    When you upload you are getting a successful upload message correct?

    Did you buy these servos new? Or were they used?

    These servos are new. It says, ' Done downloading' after after I click the download button.

    I made my servos to work. But, the one on which I was experimenting is not working. A possible reason could be that, I have connected the signal to ground and ground to signal. What happens if those two are interchanged?

    I think if you do that, the signal pin sees -5V... not sure how well protected the servos are to this particular situation :s

    If you reverse the polarity of a Dynamixel servo, you will burn the buffer/interface chip.

    Re: Robotis OpenCM9.04 need help.

    Is there any method by which, I can check whether I have burnt my buffer/interface chip? If it has got burnt, what is the procedure to rectify it?

    Re: Robotis OpenCM9.04 need help.

    You can check the buffer chip by attempting a "firmware recovery" using the Dynamixel Wizard. If that doesn't work, the buffer is gone.
    If you don't have a USB2Dynamixel or USB2Ax, then it's harder to confirm for sure. If you have code that works for all the other servos, but not this servo, then it's very likely it's damaged, though. And I would recommend getting a USB2Dynamixel or USB2Ax :-)

    The procedure is to contact the vendor of the servos (Kyle at Trossen, if that's where you got them) for technical support, and they will let you fill out a RMA spreadsheet, and then you send the servos to Robotis in California. They can change the PCB in the servo.
    If this is covered under warranty, you pay shipping there.
    If this is considered user error, you pay shipping, PCB/labor, and shipping back. The PCB/labor isn't terribly expensive -- much cheaper than a new servo :-)

    If you're not in the US or Korea, the process may be more complicated or slow or costly -- I don't know which countries have Robotis reps other than those.
