However, I do not want to disappoint you, but the difficulties and challenges just started for you with the 7530... Please take a look here and there.

Even if you flash OpenWrt on the 7530, you will find out that you need to juggle with the interfaces, device and vlan setup to get what you want. I simply wanted to simulate a standard WAN port (because the device lacks a physical WAN port) on an existing LAN port, and isolate the traffic as if it was a WAN port (i.e. make 7530 a standard (NOT DUMB) router with firewall), and I gave up in the end, with even considering selling the device on eBay. The configuration of this ipq40xx device is $#..show at the moment (not sure if it will be permanently like that); I have been told that if you experiment with the snapshot build, things are much (?) better, but then you need to figure out how to set up luci without having access to interenet etc etc. Even after you finally solve that, you probably need to do the same process over and over each time you need to update your build, until the improvements become part of the standard release image (next year probably).

Just use a current snapshot image and these problems are all gone. It is unfortunate that this is currently necessary, but often these builds are very stable. My box currently has an uptime of 60+ days with a DSL uptime of 60+ days. If you want DSL support, you need a custom build anyway since DSL support is probably not coming in the near future to an official release. Take a look here for a discussion on DSL support: Adding support for VRX518 (and maybe VRX320)

It's a bit hard to find in the thread, but a working branch with DSL patches applied is available here: https://github.com/dhewg/openwrt/tree/vr11

That said, it's also possible that AVM has changed - once again - hardware: My 7530 came with an unsupported flash chip and I'm unsure if the patch made it into 22.03 or is only applied to master. The symptoms, however, are different, i.e. the initramfs image boots fine but flashing fails.
