Hi,
I make a linux uImage with command "make uImage" ,
and linux kernel can start up after downloading it into the
target board, but now I want to generate uImage by vmlinux
with mkimage, not by "make uImage",so I do it as follows:
1)arm-none-linux-gnueabi-objcopy -O binary -R .note -R .comment \
-S /home/linux-2.6.12/vmlinux /home/temp/vmlinux.bin
2)gzip -9 /home/temp/vmlinux.bin
3)mkimage -A arm -O linux -T kernel -C none \
-a 00008000 -e 00008000 \
-n 'Linux-2.6.12.6-arm1' -d /home/temp/vmlinux.bin.gz /home/temp/uImage
At last, I load uImage to ram to run, but the following message happens:
Marvell>> tftp 0x400000 uImage

you compressed the "vmlinux.bin" file here, but didn't specify the
compression type later by the "-C" option of "mkimage".

please try it again with "-C gzip" option.

The image header describes the image as uncompressed, but really
it isn't. Uncompressed code can't be executed.

the last sentence should be "Compressed code can't be executed." of
course. Sory for that.
