When I build a bundled kernel image I have a normal bzImage (~10mb) and
a bzImage-initramfs(~30mb) in my build directory. Check the kernel image
on your device, for me always the unbundled one gets deployed with the
image, so I copy the bundled image via "scp. You may have to increase
size of the boot partition in case you use an additional boot partition.
In wic you can use the --size <size in mb> command.

I didn't ask the original question but have the same problem. I have the
thud branch checked out, but I couldn't find that fix on google. Can you
elaborate on this ?
