Same here ;-) I did some more work on this, best described as copying a lot of commands from my notepad back and forth. I think you confirmed my underlying issue here: Your process is "take a FIT, move the dtb out of FIT image, apply the overlays, boot it". The documentation in overlay-fdt-boot.txt never mentions to move the dtb file out of the FIT image and it bugged me a lot that I was doing a (seemingly) unneeded step, but it seems the step is correct and just not documented.
Let me just post the (hopefully) relevant excerpts:
First of all, this looks like how I got it to work, so this tells me at least I wasn't completly off-track here.
# Re-enable fdt relocation since in place fdt edits corrupt the ramdisk # in a FIT image... env set fdt_high env set fdt_resize true
Can you give me a bit more info on your use of the fdt_resize? I know the fdt resize command and I assume thats what you're calling underneath, but I would like to get a better understanding on what is done so I'm not missing anything.
I hope that gives you some ideas how to overcome your struggle. Good luck!
I did quite a lot, thanks!
