No power during flashing and "Verification failed"

Post by Evils » Thu Nov 26, 2015 11:23 am

Hi everyone,

it seems like I bricked my Turnigy 9x.

A while ago I did the telemetry mod and it seems like I screwed up. At one point during the mod I did a mistake when cutting the trace on the backplate which led to a burned trace on the third pin. I replaced that trace and redid the correct cutting and though everything would be fine.

Since then I tried to reflash my Turnigy 9x with my USBASP and with my Arduino, but I always get the following error at the end:

Code: Select all

avrdude: verifying ...
avrdude: verification error, first mismatch at byte 0x0100
         0xff != 0x3a
avrdude: verification error; content mismatch

Now I know that there's a certain bug with avrdude on the mac, but this is not it. I tried with Linux and Windows -> same behaviour.

What scares me off now is the fact that while flashing my remote doesn't power up like it used to be.
Normally when I attached my 10 pin cable and the 5V came through, my remote powered up. This isn't the case anymore.

When attaching the battery to the remote, the remote powers up but the screen stays blank.

I don't see anything else burned or faulty on my remote that could cause this!

Any help is highly appreciated!

Thanks

hmm, I don't see how cutting a track would damage something, Unless you had the radio ON when you did it? :o
Please post some pictures of what you did. We need to know exactly what you did.

What firmware are you trying to flash?
try typing -B 100 in the extra arguments field

Okay let's see.

The problem is that I was trying to get the telemetry mod working where you attach the two 220 Ohm resistors on to the ATMega64 chip (and remove the two smd resistors instead) and you connect RX and TX to the back plate so the telemetry data from the module will be displayed.

After doing this and not properly cutting the traces on the back plate I had a little short circuit which burned a trace on the back plate (see picture attached).

I fixed all that (cutted the trace properly, redid the connection that burned down) and was able to reflash the Turnigy 9x back then. I got an error message about two of the back switched though, I think it was ID2 and AIL, that they were on even though they weren't. (I figured that's part of the Telemetry mod, but if not, I might have screwed up(if so, tell me).

The -B 100 option doesn't fix my problem unfortunately. I tried that before with different values in the -B range to no success...

Thanks

The track that burnt seems to be the switched Battery voltage that powers the RF module. Are you sure you didn't solder the wire to the wrong pin? or maybe there was a short between those pins? the track that burnt has nothing to do with the telemetry mod as far as I know. It looks like that you somehow shorted the battery voltage to something else. Please post also a picture of your mainboard, we would like to see what you have done there..
If you connected the telemetry wires to battery voltage you could have fried the processor. But it is too early to conclude that..

Try to read the firmware or the eeprom to a file instead of trying to flash. See if it works. You still didn't say which firmware are you trying to program.

Did you cut the tracks on the pins the blue and yellow wires connect to? On BOTH sides of the board for the yellow wire.
The telemetry signals on those wires are also signals used while programming. You might try removing the blue and yellow wires and checking if you can read/flash the processor then.

Attached are two pictures of the current state of the PCB's.

Here's some more info:

I'm trying to flash the latest ER9X from the "next" branch as I'm using the multimodule from RCGroups.

I'm also able to read and then verify the flash memory on the RC.

What most likely happened is that the yellow cable touched the pin underneath which ended up in the short circuit I mentioned...

Let me know if these pictures work, otherwise I'll make some more.

I can't see any pictures ;)

If the yellow wire touched the pin underneath on the backplate, then it had battery voltage on it and straight into the processor.. What battery are you using?

I've updated the pictures, my bad.

I'm using a 3Cell 11.1V battery.

Wouldn't that mean that the processor would be gone completely? Because like I said, it's been working before I tried to flash it and right after that stuff happened.

It appears you have hardware issues as well ( burned up a trace myself at one time ), but this could very well be the cause of your mismatch at 0x0100

Try what Mike suggested, disconnect the wires from the backplate and try flashing the radio..

Re: No power during flashing and "Verification failed"

Post by Evils » Thu Nov 26, 2015 1:38 pm

It worked!!!

I just updated through homebrew to the latest HEAD version and it worked perfectly. The remote works again (I assume). I got a "BAD EEPROM" alarm at first.

Now before we end this, I have a few questions regarding this:

1.) normally the remote powered up when I attached the programmer, why isn't that the case anymore?!
2.) I still get the error message that THR, ID2 and AIL are on, no matter what their state is. Is that normal?! I assumed that's due to the Telemetry mod!

Thanks a lot guys for the help here

You are a very very lucky man.. :)

You would have to flash the telemetry version of er9x Otherwise AIL and THR won't be recognized as they are now on different pins of the processor.
That doesn't explain your ID2 switch problem though.. It needs investigating. Go to Radio Setup/DiagSwtch, and move your switches. when they are off the number in front will be "0". when they are ON, the number will be "1".
What do AIL, THR and ID1 and ID2 show when you move them?

AIL and THR don't move at all when watching the values in the DiagSwtch menu.

I compiled my version of ER9x with "make EXT=FRSKY-NOHT" (NOHT cause otherwise it claimed to use 101.xx% of my memory. That should be the right version or not?!

Go to www.er9x.com, download the file "er9x for M64-FrSky (right click and select 'save as')" and flash it.

Use:
make EXT=FRSKY TEMPLATES=NO
or, go here: viewtopic.php?f=5&t=4598#p64969, and download "er9x-r819Prov.zip", extract er9x-frsky.hex and flash that.

So, after flashing the version from er9x.com, AIL works, but THR still doesn't.

Is that supposed to be the case?

Edit: On another note, I still don't get why I don't have any power during flashing as I was used to be.

No, both should work. The THR switch is on the red wire. Check at the processor pin there isn't a solder short to the pin to the other side of the black wire.

Apparently it wasn't the pins that connected but the lower connections...

Everything seems to work now! Thanks guys

With this whole soldering, I learned a hell lot, but I feel like it's with a house "You build the first one for your enemy and the second for yourself."

Btw. I intend to put hot glue over the PINs where I soldered as they feel weak, any reason I should not do that?

No problem, and a good idea. I use fine, single strand wire (kynar wire) for connecting to processor pins. It is easier to solder, no chance of stray strands, and puts much less strain on the soldered joint.
