Border Router OTA using WiFi

Hi. I’ve been away for a while and now decided to come back to try and tackle this problem. I am still unable to figure out how to configure a static prefix. I selected PREFIX_CONF=static and IPV6_PREFIX as 2001:db8:: and IPV6_ADDR as 2001:db8::1. I also set CFLAGS += -DCONFIG_GNRC_IPV6_STATIC_ADDR_UPSTREAM=<pid>. I tried with various pid values, from 1 to 10 but none of them work.

The interface auto-selection is still probably selecting the wired uplink because the ethos “termprog” is still running when I run the terminal and if I try to set UPLINK=wifi manually, I’m running into a “RIOT kernel panic” problem.

Is there anything else I can check or am I doing something wrong here?
