Banana Pi OpenWrt One AP 24.03

Hello dear forum community,
I am new here and have no experience with OpenWRT products.

Today I received a new Banana Pi OpenWrt One AP 24.03 Router. Unfortunately, the device does not seem to work. The three LEDs on the front remain always off. Inside the device, the power LED is lit. Pinging the router 192.168.1.1 timed out .

Does anyone know whether the LEDs (Boot, OK, ACT) do not light up under certain circumstances?

Is there some hardware documentation available?

You obviously tried both ports ?

What's 24.03 ?

Keep in mind that this devices requires USB-PD with 15 V - XOR PoE for powering it up.

If in doubt, connecting the (USB based-) serial console with a USB-C 'charging' cable is the easiest option to get an idea what's happening.

Unfortunatly I could not connect to the device via console USB. The device is recogniced by Windows as "Open WRT One" but PuTTY SSH 192.168.1.1 port 22 responds with "Network error: no route to host", then PuTTY goes inactive.

I would expect new out of the box device at least should bootup. Since the LED "Boot" is not lit up at all I'm afraid the device is a dead on arival, isn't it?

24.03 appears to be the hardware version

Of course you can, and it should tell you more details about what's happening.

This will be a serial connection. Take a look at the device manager which device (COMx) is shown for the OpenWrt One.

Of course. You're trying to connect it via ethernet instead of a serial connection.
You have to set up PuTTY to use a serial connection.

For now I would focus on getting a serial connection working. When you plugin the serial it should come up as a COM device.

Yes, the device presented itselve trough COM5 (115200, 8,1,NONE,NONE), however the PuTTY session did not show any activity on the serial port.

I tried to boot into the NOR/full recovery mode: Flash NAND from USB, no reaction at all.
This is a straightforward process for recovering from a failure to boot from the NAND (https://openwrt.org/toh/openwrt/one). I mean, this should work at any time, shouldn't it?

In addition there is a slight smell of "electricity" in the unit, as if something is burning.
I think it's a really bad sign, so I'll send it back and ask for an exchange.

Thank you all for your suggestions!

You might be right about something going wrong electrically. It is not uncommon for electronics to have a smell but it shouldn't be burning.
