Pi Zero 2 released

@stuartiannaylor You're getting offtopic here and bashing other forums - which try to provide support for all sorts of users - is not welcomed. If you registered here just because you've been blocked/banned in the RPI forums, I don't think is going to be much help - we're not a general RPI support forum.

Just a heads-up for those experimenting with the new Raspberry Pi OS Bullseye release on the Zero 2: From what I can tell, the Zero 2 does not get any hardware accelerated graphics right now. The print-out below is from a fresh and fully updated Raspberry Pi OS desktop installation.

@brunnis Cheers as I am say and no I didn't join just to bash other forums, I can not get other info because of what I think is a stupid ban, but hey.
I joined to give RetroPi a bit of an OC then Bullseye turned up, so if anyone fancies posting and asking on the raspberry forum please do, hence why I said.
I guess I am still smarting at the inconvenience, but if someone will ask as I can not.

I wonder if its the GPU memory as guess the default is 64Mb on the Z2.
I think gpu_mem= may have to be =256 currently but seems to kill the boot

Anyone know which Pi's work with hardware acceleration P3b? Or is it just the Pi4 at the moment?
P3b also = llvmpipe
Pi400 = Mesa 20.3.5
glmark2 on the pi400 is 234 which from memory think is a reasonable bump but maybe things need >=2gb as noticed the dma (coherent_pool) was set to 1gb for all

So going back to the old buster image with fakekms initialised in raspi-config

Default clocks Z2

Which is interesting as running on a Pi3A+ I got glmark2 Score: 79
v3d_freq=400 core_freq=500 seems to make no difference glmark2 Score: 90? Thought core_freq would but seems just v3d_freq
arm_freq=1400 over_voltage=6 to equal the pi3A+ again makes no glmark diff but expected

v3d_freq=400 sdram_freq=550

From what I can tell, the Zero 2 does not get any hardware accelerated graphics right now.

This post on the RPI forums seems relevant:

[...]
glamor on pi0-3 actually slows done composition, hence the disable, but unfortunately means that gl from windowed apps (e.g. glxgears) is also disabled.

I encourange anyone experimenting with the new Raspberry Pi OS ('bullseye') to use a separate topic and report their findings.

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.

stuartiannaylor

@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?

Luddo183

@george-spiggott
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.

Brunnis

@george-spiggott said in Pi Zero 2 released:

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

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).

stuartiannaylor

@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.

https://www.raspberrypi.com/documentation/computers/config_txt.html#overclocking-options
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

@matchaman said in Pi Zero 2 released:

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.

BenMcLean

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.

cnoto

@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:

ParadoxGBB

@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.

retropieuser555

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

x_Speed

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

mitu

@tjfisher84 said in Pi Zero 2 released:

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.
