Will this get supported by OpenWRT?
I only see A1 and B1 supported.
If you have the device we could try to figure that out.
You will need first to find manufacturerproduct page best with firmware upgrade files.
I have the device with me. Can you let me know, what do I need to check?
I only found this datasheet from the manufacturer's page.
Try to collect OEM boot log from OEM firmwares web interface for starters:
- Amount of memory (64MB works as simple AP, 128+ good)
- CPU and SoC type (should be same as on already supported device)
- amount of flash storagre (mtd and ubi) (16MB min, 8MB already needs extreme compaction of installation for rev 23)
- wifi hardware (same consideration as SoC)
- network ports can be derived from public specification
The upgrade image would partially jump over absolute need to connect serial connector to pcb in open device case later.
most of this can also be obtained by opening the device, if logs aren't available through the webUI.
So here are the startup logs (debug level).
Can you please take a look?
Not a supported SoC.

16MB flash 128MB RAM
rest of chippery is realtek, wired should be working, wireless is vaguely described. But not before SoC is supported, i.e in years, if at all.
so , no hopes ?

Thanks for effort documenting HW though.
as in , any idea when this SoC will be supported?
Not in next stable release nor release after, there is no publicly known active work on it, like in form of test bootable images.

Realtek doesn't really have a good track record of adding their SoCs to mainline Linux.
I wouldn't get my hopes up.
