[U-Boot-Users] about use mkimage to create uImage?

[zhuzhenhua]

if i mkimage without compressing, kernel can run correct, the command
is as follow
./tools/mkimage -A arm -O linux -T kernel -C none-a 0x30000000
-e0x30008000 -n "Linux" -d vmlinux  uImage


but i want to create a compressed uImage,i use commands like these,it
stop at "starting kernel..."
arm-linux-objcopy -O binary -R.note -R.comment -S vmlinux linux.bin
gzip -9 linux.bin
./tools/mkimage -A arm -O linux -T kernel -C gzip -a 0x30008000
-e0x30008000 -n "Linux" -d linux.bin.gz  uImage

i think the second method should run well,and i see the same example
in the Readme of u-boot src.

any hints are appreciate.

without compressing, you used "-a 0x30000000" and with compressing, you
used "-a 0x30008000".

It probably fails because you changed the load address...

something strange happened. as i said, i had used command

'./tools/mkimage -A arm -O linux -T kernel -C none-a 0x30000000
-e0x30008000 -n "Linux" -d vmlinux  uImage'
to get a runing correctly uImage.
but today i use the same command to the same vmlinux to generate the
uImage which runing only to "starting kernel........." and then stop.

but if i download the uImage i made few days ago, it still can run correct
what's happen? or maybe i rember the wrong command ?i just got confused.

thanks for any hints or answers

Best regards
