Installing and Using OpenWrt
1

HI All,

using

root@OpenWrt:~# cat /etc/openwrt_release 
DISTRIB_ID='OpenWrt'
DISTRIB_RELEASE='Chaos Calmer'
DISTRIB_REVISION='unknown'
DISTRIB_CODENAME='chaos_calmer'
DISTRIB_TARGET='ar71xx/generic'
DISTRIB_DESCRIPTION='OpenWrt Chaos Calmer 15.05'
DISTRIB_TAINTS='no-all no-ipv6 busybox

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)?

Which device?

3

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.

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 .
