Hello,
I am working on an embedded project with the u-boot and Minnowboard
max. With compressed kernel (bzImage) everything works fine, I want to
check the performance with
uncompressed kernel (vmlinux).
So for creating the image.fit file I followed the instructions as per
the file x86-fit-boot.txt except that I have changed the compression
to none in the image.its file since I want to check the uncompressed
Kernel
data = /incbin/("./vmlinux.bin");
type = "kernel";
arch = "x86";
os = "linux";
compression = "none";
The bootcmd is "bootcmd=fatload mmc 1:1 0x02000000 image.fit ; bootm
0x02000000". Now I am seeing that the
start up hangs after printing the commands starting kernel ... and the
time summary. Do you have any idea why it is happening?

I have seen in the document that it doesn't support for 64 bit kernel
and the document link given is now not accessible.
