Firmware 2.2.3 unstable flight?

Unread post by mhoppes » 04 Jan 2013, 04:22

Has anyone else noticed extremely unstable flight since upgrade to 2.2.3? My
Drone was actually incredibly stable on the previous version, but since the upgrade to 2.2.3 it's all over the place when in the air.....to the point that it crashed into a tree today and I couldn't control it.

I've had my suspicions that it's not as stable, when coming to a stop its a little crazier than before.

But my drone has been slowly detiorating flight wise for a few weeks now as my initial cache of spares ran out and waiting on new shafts and bearings etc so it's been hard to tell for sure.

I've been contemplating going back 2 versions where they say it had the best performance and giving it a try.

Had one near miss downgrading which ARTommy helped me out with or I would have bricked it.

I've been hearing that term all over the place. "Bricked"
Can someone please enlighten me and tell me what that means?

Yeah I understood it to mean useless.
I have heard that term elsewhere on Android Forums. Is it from trying to load different software and somehow damaging it or something?

With devices that have upgradable firmware, whether it's a cell phone or an AR Drone, if something interrupts or corrupts the firmware installation (either a bad release, or most commonly, losing power or otherwise cutting off the install in the middle of it) then this leaves you with a circuit board that is "stuck" because it no longer works enough to communicate with it to start a firmware installation process again, so now the circuits are one solid piece of un-usable material that, from a programming standpoint, is locked solid and useless and you might as well be trying to program a piece of "brick".

In particular though, "brick" is a term that is usually only applied if it becomes impossible to correct whatever is wrong with it short of completely replacing the circuitry with a new board. Otherwise you would use a term like "corrupted" or "locks up" or "crashes" to describe something that is screwed up, but still redeemable by trying the firmware download process again. "Bricked" can also refer to physical circuitry damage, not just programming-wise, such as "I hooked the battery up backwards and bricked the mainboard".

Edit: After writing this, I went and checked wikipedia and found I'm pretty happy with the explanation I just wrote. Check it out if you're interested.
