Hello.

I got the image emlid-raspberrypi2-raspbian-rt-20150401.img from the download section and put it on a sd-card.

when starting the RPi2 i get a kernel panic:

List of partitions
b300                7782400 mmcblk0 driver: mmcblk
  b301                   57344 mmcblk0p1 0009bf4f-01
  b302               3138560 mmcblk0p2 0009bf4f-02
No filesystem could mount root, tried: ext4
Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(179,2)
CPU: 3 PID: 1 Comm: swapper/0 Not tainted 3.18.9-rt5-v7+ #1
...

repairing the ext4 partitions seems to work with gparted.
when starting with the repaired partition still kernel panic:

EXT4-fs (mmcblk0p2): mountedfilesystem with ordered data mode. Opts: (null)
VFS: Mounted root (ext4 filesystem) on device 179:2.
devtmpfs: mounted

Kernel panic - not syncing: No working init found. Try passing init= option to kernel. See Linux Documentation… etc.
CPU: 1 PID: 1 Comm: swapper/0 Not tainted 3.18.9-rt5-v7+ #1

what to do?
how can i make it boot?

thanks for any hints!
