Broken LaunchPad

Primoz Fiser

Hello!

 

I received my Launchpad on 7th of July. It worked perfectly since yesterday.

I was experimenting with IAR Kickstart debugger, looking at register values when my PC notified me that USB device changed. I disconected the Launchpad and rebooted the PC (Windows Vista). When I tried to load program on microcontroller again it didn't work. It shows dialog window and after about 10sec it says: cannot establish connection. I checked in Windows Device Maneger and under Texas JTAG emulator it displays "This device cannot start. Error code 10".

I tried to connect Launchpad to windows xp and it does the same.

Seems like a hardware issue to me. Can I check my board somehow? I'm pretty shure that FET part of the board is doing something wrong or is eventually busted.

 

Thanks in advance!

    Hi

    I have been playing around with my launch pad for a couple of weeks now, and it has worked great from day 1.

    CCS installed with no problems on my windows 7 64 bit system.

    I was using the launchpad earlier tonight and as I was trying to load some code with CCS I got this alarm:

    Error initializing emulator:
    No USB FET was found

    when I look under device manager I get:

    Unknown Device

    And in the properties for the device I get:

    no drivers loaded for this device

    and

    Windows has stopped this device because it has reported problems. (Code 43)

    When I unplug the launchpad and then replug it in I get

    USB device not recognized

    I reinstalled CCS and still get the same alarms.

    is there a way to reload the drivers?

    it seems like a similar problem to the above post.

    thanks for any help in advance.

    Hi timotet,

    have you tested to connect the Launchpad uisng another USB cable (i.e. one from an external HDD) and on another USB port (i.e. when using a HUB connect it to the PC directly).
