Topic: upgrading from a sysupgrade.tar

The content of this topic has been archived on 29 Apr 2018. There are no obvious gaps in this topic, but there may still be some posts missing at the end.

I couldn't find any info on how to update from a linux tar file. I found info on how to update from a sysupgrade.bin file using the Luci interface, but there is no bin file for my system. The file that I downloaded is:



drwxr-xr-x buildbot/buildbot 0 2017-02-05 04:06 sysupgrade-linksys-viper/
-rw-r--r-- buildbot/buildbot 1933640 2017-02-05 04:06 sysupgrade-linksys-viper/kernel

Routers with NAND flash use a tar file instead of a bin.
You just run sysupgrade on the complete tar file as it is, sysupgrade knows what to do.

so I just put the tar file somewhere, e.g. /tmp, and type "sysupgrade /tmp/<file>.tar" ?

Download the file to /tmp because it is a RAM disk.  It won't take up flash space (which NOR flash routers usually don't have) or wear on the flash chip.

OK - thanks.

The discussion might have continued from here.
