Thanks. If it is appended to the zImage wrapper, then things should be
fine (this is the expected way to do when not passed in from the
bootloader). If a *.dtb.o target has been used to embedded it into the
kernel-proper (vmlinux) then you will have a problem. The *.dtb.S
target puts the dtb data into the dtb.init.rodata section which gets
discarded.

Hi Grant,<br>
<br>
you're right that's exactly what nios2 is doing... <br>
I guess we could modify the section where it gets loaded but that
sounds to me a bit like a hack... What is the best target to look at
for a clean, similar solution? Arm with

CONFIG_ARM_APPENDED_DTB?<br>
