New user - Help needed

I just got the SBC from AliExpress, Mq-Quad H618 version 1.2.
Power up, nothing on screen.
Burn image to TF card, power up, nothing.
What can I check?

?Is there any formal support


How to burn image to TF card?

There is poor software support… only Android TV snd I need Linux

H616 : tina-linux , debian, android
H618 : only android

If there is no Linux image planned in the near future, I will return the SBC.
Thank you

Since allwinner does not provide 618 linux resources, there will be no linux os support in the short term.
