I downloaded this .img file (rock-5b_ubuntu_jammy_kde_b33.img) and flashed it on TF card.
Then i inserted TF card and made SBC power on.
But the display didn’t show anything.
(10inch 1280 X 720 and 16inch1920 X1080, both I can’t check those refresh rate…)
Does anyone else have a similar soituation?
If the person who has same situatishon, I would like to know how to fix it.
