Firmware update: Segmentation fault: 11?

[synimak]

I am trying to update a PyB v1.1. I have dfu-util working but I keep getting "Segmentation fault: 11". Any ideas?
I'm running a 2013 macbook pro and don't have another devices connected.

Code: Select all

$ /opt/local/bin/dfu-util --a 0 -D pybv10-20161127-v1.8.6-100-g21e1703.dfu -d 0483
Segmentation fault: 11

I just tried that exact command on my linux machine and it seems to work for me. I'm using the latest dfu-util built from source.

The only things that looked odd to me were that I'd use -a instead of --a and I'd try -D 0483:df11 rather than just -D 0483

@dhylands A couple of things look odd to me. The OP says he is trying to update a V1.1 board but the firmware filename is one for a V1.0 board. And I'm puzzled by the vendor/product ID: my V1.1 board lists (lsusb) as f055:9800. Where does 0483:df11 come from?

I have 0483:df11 too

I didn't notice the version mismatch. Although I don't think that should be relevant, since the seg fault is happening on the host right at the start. The version mismatch would probably cause the board to not boot though.

0483:df11 is the VID:PID that shows up when the board is in DFU mode. f055:9800 is what shows up when its running MicroPython.

Thanks for all your help guys. You are all absolute legends!

Sorry there has been a few things I have totally missed. It is chaos at work at the moment. A quick bit of background...
I am a Special Effects(SFX) Technician and Stunt Rigger/Performer. I'm currently working with SFX on Pacific Rim 2 in Australia. I've been using the PyBoards since they came out and absolutely love them! So far I've used a bunch of them on, Pirates of the Caribbean: Dead Men Tell No Tales, Alien: Covenant, Thor: Ragnarok, and now Pacific Rim2. That's all I can say at the moment but when the films come out I'll be able to share some videos and pictures of how they've been used. Also I have no offical training in programming so its all a bit of a stumble along. Learning as I go.


So I have a bunch of v1.0 and v1.1 boards and I've mixed them up without checking properly.

I am updating a v1.0 board not v1.1.

I changed the "--a" to "--alt" (as per the instructions, something else I missed) and that has made a difference.

BUT now I end up with "–device: No such file or directory"

Code: Select all

$ /opt/local/bin/dfu-util --alt 0 -D –device 0483:df11 pybv10-20161128-v1.8.6-104-g0d75b0d.dfu -d 0483
dfu-util 0.7

Using "-D 0483:df11" rather than just "-D 0483" doesn't make a difference.

Once again thanks for all your help!

Fixed it.

Works using:

Code: Select all

/opt/local/bin/dfu-util -a 0 -D /opt/local/bin/pybv10-20161128-v1.8.6-104-g0d75b0d.dfu -d 0483

Thanks Again Guys!

Generally speaking, if the option is a single letter, then it has a single dash (-a, -d) and if its a word then it uses a double dash (--alt, --device).

Of course, there are always programs which have their own conventions (mostly for historical reasons) and don't follow this convention, but that's generally a good guide.
