APM 2.5 Usb port problem

Hi everyone.

I use the APM 2.5 for my projects. At the beginning I was using the arduplane and I loaded the firmware via usb. Everything was good and I was controlling my Bixler type plane. But after that, someting happened and I guess the port`s zener diode or something burnst out. So I havent use usb port anymore and now I am just using telemetry to communicate with APM.

Now I bought a hexa-copter and I have to renew the firmware on APM as Arducopter V3.0.1. But as I said above I cant connect to apm via usb and so I cant re-configure or reload any copter types. The telemetry features is very limited as you know. The system does not allow me any change via telemetry. So I have to solve the usb problem. Could you share your suggestions with me ? 

Thank you

  • Hello Mustafa,

    Does your USB actually power the APM successfully?

    If USB power is successful, is it only a communication issue?

    These are two very different problems. If the APM zener were shorted, the APM would not work at all.

    The USB connector has a fuse on the APM side. That fuse can open and prevent USB power/connection.

  • I'd love to know this too - My USB actually works to telemetry, but the APM 2.5 crashes when I try to do a firmware update. Everything works fine apart from that, so would like to upgrade to 3.0.1 via an alternative port. I think there is a serial port possibility, but I haven't looking into it yet.
