Control transfer failed: -7 - need a little bit of help

anon5189335 · 2016-02-03 18:14:16 UTC

Hello

When I connected Axoloti to my Macbook 2012, Yosemite, this afternoon, it was suddenly static green anf the red led was blinking and the board didnt connect. I am using latest ofiicial release 1.0.6 and runtime 1.0.6.

I tried connecting Axoloti and holding S1 in and do the rescue. It finished allright, but it still has static green and blinking red LEDs. Unfortunatly I didnt get to see the log before the firmware rescue, cause the app crashed before I had the chance.

After the firmware rescue. I get this message:

I tried different cables, different Macs, rebooting them and nothing seems to help. I also tried downloading and installing the runtime again, but with no luck.

I am out of ideas now. Am I missing some step in the rescue proces?

Thanks

After reboot of computer again, Axoloti is back to not connecting at all and it is still blinking red. I get this error:

Board revision 1.0?
Is IC3 behind the line out jack extremely hot?

workaround https://sebiik.github.io/community.axoloti.com.backup/t/might-have-fried-the-output-of-axo/573/15

anon5189335 · 2016-02-03 19:38:51 UTC

Got it as one of the first last year in May, I think it was. Cant locate the revision number, but I am pretty sure it is revision 1,0.

It doesnt get any more hot that my other board from same batch. Just tested that. I received both at the same time.

What does this mean(from the log):
java.lang.Exception: cpuserial has wrong length

johannes · 2016-02-03 20:02:19 UTC

That means the communication protocol was not in sync.

Perhaps a startup-patch in flash memory that fails during boot? Try push/hold switch S2 during powerup of the board (till the end of the alternating green/red blinking sequence), that skips loading any patches from sdcard or flash.
Rescue ("dfu") flash does not erase the flash startup patch area.

anon5189335 · 2016-02-03 20:15:11 UTC

Ohh just check IC3 again.. Now it is hot. I think i didnt touch it right the first time. Now it was burn your finger hot... Bummer...

Ok, so I need to go through the other thread about the workaround. And read it over a few times. But from what I see from first read, I wouldnt feel comfortable doing that at all. I have almost no experience with the hardware side of it.

Anyway, back to reading

Thanks

anon5189335 · 2016-02-03 20:24:19 UTC

Just for clarification:

Can this happen if you disconnect/connect the audio stereo output while the board is connected via USB?

anon5189335 · 2016-02-03 21:51:52 UTC

Ok, so now my second Axolotis output is dead... After first board died earlier today I was extremely careful with my other board and connected it to play a bit. with same cables as I have used for the last many month.... But no sound from that one either.

Guess that is another topic. I am out for today. 2 unusable boards on same day. Too much.

Kalle · 2016-02-04 08:00:23 UTC

So Johannes what does IC3 control and is this something other users should fear ?! was jakob just unlucky or?!

what will happen now will he get a refund board since its not even a year old?!..

im a bit concerned over my board now ...

anon5189335 · 2016-02-04 08:27:21 UTC

Yeah, actually I was also thinking about either have a warranty fix og replacement boards. Cause it is definatly within warranty. I guess I need to contact the developer in person to find out this, cause community has no guide lines on the subject.

But since within warranty I am not that concerned about it any more. Now it is just a matter of how long time that process will take

johannes · 2016-02-11 15:17:56 UTC

I'm unsure how crowdfunding perks and board-level products fit in EU warranty regulations.
It is hard to make warranties on a product so open and hack-able.

That said, I'll try to be as reasonable as possible.

Generally I will ship replacements in the following situations:
- dead on arrival (notified within a week after arrival)
- manufacturing defects (assembly or solder faults...) within one year

I will not cover damage caused by handling or improper use, and damage caused to external equipment.

This particular defect could have been caused by the micro-usb cable violating the usb specification (shield left unconnected), or it could have been caused by the powersupply of a laptop or other connected equipment leaking current into ground (they shouldn't but it's not unseen in reality). I have not been able to provoke the latter with my own equipment.

This is how I propose to handle this case:

Send me a private message to obtain an RMA number
Ship me your defective board (on your own expense)
Allow me to verify the reported defect.
Return shipping is also on your expense, I will invoice this before shipping out.
I will ship you a working Axoloti Core (refurb or repair) with protection diodes added.

Alternatively, there is a workaround that bypasses the line output driver, that requires a bit of soldering, documented here.

Owners of a revision 1.0 Axoloti Core that want to prevent the same defect from happening to their board in the future are invited to add protection diodes as documented here.
I'm not offering a "preventive repair" or doing a total recall. The number of failures is very low.

Axoloti Core revision 1.1 (shipping since Dec 3, 2015) added protection diodes, and I have not heard of a single similar failure of revision 1.1. The board revision is printed in dark green on the side edge.
