Firmware Update Problem on Dynamixel Pro M54-60-S250-R
2018-12-07 17:45:26 genrob

We have updated successfully 2 of 3 servos from firmware version 25 to 27. For the last servo the firmware update was not working. Now also the R+ Manager does not find the servo any more. Firmware recovery is also not working as documented.

Please advice what else can be done or, if we need to get a replacement/repair. All 3 dynamixels are brand new. 

Thank you.

We apologize for your inconvenience with our product.

It sounds like the communication IC is troublesome, however, in order for me to decide whether the product needs to be repaired or not, I need to collect little bit more information.

  1. Which interface controller do you use? (U2D2 or USB2Dynamixel?)
  2. Which Power source and voltage level do you use for Dynamixel?
  3. Do you see the LED blinking once when power is connected to Dynamixel?
  4. Did you connect only one Dynamixel when recovering / upgrading firmware?
Thank you for your patience.

Sorry that we got in touch so late, we were on our way, we used the USB2Dynamixel, the firmware recovery was done with only one servo, without success.
Power supply is a 24V/10A power supply. When switching on the LED lights up for about 1 second.

Hi Thomas,

That doesn't sound normal.

Could you go over the self checklist?

If you end up getting a CODE number, please request RMA service.

We apologize for your inconvenience.

Thank you.
