"Which device prototype or a development board do you suggest?" - got to be one of the most frequently asked question in the embedded workspace. Last year EOSS/ELC'23 was no different and we ran into similar questions around Android development boards. That planted the idea of enabling a community around the development boards or devices that provide decent AOSP (Android Open Source Project) support.
So we started working on The Devboards for Android community initiative
https://devboardsforandroid.linaro.org to enable a collaborative space for AOSP system developers. We briefly talked about it at the Android Microconf at LPC'23 as well.
Overall idea of this project is to provide an umbrella space for collaboration and consolidate all the resources about the devices that are known to support AOSP reliably. For each supported device, links are made available to the kernel source, local manifests, device specific files and binaries (like bootloader, firmware, HALs) and documentation. We hope that this initiative will be instrumental in sharing and co-developing features like generic HALs across multiple devices and possibly enabling the supported devices with LAVA CI in the future.
