svenskon,

You write: "I manged to install Openwrt 21.02.07 from the WN570HA1 with barley no Packages"
How much free memory after running v21.02.x is mentioned in OpenWrt Status page?
Could your device be running out of memory, 64MB is not that much.

WS-WN570HN2-A-V1.2 looks different to WN570HA1, why tried this version?
What are the differences between these two devices?

I can not find anything else besides: Support for WAVLINK N300 - WL-WN570HN2 - #7 by mecsfm
Firmware was available, but it's not openwrt, but most probably a fork-of-openwrt.
Doubt if that is still available / usable.
Better try a minimum package from the OpenWrt Firmware-Selector

For a sysupgrade the machine needs at least enough free memory to hold the new firmware file.

The lots of jffs2 errors pointing to wrong mtd partitioning or something, that should be fixed first.
