DFU 1.1 Support?

[Yohan PAINCHAUD]

Hello all,

First of all, I would like to thanks all the contributors of this library, this is actually the only one available in GPL.

I would like to use this library with a new USB device that implements the DFU 1.1.

Is this library supporting the DFU specification 1.1 ?

I read in the mailing-list that the version 0.5 may support it, but not yet tested?  I saw that the DFU 1.1 has few attributes modified, as for example the Run-Time DFU Functional Descriptor, but in the 0.5 version, only a modification concerning the bitWillDetach flag has been done. Maybe the others changes have been implemented in an older version?

 

Thanks a lot

Yohan

Glad to be of service.

By now we should have al pieces together, but we lack any device to
test it. Would be great if you can do that for us. It would be also
nice to get a lsusb -v output for the DFU 1.1 device.

Correct.

Also correct. We may lack something we haven't thought about for
now only testing will reveal this. Would be great if you could
help us out here.

Yes, some 1.1 parts were already supported by earlier dfu-util
versions. Some firmware implementations use a mix of 1.0 and 1.1.
dfu-util retrieves the run-time functional descriptor if it can. But
this is not new in 1.1, is it?

I believe the SPEC-differences.txt file in our source tree describes
all the differences between 1.0 and 1.1.

Oh and by the way, having the bitWillDetach flag set is not mandatory
for a DFU 1.1 device, and we already supported the 1.1 devices which
had this flag cleared also before 0.5 as far as I know. Just that I
don't know of any 1.1 devices :)

Thanks a lot for your reply.
We will be able to test the library during December ...
I will post a new message on this mailing-list with the status of our tests.

Regards
Yohan
