I have a Cisco RV320 which uses a mips64 processor AFAIK. Is there any chance to get openwrt in this device? There's a known exploit which would give access to the busybox shell, but not sure how to continue from here. I am willing to put it out for any interested developer.
Hardware specs: https://wikidevi.wi-cat.ru/Cisco_RV320
There is a single device with this SOC that is supported by OpenWrt: https://openwrt.org/toh/ubiquiti/edgerouter.lite
So it's not impossible, but it needs someone to add OpenWrt support for the RV320.
I'd love to do it but it's really not my area of expertise. Someone willing to help?
