Kali Linux on RPI

Hello all,

First of all, a thank you for all the tutorials on this site. It's been super helpful and fun.

So, my question is, how do I install Kali on a raspberry pi. I have done some research and found https://null-byte.wonderhowto.com/how-to/hacks-mr-robot-build-hacking-raspberry-pi-0163143/. This explains how to set up a raspberry pi as a hacking device. After following the first few steps, I get stuck at step 4 with an error on my screen: end Kernal panic - not syncing. And a line after that: random: nonblocking pool is initialized.

After looking around a bit the only fix for this seemed to be to rewrite to the SD card, so I did this twice. It didn't work. Does anyone here know anything about Kali with a raspberry pi, and if so, what was your experience while installing it? And does anyone know how to fix this error?

Context:

I want to use the raspberry so that when I turn it on (with a phone charger), it will automaticly find the strongest WiFi AP and DoS it. The program works on my laptop.

Thanks a lot in advance :)
