Issue booting RPI2 B (v1.2)

Kris Moore-2

I've been toying around with a bunch of RPI2's here (using
11.0-RELEASE), and so far so good. However I just ordered a new batch of
them and they all get stuck at the "rainbow" screen. After further
investigation, I noticed that they were marked as "Raspberry Pi 2 Model
B V1.2", and all my other units are V1.1. Just for kicks, I tried
rasbian, and that works fine.

Is this possibly an issue with U-Boot being too old for this revision?
Any other ideas?

It is listed as out of stock but http://www.mcmelectronics.com/product/83-17791 agrees in its description:

I know that http://ameridroid.com/products/raspberry-pi-2-model-b-1gb-ram 's old page for V1.1 has said "DISCONTINUED" for some time.

Oh, that's a bummer. I was afraid of that, since the 2's are getting
harder to find now. I would imagine its not worth looking too hard at
this, since support for the Pi 3 is starting to land ;)

WTF - why can't they use a different name for something completely
different.
This isn't just a PCB version change, especially not a change in a
minor number.
In other words I need to keep my thumb on the Pi 2s I recently got,
since those are the old ones.
Got mine just 2 months ago directly from RS, maybe they still have a
stock on the previos Pi 2.

The modern versions of the official operating system supports both V1.1 and V1.2 of the board, allowing existing programs to continue to work on newer boards. (At least that is my understanding.)

It is a different SOC but with the new one configured for use for extreme compatibility with the old one from what I can tell. (User space code, anyway, including using official interfaces to things on the board.) They do not claim to support 64 bit at all: just Cortex-A7 compatibility.

For their primary target customers it is not "completely different".

That other operating systems might choose to go in a different direction is not a consideration for them: what they support is very compatible even though the hardware does not require such configuration.

(I'd have preferred RPI2C vs. RPI2B for naming at least. But I'm not using the official materials generally so the issue is more noticable.)

It is not just other OS.
There are tons of customized Pi Images out there for different kind of
application type of things, which can't boot until updated by the vendor
first.
Usually this wouldn't be a big deal, since you boot them and start an
update.
Many kind of common use cases run customized kernels e.g. to run SPI
based displays.
Gratend - force them to use updated Linux kernels seem to be wise given
the recent Linux kernel bugs, but on the other hand I guess the timing
is so bad that they might miss that fix.

This whole Rev 1.2 thing is senseless for me after all.
Just looked up the prices at element14.
The Pi 2 is still slightly more expensive than the Pi 3.
Why would anyone buy a Pi 2 vs Pi 3 if not for compatibility reasons?
