That's why I thought also but I tried to move the DT at end of DDR
0x1E00 and at the middle 0x1000 but same issue.
And maybe I'm wrong but if I remember correctly as my Kernel is also
build with the ATAG parameters fallback and I have the earlyprintk
enabled the error should be something like this :
# Starting kernel ...
# Uncompressing Linux... done, booting the kernel.
# Error: unrecognized/unsupported machine ID (r1 = ???).
(This is an issue I have already encountered with a previous board
here https://lists.denx.de/pipermail/u-boot/2018-February/321031.html)
I tried also to load the kernel @1000 and DT @1800 but still
stuck at "Starting kernel ..."
I will try to boot a more recent kernel and see if this still happen.
Thanks,
Clement
