Add support for D-Link COVR-X1860

Hi @all,
I have successfully flashed openwrt on my two APs. However, something went wrong with the second attempt and now it is no longer accessible.
Reset does not seem to work. How can I recovern the AP?
Do I need to flash over serial and how?

Is recovery still working? Set the IP of your computer To, keep the reset button pressed while powering on the device and check if you can reach with a browser.
If it works, you can flash the recovery image there.

No is not working, can not ping

Looks like the exact same implementation as in my tool, the encrypted payload digest is still okay, but the decrypted image is weird in terms of padding, no idea what D-Link did to generate this... :man_shrugging:

I remember from DAP-X1860 that ping didn't work but the recovery web interface was working anyway, can you check?
What was the last thing you did with the device when it was working?

sysupgrade -f openwrt-ramips-mt7621-dlink_covr-x1860-a1-squashfs-recovery.bin was the last I did

I wouldn't want to go back to the original, but unfortunately the mesh doesn't want to work, it's greyed out when creating and I can't rewrite the ssid..

Blink red ?

only red, no blinking

openwrt-ramips-mt7621-dlink_covr-x1860-a1-squashfs-recovery.bin is not intended to be used with sysupgrade, openwrt-ramips-mt7621-dlink_covr-x1860-a1-squashfs-sysupgrade.bin would be the correct one in this case.
Not sure what is happening when you sysupgrade with the wrong image, but my expectation is that recovery mode is still possible afterwards because the boot loader is not modified.

Also no red blinking when you try to enter recovery mode?

what are the settings to connect over ttl?

U need click reset and put power on and wait for blink.

ok, now is blinking red and the network card show a link is up
but no website is possible to open

U need manual write lan IP like mask

ok, found the problem the recory page is on now I can upload a file, with one is the right for this?

ok was successfull but openwrt only over ssh is possible. Red LED is fast flashing

Did you reset the IP configuration to DHCP?

No set a static ip, dhcp is not working. Ping to is possible and also ssh.
