LPC-Link driver is not installed under Windows 7

My LPC1769 LPCXpresso board has just arrived, but I had a hard time making it work on my Windows 7 laptop. I tried on a Linux machine and a Windows XP box, and it works fine there. Here's what happens.

When I plug in the USB cable, the "USB Device with DFU Capabilities" driver is successfully installed, and appears in device manager.

If I understand correctly, the first time I try debug, the LPC-link driver should be installed, at least that's what happens in XP.

But in Windows7, instead of having the LPC-link driver installed, I got a pop up window saying: "Device does not support download"

and eventually the debug session times out.

Please, see below the "boot log".

I tried to run LPCXpresso as administrator, but it didn't change anything.

Does the device appear in Device Manager?

There have also been reports of (broken) 3rd party software 'grabbing' LPC-Link before LPCXpresso can get hold of it. Typical culprits include mouse or keyboard 'extenders'. To try to narrow the culprit down, compare the tasks running on your PC with those running on a system where it works.

Hi,

Is there any solution for this problem? I am running LPCXpresso v7.4.0_229 on a Windows 7 laptop. I am trying to connect the LPCXpresso LPC1115 to my USB port. It is being recognized but when i try to debug it this message appears ,

"LPC-Link (HID) not found.
This could be because it is disconnected, not powered, or already in use"

I am also trying to "Search for any Enabled Emulator" but this keeps appearing,

"No compatible emulators available.
They may be disconnected, not powered, already in use or not compatible with this target".

I have also tried to change the usb ports and re-installed my drivers but same message is appearing. To make sure the board is working fine I have tried it on another laptop. Any Solutions?

What issue?

Please describe exactly what you think is not working, and why. Even better, start a new thread, rather than using a thread with lots of different topics.

      The solution that I find is to interchange the names between the two files LPCXpressoWin.enc and LPCXpressoHS.enc and just ignore the error after. The two files you will find in C:\nxp\LPCXpresso_6.1.0_164\lpcxpresso\bin.

This was tested only on Win7 32bits   ;-)

I removed the device driver following the instructions from Microsoft. Then, I re-installed LPCXpresso, but nothing changed.

I tried installing LPCXpresso on another Windows 7 laptop, and it works there, so it is obviously something messed up on this laptop.

I don't fully understand how LPC-link works, but I suspect it doesn't have any firmware on it, except for the boot loader (that provides the DFU functionality), and when you launch debug in LPCXpresso the first time, the LPC-link firmware is downloaded to the board to the RAM, and it runs from there. On this problematic laptop it seems, there is not even an attempt to update that LPC-link firmware to the board, so LPCXpresso will not find the debugger.

Is there any log file you could look at to see why the firmware update does not take place? I would be more than happy to upload it here.

I would suggest removing the device driver:

Making sure you check the "delete the driver software" box.

When reinstalling the drivers, they can be found in the <install>/Drivers directory

I tried all USB ports, and all are USB 2.0. I also tried different cables, but that didn't help either.

I don't think anything is wrong with the hardware (port, cable), because I installed an XP as a virtual machine with VBox running on this very same Windows 7 laptop, and debugging works perfectly in there.

Try a different USB port. Especially make sure you are using usb2 ports. Also try different USB cables.
