I don't understand your question. Write in detail what you are doing and what the problem is.

I don't understand your question. Write in detail what you are doing and what the problem is.

1. HDMI has no show, SSH login is normal; The equipment used is Phicomm N1

[150balbes]

check your DTS settings.

[Hnmtc]

The DTS is consistent with the normal display DTS file, and whether the DTS problem can be excluded.

[150balbes]

The version of the image ?

[Hnmtc]

Problem version: 20190712 5.2.0 -> 7f258e5d352505dcb38ce871eff0d72e1ef94206 20181018 4.19.0-rc7 -> 5e7b9687460cf9111ad6efb8e7857825542a27c5

Version image Armbian

[Hnmtc]

Debian 9

[150balbes]

I ask the version of the image Armbian which does not work HDMI.

[Hnmtc]

I don't quite understand what you mean
