Hi, Currently I am working to minimize the filesystem for one of my project. In my project I only want to add support for USB & Wireless (wil6210). To minimize the filesystem I disabled the unwanted things like Iptables, VLAN, VPN, Ethernet support etc from .config and brought my image size from 22 MB to 8.9 MB. Now when I did the ifconfig wlan0 up I get below error: wil6210 0000:01:00.0 wlan0: wil_open: Failed to register with NSS In Ideal case when I enter the above command I should get below logs: wil6210 0000:01:00.0 wlan0: wil_open: Registered with NSS I checked the dependency for wil6210.ko module and they are cfg80211 & compat and they both are enabled. Can any one tell me which libraries/modules I have mistakenly disabled which is causing this error. -- Thanks & Regards, Arjav Parikh
