GPi 2 with Kali

wifi

My CM4 doesn't have wifi, so I tried with a couple devices:

• this cheap and small USB with this driver
• this larger USB device with this driver

Both support monitor-mode and injection. I'm not sure, but I think kali's extended kernel has support for them buit in, but it also doesn't have Gpi2 LCD support.
