Sysupgrade with 2 partitions

Installing and Using OpenWrt
1

Hi,

I have a linksys device and I would like to keep one partition with linksys firmware but everytime I sysupgrade, the sysupgrade goes to the second partition, so I guess I need to always take the factory image and flash from oem firmware?
thanks

Yes. You don’t identify your model but there have been a couple of models that have had kernel space changes.

Take a backup from your OpenWrt config, reboot back to OEM partition, load factory.img, restore your OpenWrt backup.

See(https://openwrt.org/toh/linksys/wrt1900acs#firmware_recovery) for reference.

I have the linksys ea8500

That being the case, see the Device Page for your device: (https://openwrt.org/toh/linksys/ea8500#flash_layout).

There has been a kernel size update, so you will definitely need to use the factory.img. I don’t know this model well enough to assure you can restore backup with your requirements - see the forum link discussing this from the device page.

I made 2 different threads, I guess your answers are for my other one about image too big? Anyway, I try to flash from oem and it says that my open wrt image is too big

Just saw it. Different issue.

My EA8500 was flashed openwrt, every time I powered it up, it always goes to openwrt, no more linksys factory fw.
When I do the openwrt fw upgrade, I always use the openwrt luci gui.

I never use linksys oem fw flash openwrt successfully.
At the first time, I used TFTP server + UART-USB tools to install openwrt.

I know EA8500 has 2 partitions, but the second partition seems useless for openwrt.
