you very much for helping.

With you a nice day.[/SIZE]

Where is the libusb-1.0.so.0 that you found? The version that we supply should be located in [FONT=Courier New][SIZE=1]/usr/local/lpcxpresso_4.0.6_131/lpcxpresso/bin[/SIZE][/FONT] .

Note that another user who encountered this found that for some reason they had to install the 32bit compatibility components twice before they got things running....

Might be worth trying this, as well as reinstalling.

[SIZE=1]It is a native installation with 64 Bit. I rebooted more than once.

The 32-bit compatibility components are installed (Packages:[/SIZE][SIZE=1] linux32 ia32*[/SIZE][SIZE=1]).

Is this a native installation of Linux, or are you running under a VM?

I presume that you rebooted after installation?

Is it 64 bit or 32 bit Ubuntu? If 64bit, did you install the 32-bit compatibility components, as per the install instructions?
