Pi Zero 2 released

George Spiggott

Is the Bullseye OS release significant news? Is it worth starting a thread for?

I see a lot of people regarding the Pi Zero 2W as an up/side-grade for the Pi 3A it seems to share a lot of attributes but is smaller and cheaper.

@george-spiggott Z2 can clock same as pi3 but does lack the DSI (display) connector.
So guess if HDMI its ok, not sure how popular DSI is?

The Pi Zero 2 is essentially a weakened, shrunk Pi 3. In they way of handhelds and portable projects, it is a godsend, but again, is not a substitute for a good Pi 3.

Yes, it's significant. The biggest change is that it now defaults to full-KMS for all hardware. It also finally bumps Mesa to a newer, albeit still outdated version (20.3 vs 19.3).

@luddo183 Also only weakened via the DTB frequency definitions as all Pi3's are essentially the same.
The diff between the 3b & 3b+ is purely a redesign of the PCB for thermal distribution that they gave a factory OC.
Same chip though but the Z2 is all ceramic package with a ram sandwich on top, so a bit harder to cool, but they seemed to of done a stellar job with the PCB heat distribution with a much smaller PCB.

Has all the settings whilst some of the over_voltage has already been applied to the 3+ so starts at zero again.

The only thing that is puzzling me is that setting v3d_freq=400 on the Z2 so its same as the Pi3's seems to provide 10 more points on the glmark2 score which is good but was expecting the same?

The Raspberry Pi 4 Vulkan Driver "V3DV" Merged Into Mesa 20.3 and don't know if that is ever coming for lesser Pi's

As for RetroPie, should the existing 2/3 version be compatible? I hope so!

The 4.7.1 image is not compatible, but a weekly snapshot image should work.

The 07-11 images works fine. I had some sound issues, but nothing unsolvable.
Is there any place to follow the development here?
To see what's new in new images and even more important when new images are going to be released?
Didn't found that in the forum or elsewhere at the page.

Btw.: awesome work, guys! Totally love my portable CPC

Development happens on the public Github repository - https://github.com/RetroPie/RetroPie-Setup.

To see what's new in new images and even more important when new images are going to be released?

When a new image is released, it's usually posted on the RetroPie site. As for when, there isn't a strict schedule or a roadmap for it.

@mitu Hope you don't mind - fixed your link.

I am excited to get the PI Zero W 2 and put it in my GPI case. But it needs a good OS of course so I'm gonna wait until that's ready.

@paradoxgbb One thing to consider in terms of battery life is installing a rechargeable battery. I can confirm that I have successfully used these mod instructions:

@cnoto Thanks, interesting.

As I understand it you can stick rechargeables in the AA slots and can also plug directly into a USB bank if you have to as well.

My GPi case should be arriving today or tomorrow so I'll have to give it a try.

@paradoxgbb comes with a DC USB cable as well as another option. It's how I use it mainly

Since the Zero2 uses the ARMv8 architecture (instead of ARMv6 on the "original" Zero).

Which image is the correct/better one to use? zero, or 2/3?

cnoto

@x_speed the 2-3 image. But use the weekly release version

tjfisher84

@brunnis do you have a copy of the October build please? There doesn’t seem to be any weekly builds up anymore? Or are new ones due?

Thanks

Probably something failed during the weekly build and the images haven't been created.
You can install on-top of Raspberry Pi OS (Buster) (download. from here)using the manual method.

I have paused them temporarily due to my server being in the process of some updates. The last weekly build is fine to use.

BuZz

Ah they shouldn't have gone sorry. I must have forgotten to stop a cron job that removes old ones. I'll put a build back shortly.

BuZz

I have restored the images - https://files.retropie.org.uk/images/weekly/

@paradoxgbb I mentioned this in the other GPi thread, but you might need rechargeables with decent current output.

I've seen reports on Reddit that cheap low-capacity batteries cut out with the Zero 2W in the GPi case.

I am using Ikea Ladda 2450 in mine and they're fine. Panasonic Eneloop Pro are also reportedly good.
