I am a user of your company’s product: Quaderno Gen.2 A4.
I know it uses i.MX8 by NXP and Android 9 from the AOSP Project. They use the GPL License. So, your company should open the source of the device’s U-Boot and kernel.
Can you make them public to a website?
You may have the wrong place. This is a place for users to exchange information with each other. It is recommended to ask on the official Twitter account (@QUADERNO_fccl).
