Hi!
We have a Dragonboard 410c. We chainload u-boot from little kernel (lk),
and from there the linux kernel obviously. All of it (not little kernel)
is build within yocto / Openembedded. It will generate a fitImage, that
we put into an ext4 partition, from there we bootm the stuff after
loading fitImage into RAM. This basically works, *but* small changes
(i.e. "random" changing a kernel config parameter, rebuild with slightly
other toolchain) will lead to a failed boot, meaning, that we get no
output whatsoever after
Starting kernel ...
Which puzzles me a lot, since I change only parameters, that should at
least make the Kernel print its first lines. I suspect, that something
goes wrong on initialization of the kernel.
I do not expect that anyone can reproduce and fix the bug for me, but
maybe, you can give me some hints how I can approach to debug this. I do
not have a hardware debugger, so it is pretty much printk debugging...
Thanks and Regards,
Matthias
