Cannot load driver for CC2511 EMK USB Dongel in Windows 7.

Other Parts Discussed in Thread: CC2511, CC-DEBUGGER, SIMPLICITI

Hi all,

I've just recieved my CC2511 Evaluation Module Kit and went to start trying it out.  I downloaded RF studio 7 and installed it on my Windows 7 computer.  I then installed the TI Packet Sniffer and the IAR Compiler.  I then plugged in the module and it plugs and plays but fails to load a suitable driver.  The device is marked as not working and RF studio cannot see it.  I tried to manually update the driver trying to use the drivers located under the C:\Program Files\Texas Instruments sub folders.  None of which worked.

I'm at a complete loss here, I cannot find anything online and this completely prevents my evaluation.

Any help or guidence would be greatly appreciated.

TIA

Richard

    Try these drivers:

    "Cebal - CCxxxx Development Tools USB Driver for Windows x86 and x64" www.ti.com/lit/zip/swrc212

    The updated driver will allow you to use SmartRF Studio, SmartRF Flash Programmer and SmartRF Packet Sniffer on a Win7 64bit OS.

    Note that the CC2511 USB Dongle comes un-programmed in the kit, so you would need to program it with some suitable software or develop your own code based on e.g. the CC USB Firmware Library ans Examples (www.ti.com/lit/zip/swrc088).

    Hi,

    Thanks for your prompt reply.

    Sorry I forgot to mention I had already downloaded and tried this driver and Windows said it was not correct for the device.  Am I loading it incorrectly?  WHat would be the procedure?

    Thanks

    What software do you have running on the CC2511 Dongle?

    Hi,

    None. I was assuming I could get firmware loaded via the USB.  Is there no bootloader at all?  How would I go about this? I assumed there was a development driver that would then allow me to program the dongel.  Is this not the case?

    Regards

    There's no boot loader on the CC2511, so you will need an external tool to program the device the first time. I recommend that you use the CC-DEBUGGER for that . The debugger will come in handy when you want to develop and debug software for the device.

    Ah, in short I've made a mistake thinking the EMK was going to be programmable out of the box connected by USB right?  You basically saying I cannot use it in RF Studio until I flash it with some kind of firmware and this can be done using TI's CC-DEBUGGER.  Is there any quick start guides on going about this?  I only want to perform a simple test using simpliciti using two of these dongles.  I guess I have the same problem with the USB?

    Regards

    A couple of things:

    Yes, you need the external tool to program the CC2511 device. You will *also* need the external tool to control CC2511 from SmartRF Studio. Studio will communicate with the device using the debug interface, not directly over the USB interface. Actually, you do not need any firmware running on the deivce at all to control it from Studio - everything is handled via the debugger, which translates requests from Studio to debug instructions running on the connected device.

    There is some information in  "CC1111/CC2511 USB HW User's Guide" (www.ti.com/lit/swru082). Note that this document talks about using the SmartRF04EB as the external programmer/debugger, but the CC-Debugger works just as well (it's even a bit easier). The CC Debugger user manual can be found here: www.ti.com/lit/swru197

    So with two dongles, connected to CC-Debuggers, you can use Studio to send and receive packages.

    You can also run SimpliciTI on each dongle. But again - you need the debugger to program the code on the dongles.

    Hi,

    Thank you for your help.  I've now actually taken a second look and realised how much of an idiot I was being.  We didn't want the Development Kit as it contained more than we needed.  The dongle was all we needed but obviously the ability to program it is essential ;)

    I'll placed an order for two CC Debugger/Programmers.

    Thanks Again
