RAM size detection wrong - Xiaomi ac2100 - MT7621

Solved by adding:

memory {
device_type = "memory";
reg = <0x00000000 0x8000000>;

to the dts file.


I am actually building OpenWrt for a new device "Xiaomi ac2100" (MT762). The board has 128 MB RAM, but "free" and luci report 256 MB instead. Is there a way of manually tell the system the proper RAM-size, or anything I can add to the build files to get it recognized properly?


There are a few threads about it already, maybe they are helpful?


Thanks, I already solved the problem!
