wilc1000 soft AP configuration

[ksathara]

Hi, I have managed to compile the driver and integrate with Raspberry Pi CM3+. The station mode seems to be working fine. I just tried to implement AP mode as per "https://www.raspberrypi.org/documentation/configuration/wireless/access-point.md" and having some problems.

1. I dont see the AP
2. After some time, I get the kernel oops

Hi,
I was just pinging www.google.com

From dmesg -w, I can see the point at which this kernel oops pops up.

There seems to be adding of some key happening just before the oops.

Can you add more logs to handle_key() to see where exactly it fails?
you can also try the driver and FW from the dev branches since they have some updates

[AdhamAbozaeid]

@ksathara , any updates on that?
