@george how?

@reddfoxx Tried it but it doesn't work.

Why not use all the cases for raspberry pi 4 out there with a little modification for the minidp port? That's what I did and it is much better quality than 3D printing this one. Isn't that one of the points of making the Cool Pi 4B in the form of Raspberry Pi 4 is to use as much Raspberry Pi 4 assesscories as possible? But OK. Question for Cool Pi: What's the point of the miniDp port? Why not make 2 micro-hdmi ports like Raspberry Pi 4?

@reddfoxx Download link for the newest image?

@george Thank you. Also, please include WiFi and Bluetooth support while you're at it.

Does this version have Vulkan support? I tried to run a program with Vulkan and it doesn't work.

@大法师 Thank you very much!

Hello! Thank you for working hard during your Chinese New Year! I don't want to bug you on your break, but when you get a chance can you enable bluethooth on Android? I really need bluetooth for my project. Thanks!

Thanks for the effort but we can't read Chinese. Does Cool Pi 4B only target Chinese users? If so, that's a pity because Cool Pi 4B is a very nice board.

@george But no wifi how can I update?

@george OK. Updating loader file works. But no wifi and bluetooth in this build?

@george I tried with balena Etcher and it doesn't work.

@大法师 Thank you! Please add bluethooth support in the next version.

@大法师 Thank you, but please provide onedrive link or some other link because I can't download from baidu. Does this version also support bluetooth? In addition, does this version enable the use of the top USB3.0 port? The old version makes the the top USB3.0 port unsuable.
Thank you!

I use a Pimoroni Fan SHIM and a little rasperry pi heat sink. https://shop.pimoroni.com/products/fan-shim?variant=29210095812691

@Bret Thanks! I see you have different sizes. Does size effect read/write speed? Would it be better or more accurate to test with all same size?

Does Cool Pi 4B support parallel RGB like the Raspberry Pi 4b? I would love to put Cool Pi 4B board in the PiBoy DMG instead of the Raspberry Pi 4B.

@大法师 But it will be faster and better if you get Cool Pi 4B boards to those devs. They are willing to provide support but they need the boards. Look at orange pi, they seem to be moving at lightning speed in terms of 3rd party software support. We love the Cool Pi 4B form factor because it is 99.9% same as Raspberry Pi 4. Your sales will go through the roof if you distribute these boards to 3rd party devs in the retrogaming scene. Retrogamers love your Cool Pi 4 but they are afraid of lack of support.

@george Excellent!

@大法师 I think you meant replace "console=ttyS0" with "console=ttyS1"? Anyway, console=ttyS1 fixed it.

Perfect! Thank you!

So I wanted to experiment with Armbian and tried to flash the Armbian OS for Orange Pi 5 to Cool Pi 4B. The flash failed because Orange Pi 5 Armbian is not compatible. So I reflashed Cool Pi 4B Android 12 back, but now it doesn't boot anymore. The Cool Pi logo does not even show up anymore, just black screen. Does anyone know what happen? Did I mess up my Cool Pi 4B board? Anyway to fix this?

Ok, I was able to make it work and image has been downloaded to the board, but now it doesn't boot. I don't see the Cool Pi logo anymore. I think the bootloader or something got messed up. How do I fix this?

How do I fix this? Now my Cool Pi can't boot.

and Emulec?

Can you provide an android 12 image with wifi support?

As the title says, would Cool Pi provide Batocera, Retropie, Lakka, Recalbox devs cool pi 4B boards for support? This would expand Cool Pi 4B customer base a lot I would think.

I get the message "Android system serial console enabled performance is impacted. to disable, check bootloader." How do I disable this?

Not sure if this is the right place to report issue, but WiFi doesn't work with this build I don't think.
