Migration from Rpi1 -> Rpi2

[Nachteule]

Ah ok.

Maybe wrong root fs (/dev/sda1) is still in initfamfs.gz (not sure if this is stored in initramfs or not, never checked this). You could try to disable initramfs by commenting out it in /boot/config.txt by something like this

Code:

#initramfs initramfs.gz  0x1500000

or simply remove or rename /boot/initramfs.gz and try again booting

and you can enable debug and disable splash by

change splash to nosplash and adding debug to cmdline in /boot/cmdline.txt
