Re: Linux kernel is now 4.4

The earlier sources can be found at "https://github.com/raspberrypi/linux/commits/rpi-4.4.y" by searching down through the commits until, for example, "Linux 4.4.44" is found and then clicking on it.

For that reason the program has to be compiled against the version-specific kernel build system of the Raspian OS on which the program will be run - a bit of a pain but not a show stopper. However, in attempting to retrieve the sources for Linux ...

After a lot of tial and error (mostly error!) I got NTP to respond correctly to the PPS clock. The o...

Re: Raw sensor access / CSI-2 receiver peripheral

At the moment the only i2c device on my RPi 2 is /dev/i2c-1 and so far no luck in getting a /dev/i2c-0 device working. Is it possible to get raw sensor access working on ic2-1 instead? Or do I have to first get ic2-0 going?
