FRDM KL25Z on Windows 8: FAIL.TXT (TIMEOUT)

Hi all,

I recently bought a FRDM KL25Z board made by Freescale. The USB storage device programmer works on almost every PC but my own! I've installed Windows 8.1 on both machines. When I start Ubuntu on one of the systems (the desktop) the programmer storage device does work so the problem seems to be related to Windows.

All ports on my laptop are USB 3.0, on my desktop some are 2.0, some 3.0. When I plug in the device, nothing happens but a fast flickering green led on the board, if I wait somewhat longer (30 sec) the Windows Explorer window vanishes and reopens but now there is a new file present that is called 'FAIL.TXT' which has the content: 'TIMEOUT'.

Does anyone knows how to solve this?

Device config log:

Device USBSTOR\Disk&Ven_MBED&Prod_microcontrolleur&Rev1.0\02000200240291955EA25EE7&0 was configured.

Hi Tom - Sorry to hear your having troubles. Can you tell me more about how your computers are setup? Is this a dual boot system or are you using a VM?

EDIT We are aware that only the mbed LPC11U24 and mbed LPC1768 currently work with Windows 8 (and 8.1). We are looking into this and will have an update soon.

Hi Sam,

My laptop was just re installed with Windows 8.1 Pro (64bit), it's a standard Sony Vaio Pro including USB 3.0. My desktop has also USB 3.0 but connecting my board to a USB 2.0 port didn't make any difference. I've tried my two computers, different boards, different cables and different ports but nothing made a difference.

Because I really needed to get things working as it's required for a compulsory course I eventually created an Ubuntu Live USB: things worked instant! My laptop doesn't support dual-boot that easy so I installed a virtual machine with Ubuntu on it (VirtualBox) disabled the MBED device in Windows Device Manager and redirected it through VirtualBox to the Ubuntu Virtual Machine: it worked! So it really looks like a software issue to me.

Hi Roberto,

I've installed VirtualBox (as Microsoft's solutions have no USB-support) and disabled the MBED device in the Windows Devicemanager (compmgmt.msc). When the Ubuntu machine is started I attach the USB cable to my board and rightclick the 'Connector' icon in the bottom-left corner of VirtualBox. Here I can select the Mbed device to be recognized by the virtual machine. This works for me.

So what you are saying is that Windows tries to execute something from the device?

Solution : i tried this solution ans its work: launch the editor, use Windows+R, then type

gpedit.msc

and after go to Computer Configuration \ Administrative Templates \ Windows Components \ Search \ Do not allow locations on removable drives to be added to libraries

and activate this option.
