2016-06-16 Recovered the Raspberry Pi
So when the Raspberry Pi 3 came out in February I bought one, complete with power supply, case, microSD card and small keyboard. I just could not resist it. I installed it, connected it to the network and did not really have a task for it. It is joy.idefix.net.

After a while this changed and I started running dump1090 on it to get an idea of the planes in range from my house. It is connected to the antenna used in the earlier ADS-B receiving experiments and sees high altitude and/or nearby airplanes fine.

Recently I ran some updates and those failed because the root-filesystem was filling up. I did not notice that left some files missing, so I just ran the commands to resize the raspbian root filesystem to fill the SD card - Coderwall and waited for the reboot. This ended up in a nice multicolour screen with nothing running. I looked that up and found Raspberry Pi with boots up with Rainbow screen - Raspberry Pi Stack Exchange so it was time to recover. I mounted the SD card on an x86 linux system and found the kernel.img and other files in /boot were missing. I searched how to mount the raspbian image and found How can I mount a Raspberry Pi Linux distro image? - Raspberry Pi Stack Exchange. I started with using the loopback device, copied the whole /boot directory from that image and did a filesystem check in the SD card. It booted again but showed driver issues. I reran all the updates which reinstalled the raspberrypi-kernel package and after that the driver problems were gone and things worked again.
