Hi Jerry!
I have tried that, but after have used 6000 bytes padding of 3900
bytes code i don't think that is the solution.
and at the example above the fdt is 22219 bytes (19000 padding) = 0x56CB
and then the totalsize is changed to 4096 = 0x1000 which give an end
of the fdt to 007fb000 and the comparing is false when the "real end"
is 007faff2 + 10 = 007fb002
So what is going wrong?
