Folks at TP-Link have released a new model recently, C54, specifications for which can be found here: https://www.tp-link.com/en/home-networking/wifi-router/archer-c54/
I couldn't find any information on the amount of Flash/RAM the router has except for one website, https://www.batna24.com/en/p/tplink-archer-c54-wifi-router-rmmjj , which states that the router allegedly has 64 MB of RAM, so I presume that Flash may have 8 MB in this case.
The question is, can this specific device be supported by OpenWrt, and if so, by which time (rough approximation, e.g. Q3 of 2021, etc.) it will be developed?
