Dualbooting AR300m

Hi everyone
I’m not that technical. Can I dualboot between the GL firmware and the latest openwrt 19 on my AR300M?

How can I install the latest openwrt?
I want to keep the stock firmware too.

you can use gl-inet firmware on nand and vanilla on nor… i used to do like this… i don’t have the device anymore… gifted to a friend.

Method 2: using the switch
This is only valid in the new uboot (from Mar 2017).

First ssh to the router and set uboot env boot_dev

$ fw_printenv
$ fw_setenv boot_dev on
$ reboot

Then when the router boot, the router will choose which firmware to boot using the hardware switch. 1. Left side (near the reset button) → Nand flash 2. Right side → Nor flash

To disable using the switch to choose firmware function, clear boot_dev variable.

$ fw_printenv
$ fw_setenv boot_dev
$ reboot


edit: firmware install is http://downloads.openwrt.org/releases/19.07.2/targets/ar71xx/generic/openwrt-19.07.2-ar71xx-generic-gl-ar300m-squashfs-sysupgrade.bin

is this also do-able with the ar750?

answering my own question here.
edit: nope. might happen down the road for the ar750s but no plans and currently only for 300m.
note 300m may be only for 2.x software for dual booting.

NO. AR300M is the only one support dual-boot.
