I have been running Dan’s python OSPi for a couple of years and have modified it to add a rain sensor and display and control the garage door. It has been running fine on:
Linux ospi 3.12.35+ #730 PREEMPT Fri Dec 19 18:31:24 GMT 2014 armv6l GNU/Linux
for months. I just did a raspbian update which will end up booting kernel 3.18.7+ which has Device Tree enabled by default. This upgrade broke my one-wire temperature sensing on another Pi which required a fix to add a line to /boot/config.txt to define the custom pin I use for the one-wire bus. There was also some docs on getting i2c enabled in the new kernel.
I have not rebooted the OSPi system yet, so it is still running under the old kernel. I’d like to know what to expect when I do reboot it. Will it come straight up, or will it have to be fixed?
Has anyone else come across this potential issue?
Thanks!
Having had some trouble with the new “unified” firmware, I’ve just switched back to Dan’s python OSPi kernel, which is working just fine on the latest version of Raspbian (updated via rpi-update).
uname -a reports: Linux raspberrypi 3.18.10+ #775 PREEMPT Thu Apr 2 18:10:12 BST 2015 armv6l GNU/Linux
So, I think you should be good. Just in case, use something like WinSCP to make a backup to a desktop computer. If it doesn’t work, it is a simple matter to restore it.
