I got my brand new Raspberry Pi 2 B today and I have a problem very similar to this one: [Solved]Raspberry pi 2 stuck on boot
The boot up stops at exactly he same output. I don't see no rainbow colored square in the upper right corner. Also, this is my second Raspberry Pi 2 B. When i use the new Pis power supply with my old one, the old one boots up and everything is fine. If i try to boot the new Pi with the old ones power supply, it hangs, too.
I only attached a USB keyboard (very simple, no power consuming displays or anything like that) and a HDMI Cable.
Any Idea what's wrong?
Used the old Raspberry PIs microSD card with the new Raspberry Pi -> works like a charm. Used the new microSD-Card with the old Raspberry Pi -> same Problem, hangs during boot up. Seems to be an issue with the microSD card. Think i'll have to buy another one.
Edit 2: Yesterday i flashed the new SDcard at least 4 times with raspbian, also tried an older release (2015-02-16), and every time i dd'ed the card back, trunkated the image and compared the originals md5 with that one from the SDcard. The hashes matched everytime.
Today i gave it another try and it suddenly worked. The only difference to yesterday is that i used a different SDCard reader. I tried it again with the first SDCard reader -> didn't boot up, although i veryfied the hashes again. But when i verified the hash of the image written with the old card reader with the second cardreader, they didn't match!
Seems that my card reader is a bit (deterministically) weired.
