NanoPi NEO2 net port issue and don't boot

[abgenis]

Dears,

I have a NanoPi NEO2, when i connect to energy, net port's leds (green and yellow) are on and it don't boot. This happens with or without sd card.

Any suggestion?
Thank you.

Hello, if you are using an SD card, make sure it has a valid and compatible operating system image (like Armbian or another supported OS for NanoPi).

Have you tried connecting the NanoPi NEO2 to a serial console (via UART) to check if there’s any boot log output? This can help determine if the board is hanging during early boot or not booting at all.
