Anyone who is into Arduino programming?

Dear Prateek,

Your 3.3v regulator is blown. It is a tiny SMD device that needs to be changed.

Cheers

Bind RX again

@asupan - Are you sure about that? i can provide a pic if you want to visually inspect it.
@roshan - The rx is not even connected! It isn't a rx/tx problem.

You can check whether regulator is blown or not, altho I dont think thats the case.

Prateek,

I can't be sure until it is checked. It is possibility that you need to check out.
It is purely based on my experience where there was the similar issue of not connecting to mission planner.
Cheers

I had came across same issue change the USB cable!! And then press the restart switch on the apm, uninstall and reinstall mission planner!! There May be a chance that the Drivers may have got corrupted!! So try this

According to my research I think that the bootloader is corrupted. I will try to reinstall it, if it still doesn't work then I may just let it go

Just tried smth new: Burned the bootloader on the 2560 using an UNO.
Now I can upload firmware but the CLI still doesn't show up.

It just says: Init Arducopter V2.7 ..... load_all took 532us.

I uploaded a lot of test programs like GPS test, Baro test, Compass test, Blink and they all work, but the ArduCopter program cannot be uploaded as its size is more than what the 2560 chip can take.

Any help?
