CC Debugger Problem

Other Parts Discussed in Thread: CC2533, CC-DEBUGGER

Hello

I am working on CC2533.I have designed PCB with optimum connectons. Problem I am facing with CC debugger is that its LED remains RED only. I updated firmware through SMARTRF STUDIO, checked all connections of CC debugger to my circuit. But still LED is RED. 

What should I do now????

Thanks in advance...

    Hi

    Do you have a TI board that you can try connect with the CC-Debugger, for example one of the USB dongles, a SmartRF05EB or SmartRF04EB? Then we can check first if your CC-Debugger is working correctly. The LED should be green when it has successfully detected a device.

    Regards

    Also make sure you have applied power to your CC2533 board. Pin 2 on the debug header is not a power source pin!

    Cheers,

    yeah I have used separate power source and it is giving 3.3v . I have connected pull up resistors to DC pin of cc2533 as given in CC debugger user guide, is it necessary????

    And I dont have any TI board. Is there any other way to check if my CC Debugger is faulty???

    The pull-up on DC is only required for older devices, not the CC2533, however keeping it in should not cause any problems.

    Can you share your schematic, layout and preferably also a picture of your PCB?

    You're not exactly following the reference design layout. You realize the antenna won't work very well without the ground connection?

    I can't see any immediate errors in your debug connections.

    Verify that all VDD pins have correct voltage and also check the voltage on Rbias and DCOUPL.

    Found the problem. DD pin was not properly connected to Debugger header.

    I referred design note DN0007 for antenna design and i found that they have not recommended ground connection to antenna. Do i need to ground it???

    And I am facing difficulty in coding. Can I get any kind of sample codes for packet transmission and reception for cc2533????

    Thank you.. :-)

    Look at figure 1 in the application note. It is also always a good idea to take a look at the reference design(s). The CC2533EM for example.

    Check out the Software section of the CC2533 product page.

    I am trying to compile my code in IAR embedded workbench....

    But as soon as I open IAR it shows me warning

    It says-

    warning: The device description file : C\Program Files\IAR systems\ Embedded Workbench 6.5 \ 8051\ config\ devices\ Texas Instruments\ i0cc2533.ddf
    defined on the Project -> Options -> Debugger page does not exist

    What should I do???

    Still when I  try to generate hex file I get following error...

    Error[e12]: Unable to open file 'C:\Program Files\IAR Systems\Embedded Workbench 6.5\8051\LIB\CLIB\cl-ple-blpd-1e16x01.r51'

    What should I do???
