The old Pi2 uses the BCM2836 SoC, the newer Pi2 uses the BCM2837.
Old 32bit only, new 32/64bit.
So this should work on the new Pi2, but I don't have any.

Gentoo32?
I have only found DIY build instructions, no ready to go image?
Not all Pi2 manufacture uses the bcm2837, some are still made with the bcm2836.

Hmm that could be confusing if I needed a lower power WiFi-less 64bit Pi ;)
BCM2836 rev 1.1 , BCM2837 rev 1.2?

Hey, which is the lower power Pi2?
32ibt 2836 or 64bit 2837?

I suppose just for Ethernet gadgets the Pi2 rev 1.2 would be better than Pi3B or 3B+.
Is there a Pi2 rev1.3 with the metal top 2837 clocking at 1.4GHz?
Probably not, need a PCB redesign to get the heat out, 1.3GHz?
But old lan chip, so not as network fast as a 3B+ :(

Hmm Pi2B+ in the works?
Rhetorical question - no answer expected :D

Yes, afaik the rev 1.2 RPi2 has a 64-bit-capable SoC, whereas the earlier revs do not.

I have been informed by a user that the gentoo-on-rpi3-64bit image will boot on a rev 1.2 Pi2 board, provided that an appropriate dtb is present in /boot, by e.g. mounting the first partition of the image on a pc, at /mnt/piboot say, then doing.:

Code: Select all

# cp /mnt/piboot/bcm2710-rpi-3-b.dtb /mnt/piboot/bcm2709-rpi-2-b.dtb
Unfortunately I don't have a Pi2 to test this out.

do we have 32bit for Rip2 ?
A bootable 32-bit Gentoo image with integrated desktop etc. would definitely be possible but it's not on my todo list. There are of course the usual stage 3s etc available if you want to roll your own.

Hello,

I tried to install Team viewer on Gentoo but it doesn't work. What's the correct command to install it? Sudo emerge teamviewer does NOT work.

Thanks!!

Solid924,

Apologies for the delay in replying, I am currently travelling with only very intermittent internet access, and will respond on my return (last week of August).

In the meantime, please post a topic on the ARM subforum of the Gentoo board for support.

Best,

Sakaki
