Down for me right now but usually https://linux-sunxi.org/A733 has ok details. Where-as collabora maintains this incredible support matrix, which generally indicates a modern want for nothing for Rockchip. https://gitlab.collabora.com/hardware-enablement/rockchip-35...

I still bought two allwinner a733 boards, on an AliExpress sale. I went with the Radxa Cubie A7z, as Radxa isn't perfect either, but much better ecosystem participants than OrangePi. https://linuxgizmos.com/radxa-debuts-raspberry-pi-zero-alter...

1. no vanilla kernel support

2. often require patches and blobs in the kernel

3. worst or nonexisting gpu acceleration

4. just not opensource in general, from blobs to drivers, to closed source boot code

why are these boards being sold as developer friendly when they are often less useful than their x86 counterparts, and very often less opensource?!
