Can orangepi boards work?

[jandy123]

Thanks a lot for sharing your work!

Before buying another SBC board and since I have a few orangepi ones, could any of them work?

Thanks!

Related #134. #123.

I believe if the board has USB OTG and Wifi+BT, it should work. Though we need to build an image for whatever board we want to run this on.

Here are some high-level steps to add a new board.

• See if the buildroot version we use supports this board. Adapt the appropriate defconfig for the board for the project. See existing defconfig files in aa_wireless_dongle/configs.
• See if this builds. We need to apply some patches to the linux kernel. Make sure the patch is compatible with whatever version the board is configured with. If not, update the patch appropriately for the board.
• Once built, test and see if any additional configuration/changes required in the image.

Thanks for your answer and for the nice work!

But, as I understood, some orangepi boards do not have the DMA driver, meaning that the CPU will have to do a lot more to manage the stream transfer. Also I actually have orange pi lite, pc and zero v2, which do not support bluetooth, so I'd need yet another usb dongle... I think I'll just drop the reusing-orangepi idea.

If it is to bite the bullet and buy a rpi, which of the supported boards zero W or zero W2 run better? Also, how do any of the rpi boards compare to the cheap Chinese dongles, going for less than say 40 euro? Or, what about an older android box which can run debian linux? Regarding android, I could also just repurpose either the box above or an old phone and try your aawirelessgateway https://github.com/nisargjhaveri/AAWirelessGateway?

Sorry for the many questions, but I'm new to android auto and trying to understand the performance tradeoffs, options, etc.

Not to mention, but my wife's Huawei does not support android auto, so is there any way to use another fully-flaged android "gateway" without requiring any android auto on the client phone?

Thanks again!

Hi, i'm trying with an Banana Pi M2 Zero, this board have bluetooth and WIFI, because already i use it for another projects. I try to recreate the boards with the default options on buildroot but i understand the patchs in the repo are most important to convert in a android device for the car, but with many intents, the board not generete anything, i coulnd't try check with HDMI if something is happend.

The file is called bananapizero_defconfig and this the config inside the docker-compose.yml

`

Can you see some error here maybe?

Thanks!
