</div>I was able to get output by adding this to my kernel parameters:<br>
<br>
console=ttyS0,115200 earlycon=uart8250,mmio32,0x1c0<wbr>20000<br>
<br>

<br>
However, the console is flooded with messages like this:<br>
<br>

<br>
I'm happy I can boot now. If I can also stop the errors, that'd be great.<br>
