I think you should modify the bootargs on your dts.
--
chosen {
bootargs = console=ttyS0 root=/dev/ram;
linux,stdout-path = /p...@0/ser...@83e0;
} ;
Thanks, that worked great, I now have a fully bootable not only kernel, but
full OS

Looks you means the TLB exception handler should be same between the native

Yes.
Please use simpleImage.your target dts name.elf.
Great, that seems to be it...
Except that nothing happens when I jump to 0x4, no message from the

That depends on what bootloader we're talking about -- I don't know
what the original poster's custom loader can do.

Why? That's pretty much what the bootwrapper does. Our hypervisor has

In the past I've been using the PPC architecture to generate elf kernels (I

zImage.elf: ELF 32-bit MSB executable, PowerPC or cisco 4500, version 1
(SYSV), statically linked, not stripped

Which bootloader? Looks you want to run it as XIP.
I have my own downloader which does a few things and then transfers the kernel
from a flash to the memory and then simply jumps to the 1st address with a
0x4() C function call.
But I need to first use Xilinx tools to transfer the kernel
