Other Parts Discussed in Thread: CC2540, CC-DEBUGGER

Hi All,

I like to setup CC2540 USB dongle on my laptop running Ubuntu 12.04.  The problem is the usb dongle is not detected as a "ttyA" device. Instead I get below logs in demsg. Any help would be highly appreciated.

$uname -a

    Hi,

    I just tried it on my virtual machine:

    $ uname -a
    Linux ubuntu1204 3.2.0-40-generic-pae #64-Ubuntu SMP Mon Mar 25 21:44:41 UTC 2013 i686 i686 i386 GNU/Linux

    [  154.313963] cdc_acm 2-2.2:1.0: This device cannot do calls on its own. It is not a modem.

    $ ls /dev/ttyACM0

    there seems to be a difference in the USB-id between your USB-stick and mine. have you tried flashing the latest "CC2540_USBdongle_HostTestRelease_All.hex" into the USB-dongle?

    hope that helps

    can I do this on Linux machine?. I don't have windows.

    as far as i know the SDK and all tools are windows only.

    try to find someone with a windows machine to flash the stick.

    btw. all the tools run fine on a virtual machine windows for me...

    Hi Andre,

    Tried on a friends Windows 7 laptop. Packet Sniffer tool could detect the dongle but Flash Programmer does not detect it.

    On device manager, its rightly detected as CC2540 Usb Dongle. Any clue?

    thanks  for your help.

    Hi Ravi,

    how did you connect the dongle to the PC? to flash an image you need to connect it via USB (to power it) and with the CC-Debugger on the debug-port to flash it.

    If the Packet Sniffer detects the dongle it seems to have the sniffing firmware flashed to it which is different from the HCI-firmware.

    have a look at http://www.ti.com/lit/ug/swru270c/swru270c.pdf (especially chapter 5.2) about flashing the dongle...

    Hi,

    I know this post is quite old but ....

    I have a Ubuntu 12.04 running under Virtual box.

    When I plug the CC2540 USB dongle in I get no ttyACM0 device.

    I have the USB enabled for the VM.  Do I need something else for the VM.

    It all works in a WIN7 environment.

    Thanks.

    Hi,

    Do you have the VirtualBox Extension Pack installed (https://www.virtualbox.org/wiki/Downloads)? This is needed for USB2.0 support.

    Scott,

    Thanks for your help.  I do. or at least I think I do.  I followed the instructions posted here.

    https://forums.virtualbox.org/viewtopic.php?f=7&t=51991

    Things behaved a per that post.

    Do you have the Windows driver installed such that it shows up under windows as a com port?

    Hi Jack,

    My configuration is: host is OS X and VM is Window 7. I did install the drivers for Windows (I think they came when I installed SmartRF Flash Programmer) and I see "TI CC2540 USB CDC Serial Port (Com 6)" under Window's device manager. However if I understand your setup correctly, your host is Windows and your VM is Ubuntu. Ubuntu is where you are trying to get the USB dongle to be recognized. So I don't think my experience helps you in this case.

    This goes beyond my experience but I wonder if you will need a module installed in your kernel to properly use the USB dongle under Ubuntu.

    Good luck!

    Scott
