I was able to boot Linux from the SDK on just a VC707 with no other hardware.
This is the boot message.
Is there error while booting expected or is something wrong? Thanks.

Looks like it worked to me. If you are worried about the stack trace, don’t. It’s a bug in the OF layer of Linux 4.15 that just means you end up missing a few optional files in /sys.

Yes. I was worried about the stack trace. Thanks for the explanation. Thank you Wesley.
