This patch is intended only handle Image.gz which is a compressed version of kernel "Image" file. That's why relevant code is only added to booti command. > When you say the > compressed file, you do mean the Image.gz (for example) itself, > right?

I will change the kernel_gz_size to filesize. -- Regards, Atish _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de https://lists.denx.de/listinfo/u-boot
