What is different between Image and Image.bin? I could not find the expression in any of the linux/arch/arm64/...Makefiles.

Is it just Image renamed to Image.bin and this somehow makes a difference to bootgen? I switched to the Image-mymachine.bin symlink in my DEPLOYDIR and it makes no difference. I also tried loading my DTB at the same address as you, no difference, of course.

I am booting on SD, are you?

I see two FSBL banners in your pastebin (https://pastebin.com/Um1vmqpc)

Shooting in the dark here... but is the FSBL copying itself to RAM then restarting? Or did you just copy/pasted two lines by mistake?

Could there be some configuration missing from my kernel defconfig perhaps? (I will investigate this now.) Or some bad/missing configuration from our handoff file? I am still using the one generated by vivado 2018.3. Should we align this now to be sure?

I will try and build these products for zcu104 then do deep comparisons of config files and generated code. Perhaps if I can swap in my psu_init.c/h I could try and boot it on my board...

Anyway thanks for answering my questions. I will really make sure to send in patches for this alternate boot flow.

Cheers!
