RE: Migration from Rpi1 -> Rpi2
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 0x1500000or 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 |

RE: Migration from Rpi1 -> Rpi2
One thing I did think of was that kodi overrides the initramfs setting in boot/config internally (remember setting it to 'always' in kodi menus).
Do you know where I can change this as I expect it to interfere when trying to boot without initramfs.  update... I tried it anyway and now it does not boot. Just get a flashing underscore in the top left corner.  I have removed the SD card and am wiping it completely and then re-install the rpi1 image and try again. May take some time though....  Here is cmdline.txt... Terminal telnet zswap.enabled=1 zswap.compressor=lz4 console=tty1 root=/dev/mmcblk0p2 rootflags=subvol=root/@,autodefrag,compress=lz4 rootfstype=btrfs rootwait logo.nologo quiet noswap loglevel=0 partswap startevent=mountall selinux=0 splash nohdparm net.ifnames=0 biosdevname=0 --startup-event mountall Seems that removing initramfs from /boot stops it even getting to splash screen. Going back to initram I get a message to press shift before the splash appears. Even doing this it hangs at 'loading' screen. Maybe it's better to start from scratch now? and config.txt... Terminal #initramfs initramfs.gz 0x1500000 gpu_mem_1024=256 gpu_mem_512=144 gpu_mem_256=100 initial_turbo=3 hdmi_ignore_cec_init=1 hdmi_force_hotplug=1 disable_overscan=1 disable_splash=1 dtoverlay=hifiberry-dac dtparam=i2c_arm=on dtoverlay=i2c-rtc,ds3231 decode_MPG2=0x73c4f0f6 #dtoverlay=lirc-rpi arm_freq=700 core_freq=250 sdram_freq=400 over_voltage=0 |

Hopefully you do no have Alzheimer  , we already discussed this hereQuote:update... I tried it anyway and now it does not boot. Just get a flashing underscore in the top left corner. That's what I was already talking about, all you was seeing came from initramfs. So, I suppose your root fs (/dev/mmcblk0p2) is broken Quote:I have removed the SD card and am wiping it completely and then re-install the rpi1 image and try again. May take some time though.... Make sure that your saved image is correct. Btw, you can check log of image generation. See file /tmp/xbiancopy.log (here one of mine RPi1 from building image yesterday) xbiancopy.log (Click to View) Quote:Here is cmdline.txt... Looks ok Quote:Seems that removing initramfs from /boot stops it even getting to splash screen. Going back to initram I get a message to press shift before the splash appears. Even doing this it hangs at 'loading' screen. Maybe it's better to start from scratch now? See above, no initramfs, nothing on screen Quote:and config.txt... Looks ok You can force entering into rescue mode by adding rescue as additional parameter to cmdline in /boot/cmdline.txt. You need do attach an USB keyboard to your RPi Please note: For rescue mode initramfs has to be enabled |

RE: Migration from Rpi1 -> Rpi2
I hope no Alzheimer too, a hangover though I do have
Added rescue but no change. Tried holding down both left shift and right shift (even space bar), but still goes as far as loading and halts once the bargraph has completed slowly. FWIW heres the new cmdline.txt..... Terminal telnet zswap.enabled=1 zswap.compressor=lz4 console=tty1 root=/dev/mmcblk0p2 rootflags=subvol=root/@,autodefrag,compress=lz4 rootfstype=btrfs rootwait logo.nologo quiet noswap loglevel=0 partswap startevent=mountall selinux=0 splash nohdparm net.ifnames=0 biosdevname=0 --startup-event mountall rescue |

I was reading long time ago that the shift key only works with wired keyboards |

RE: Migration from Rpi1 -> Rpi2
Weird it sure is - today trying to do this in parallel with a mysensors gateway/node problem and cleaning the house..... So far none of them are winning..... Maybe rescue mode not starting is a clue?
I have wired usb keyboard attached. And USB mouse too. Network and hdmi cable. That's all (apart from power)..... I could try rescue_early (been reading the wiki!).... but probably get the same result. Initramfs is enabled in config.txt again too, so not that. Aha! I now have recovery console. Seems that rescue only works if splash is set to nosplash..... Who knew? So, before I dig an even bigger hole, can you kindly let me know what to do now.... ??? |

Maybe rescue mode not starting is a clue? Wow, that's great Quote:Seems that rescue only works if splash is set to nosplash..... Who knew? No, at least not here. But disabling splash is better for investigating issues ... Quote:So, before I dig an even bigger hole, can you kindly let me know what to do now.... ??? 1) Checking, if your root fs is ok - it should be mounted to /rootfs automatically 2) type exit to continue normal boot process and look if there are error messages |

RE: Migration from Rpi1 -> Rpi2
Now we see the problem....
Switch_root: Failed to execute /sbin/init: No such file or directory Not sure if it is good or bad news though.....

Another chapter for "afterwards you are always wiser" It would be good idea to check backed up images from time to time (look into file /tmp/xbiancopy.log): Since image backup of my dev RPi3 failed once (BTRFS complained filesystem error, so root fs was empty in image), I was generating this log file and I'm checking this file sporadically

RE: Migration from Rpi1 -> Rpi2
@Nachteule,
Sorry for the delay, been in hospital....but home now (with a new hip!).... I got it all working except the lcd display which would not work no matter what I tried. But last night I took another look and it is all working as before with pi2. Now much faster response to menu and streaming. I am happy with this.
