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

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
