I’m having trouble uploading code the ardupilot getting the sync error each time i try to upload. Im not sure how relevant this is but i have successfully the MUX can get the LED’s to switch on/off.
I have tried using two different USB->TTL adapters on both a system running XP SP3 and one running windows 7.
The one listed here
was provided with remzibi’s OSD and has been successfully used it with the OSD and a TTL GPS.
I also tried to use this
one. I couldn’t get it to work but have not yet tested it before so it could be the adapter that is faulty.
I believe i have everything connected ok, the ardupilot is powered by the +- pins of a ESC and the USB-TTL adapter is connected as follows:
USB-TTL adapter: Ardupilot
I have read through the debugging tips without any further success.
I have definitely selected the right COM port and selected arduino . I cannot seem to access the RTS setting in your PC's port settings, perhaps it has changed?.
Any advice would be much appreciated.
