Segmentation fault on Fedora Linux

[timhughes]

Still having a few difficulties on the Linux build on Fedora.

I have converted the .deb package to a rpm like this:

mkdir ./labrador
dpkg-deb -R labradeb.deb ./labrador
fpm -s dir -t rpm  -v 0.9.1 -n labrador -p labrador-VERSION-ARCH.rpm -d libusb -C ./labrador etc usr

/var/log/messages

Looking through the trace i think I have managed to work it out

I installed dfu-programmer and then flashed the firmware manually

dfu-programmer atxmega32a4u erase
dfu-programmer atxmega32a4u flash /usr/share/espotek/labrador/firmware/labrafirm_0002_02.hex

Then I needed to power it off and on again before running /usr/share/espotek/labrador/Labrador

Yup I was just writing to suggest that is what was needed. Hope it all works better for you. Glad to hear a manual update worked. Chris Esposito has been working had to get that to work as part of the install, but that would not have happened with your ,deb conversion.
