Re: [avrdude-dev] [bug #40615] Doesn't work with JTAGICE3 firmware 3.18

[Andy Somerville]

I went through the long process of trying to get it to work and got fairly
far, but gave up since I had another option before getting it to work
completely.

I left off with avrdude connecting, but with the JTAGICE3 not responding to
commands as if the protocol had changed or something.

I forked the project on github and you can see my patches in the link below.

Let me know if it helps, and if you get any further than I did.

Hey all,

I've recently begun the slog that is setting up a workflow for avr32 in
Linux. In doing so I've come across 2 problems in avrdude trying to get a
AVR JTAGICE3 programmer working.

  1. avrdude wasn't recognizing the device because the latest firmware
upgrade (3.8) changes the productId

  2. The kernel was holding on to the device and was showing:

avrdude: usbdev_open(): error setting configuration 1: could not set config
1: Device or resource busy

     when I'd attempt to connect.


As a result I fixed both issues locally, but wanted to give them back.


I've attached the patch and also provided a link to a git clone of the svn
repo with the changes:
