Having some trouble getting OSMC going on an RPi v1.2 Have tried several confirmed working microSD cards in another Pi, and various OSMC images.
Raspbian etc. boot just fine, OSMC gets stuck on rainbow screen, with the green LED flashing 4 times slowly then 4 quick flashes. Any ideas?
Definitely selecting RPi2 image in installer, tried RPi1 just in case but as expected no boot.
Can anyone help please?
If you’re sure it’s a Pi2, then the correct image will have rbp2 in the name. (I did once try a rbp1 image on a Pi3 and got the rainbow screen.)
it might be a power-related issue or a bad SD card. Ensure that the power supply is sufficient and/or try a different SD card.
Definitely Raspberry Pi 2 Model B v1.2
cat /proc/cpuinfo
Gave me a rev number a22042, which led me to Raspberry Pi Documentation - Raspberry Pi hardware
2B (with BCM2837) 1.2 1 GB Embest
Tried several power supplies and microSDs, I’ll hijack the working Pi’s PSU when it’s idle - OSMC being enjoyed by my partner at the mo!
Could it be anything to do with the v1.2 Pi2 using the Pi3’s CPU? Though I’m assuming this isn’t an issue or there’d be more threads here on the problem!
Yes,
It’s possible that the firmware in the installer images is too old for this to boot properly.
The installer needs a kernel + firmware sync soon to resolve an issue with a small subset of SD cards as well:

__Details__:
* Hardware:
* * Raspberry Pi 3
* * Class 10 microSDHC with 8G (g… enuine Samsung)
* * HDMI Connected screen
* * 2.5 Amps USB PSU
* * Laptop running Gentoo (4.4.6 kernel) and a USB-SD dongle
* Reproducible: Always
* Steps:
* * Download official OSMC_TGT_rbp2_20161224.img
* * `dd if=OSMC_TGT_rbp2_20161224.img of=/dev/sdc`
* * Insert SD into RPI3
* * Insert USB jack into RPI3
* * Screen now reads `Formating device`
* * No activity on the LEDs, No change after 12h of runtime
* * Unplug USB
* * Insert SD into Laptop again, See newly created EXT4.
* * Mount EXT4 - Empty.
__Attempt 2__:
* Manually extract filesystem.tar.xz onto said mounted EXT4
* Attempt to Boot
* Same behavior, Stuck again.
__Attempt 3__:
* Manually extract filesystem.tar.xz onto said mounted EXT4
* Remove filesystem.tar.xz from primary FAT32
* Attempt to Boot
* Blank screen
As this has been reported multiple times on the forums, this should be considered an actual bug.
I've tried to extract the zImage to see what the setup script is actually attempting to do but I had no luck in doing so.
From a naive interpretation of what I experience I would guess that it's a timing issue where the SD card is not formatted quickly enough and thus the next steps are being soft-failed and skipped rather than waited for.
Happy to serve as a lab-bunny for debugging. I'm on IRC under the same nick.
PS:
I cant find where `logger` writes logs to, any clues?
The code looks fine, couldn't find any obvious issues that would explain my behavior.
So now looks like a good time for us to update and make some testing available.

Interesting page. Not seen it before.
My Pi3 is revision a02082 3B 1.2 1 GB Sony UK
Happy to assist in testing - let me know what’s involved.
