Did I kill it? AVRDude, SmartieParts, Death! -- RESOLVED

[drivintin]

Ok guys, I think it is dead, but would love some ideas.

FlySky v2 board. SmartieParts v2.1

I have had this around 6-8months. Honestly it has been in the garage unused for a couple of months. Anyways I break it out and do an upgrade, then reupload the data and realize the formatting has changed some, so flash it again and let it just format. Well I keep getting the verification failure, try like 5 different roms, and get one to take. Then I change again and it never comes back up. Of course I read now that you shouldn't flash that often, that fast. It reads the fuses ok, then I try to modify them and bang, it never comes back. Now I just get:

Code: Select all

         this check.


avrdude done.  Thank you.

AVRDUDE done - exit code 1

So now I can't reset the fuses, or upload firmware or anything. So side note, incase it makes a difference. The SmartieParts board has never powered my radio enough to do the flash. I have always had to have a battery in, and turned it on to get it to flash. So now the screen is blank and never comes back up. I used this pic , and I have power at all the points (with battery).

Any ideas? I am thinking of ordering an Oscillator and see if I can flash with that. Only thing I can think of.

If using the Smartieparts board, and it has been in the garage for some time, it might be worth removing the SP board, cleaning all the connection pads and then replaceing the SP board.

Sorry, looking back at the post, I didn't make things very clear.

The board and contact points were cleaned.

The fuses were reset based off a post I found, and sadly I didn't keep those numbers, so thinking maybe they were wrong. Now basically waiting for an oscillator to come in the mail. Anyone know the range on the oscillator that you can use? I ordered the 1mhz, and sadly the lowest I could find around the house was 14mhz, was thinking it needed to be 8mhz or below.

Thanks guys

TADA!

Haha, I can't believe it, but I was actually able to bring it back to life with the oscillator!

I sodered the clock lead in (which was EXTREMELY small) with my horrible sodering skills. Then I actually sodered the power leads to the smartieparts board since it had nice fat places I could soder.

The first reset failed and said it couldn't find the device again. Tried another machine through a powered hub and the fuse reset still failed. Then I did a firmware flash with the force and -B 100 to slow it down. It actually wrote the firmware and verfied correctly much to my surprise. But the screen didn't come on, so I was scared more was wrong with the unit. So I tried the fuse reset one more time:

Obviously I was thrilled!

I will say I actually wrote the firmware with the oscillator still attached. Mostly because I was under the impression that it was either wired wrong, or else it wasn't working at all.

I want to really thank the guys who found this stuff out, and made the fuse brick pdf. The $5 spent on getting the oscillator saved me from having to buy another radio!
