But firm ware upload done is displayed then i had click on connect so why it is display this. Please show me solution
Say “Yes” to linux board.
It is asking about the APM2.6…not your OS
After loading, completely power down the APM and then try to connect.
If it still won’t connect, I would suspect the cable.
Yes, you just loaded the firmware with it but it might be just good enough of a cable for that but not good enough to connect.
This is standard if you are still on the “Load Firmware” page.
Go to another page such as “Flight Data” and connect.
Thanks sir for your reply, actually i am new candidate for ardupilot. Any way thankx it solve my problem
