Hi there, I need technical support for old CM-5 robotis controller, no charge, no response, when I power on, only power red led lit, when I press any other button, nothing happens. When I press Mode/Reset button, power led goes to Off, when I release Mode/Reset button, power led lit again.
I try to connect via serial port, but not communicate, please advise how to restore my CM-5?
Can I update on board ATMega128 MCU?
please advice
thanks in advance
best regards
Instructions on how to complete a firmware update or restoration are available on our online manual.
I’d also recommend that you check if the fuse is still good, although if the battery isn’t charging there may not be much that can be done to repair the controller. The CM-5 has been discontinued for some time, and replacement components may not be available.
Thanks for replay, I replace with new IC serial comm IC MAX202. I think the problem is in ATMega128 mcu on board. I will try to change main on board MCU with new one. Can you please advice where can I found *.hex file for MCU?
The hex files for the CM-5’s onboard firmware are not publicly available, unfortunately.
You may still be able to complete the firmware reflashing procedure through the manager, but user replacement of the MCU is not officially supported by ROBOTIS.
