Starting with 15.3, the Teres-I is almost fully supported by openSUSE; the distribution runs out of the box once a custom boot loader is installed.
There is a staging area for the work in progress in OBS
-- Caveats --
There is no automated image creation yet. Things to watch out for when doing this manually:
- shorten the GPT
The A64 reads its SPL from absolute address 0x2000 (8kiB) from the (e)MMC. A GPT with only 56 entries will end just before that point, and a partition starting there and extending to 1MiB is the perfect place for u-boot-sunxi-with-spl.bin .
- modify U-Boot environment once installed
The USB keyboard is slow to come up, and the audio jack is connected to the serial console by default. Add
usb stop; usb start;
gpio set PL9
somewhere in the flow of automatically executed scripts.
- MMC driver loading is racy
Occasionally mmc-blk grabs the interface of the WiFi/BT chip; make sure the rtl8723bs driver is loaded as early as possible.
- DRI driver requires contiguous memory.
to the kernel command line. Otherwise the screen will stay blank after the EFI FB has been decommissioned.
For complete graphics support, cma=256M is probably a better choice to offer more RAM to the graphics engine.
