My experiences so far with 8.1 on SD card on a 2GB rock64 are that:
- Imaging with etcher gave a "not bootable image" warning, but it booted just fine. Etcher probably just doesn't know how to check Android images are valid.
- If you have flashed the SPI with uboot when playing with linux images, you need to either jumper pins #23 & 25 or erase the SPI flash as uboot can't boot the android image.
- It did take somewhere between 5 and 20 minutes for that first boot (I walked away for a few minutes) but subsequent boots were less than 2 minutes.
- Ethernet just plugged in and worked
- Didn't get WiFi working - neither the store AC wifi nor a nano realtek wifi adapter (which both work fine under linux) was detected even after a reboot.
- As configured, Google Play Store does not work, but as geno suggested, browsing to www.apkmirror.com, searching for "Google Play Store (Android TV)", downloading the APK and installing it (10.5.10 in my case) worked just fine. Google Play Store then loaded fine, and I was able to enter my google account details just fine.
- RKMC seems to work just fine, although some videos made it just crash. However, it doesn't seem to detect the screen size fully. The main launcher and most apps are full screen, but RKMC and the media centre apps leave the right and bottom of the screen blank, and changing overscan settings doesn't work as it really does seem to think the screen is that big. Image of this attached, with a red outline to indicate where RKMC seems to think the 'active' area of the screen is...
