Thanks for the reply, yes I am using HDMI + Keyboard. And edited the uENV.txt file. After following the instructions on the ipfire site, i then watched some youtube videos as well to make sure I hadn’t skipped over anything (I had not).
From what i have been able to google I am getting some kind of kernal error, that isnt allowing the raspberry pi to boot. Although, this could be completely incorrect as I dont have the personal knowledge to test this theory.
Edit: I realise I am not supplying much information as to what is causing the issue and making it very hard to trouble shoot. But I am not getting much info to actually work with, so if there is something I can do to provide more info to help please let me know.
