this device currently build-ed same target firmware with openwrt 18.06 and boom no error while upgrading but device not able to come up.
any suggestion over here as i suspect its kind of partition issue while upgrading a firmware .
You will probably need to reconfigure going from v15 to v18 or v19. Have you tried not keeping settings on the device (after making a backup and saving it somewhere safe, off the device)?
yes i tried with not keeping settings.
does there is a difference with UI upgrade or upgrade from shell i am using below command.
"sysupgrade -n /tmp"
its GL AR 300M .
With or without NAND?
As I recall, anode chech the GL.iNet forums, you may need to use U-Boot to “cross-grade” from NAND to NOR. I don’t recall if OpenWrt has a NAND version of the firmware for v18.
NOR flash only.
openwrt-ar71xx-generic-gl-ar300m-squashfs-sysupgrade.bin (file name)
Should upgrade smoothly. Perhaps the wrong socket for the Ethernet or that OpenWrt uses 192.168.1.1 (different than GL.iNet default) and the wireless is off?
i kept default wireless is on in code, with custom SSID i wont be able to see anything .
