Hi,
I get one of tinkerboard 2 cards from asus seller in turkey.
It seems there is just strech image available for Tinkerboard 2. Then I tried to upgrade buster using debian arm64 repositories (using debian.org instead of debian.net which provided in source list of tinkeros), I lost the hardware acceleration at all.
I keep kernel and kernel-libc then tried it is not also worked in my situation. Probably libdrm and libmali based packages broken in buster. And also I tried various combinations to get hardware accel. But this is bad and good. Good because I see video card, bad because I cannot use it functionally.
Are you going to create and supply new images for buster because nearly stretch going to tagged as "oldoldstable" in debian repositories and 1 year later it wouldnt supplied at all.
Bests regards.
