Developer help requested.

It would be great if someone could help fix 25.xx for the Sitecom WLR-8100.

### Describe the bug I upgrade my Sitecom WLR-8100 from a default 23.xx to 25.1…2.0 rc1 using sysupgrade unchecked "keep settings". All seems normal as before, same LED behaviour and can safe boot as well using one of the buttons. But no access, not via web LUCI, not via SSH. I had this device spare so I use this one to test. But I will not upgrade the two I have in operation before I know they will be working with 25.12.x. I'm no developer, and only user of OpenWRT. I will be able to access via serial, I need to solder the headers, but that's oke. Is there any chance this device can be included for further support? It's a 128mb/16mb device and capable of around 200mb/s WAN speed. Although I only use them as access points. ### OpenWrt version 25.12.0 rc1 ### OpenWrt release 25.12.0 rc1 ### OpenWrt target/subtarget Ath79 ### Device wlr-8100 ### Image kind Official downloaded image ### Steps to reproduce Just upgrade it. ### Actual behaviour No access, no LUCI, no SSH, but normal LED activity. When connecting a LAN cable, the corresponding LED starts blinking. ### Expected behaviour _No response_ ### Additional info _No response_ ### Diffconfig ```text ``` ### Terms - [x] I am reporting an issue for OpenWrt, not an unsupported fork.

The bug might have been found with some help on Github.

I have been able to flash my WLR-8100 to 24.10.5. I’m available for testing.

The issue seems to be the same for WLR-7100. CRC32 is miscalculated because of incorrect env-size expectations.
