So here's what I did:
Downloaded latest image file and extracted .img file
Formatted SD card
Wrote .img to SD card with Win32DiskImager and put SD card in RPi

Connected RPi to network and used PuTTY to connect to SSH

Catapult, the current nightly is unfortunately broken due to an outdated package in the image.

Code: Select all

22:25 < jbaiter> jfyi, the last image probably won't boot
22:25 < jbaiter> i just noticed that I introduced a feature from tornado 4.0 in one of the last commits
22:25 < jbaiter> while the spreadpi image is still on 3.2
22:26 < jbaiter> quick workaround: sudo apt-get remove python-tornado; sudo pip install tornado
22:26 < jbaiter> on the pi
22:26 < jbaiter> it should start again after that
If you do these two commands and reboot the Pi, spreads should start up automatically.
virtualenv is no longer needed!

I just pushed a fix to the SpreadPi buildscript to GitHub and a new nightly build should be available tomorrow morning.

I appreciate all the work done through this forum but am having trouble find spreadpi.img download.
Would anyone be able to help with locating this image?

Thank you!!
