Tips, how to install linux without monitor

[Antibiotic]

Hello,

I have one small router, here tech details:
https://openwrt.org/toh/hwdata/gl.inet/gl.inet_gl-mt2500_gl-mt2500a

The problem, they are using very old openwrt version and new version still not supported. I s it possible to install on this device Linux ARM64? This router have only one usb port and no any connection port for monitor support.

You might have better luck asking on the https://forum.openwrt.org forums, since this is not a linux forum.

@Antibiotic is the MT2500a different from MT2500 (doesn't look like it is)? In SNAPSHOT there's an image in the firmware selector for it:

Added in commit below (April 2023) plus a few later commits with fixes:

    Known Issues
    ------------
    U-Boot vendor recovery does not seem to accept any images, neither
    GL.iNet images nor OpenWrt images. Recovery requires serial access!

    Installation
    ------------
    Upload the OpenWrt sysupgrade image to the Gl.iNet Web-UI. Make sure to
    not retain existing settings.

I see, that's not aworking solution then for you. Searching the OpenWrt forum is going to be more helpful here. I'm sure there are some people who have this device and maybe the similar issues as you.

A standard ARM linux would need a lot of work I think. OpenWrt is based on a Linux kernel but with tons of patches, plus all the device specific changes for the MT-2500.

That newer openwrt image is certainly what I would try. You should be able to netboot it so no 'recovery' it necessary if for some reason it doesn't boot. You'd need console access though.
