KERNEL_IMAGETYPE="uImage" not working

Embedded Devices Linux

Hi,
I have ccimx6ulsbc dev board with dey-2.2r3

I know that DIGI only supports zImage. I am not sure there is any way that uImage can be generated at least. I tried by setting KERNEL_IMAGETYPE=“uImage”, but it’s not taking. There is a file Image under arch/arm/boot folder, I am not sure can be used to convert it into uImage, or is there any way using mkimage to convert zImage into uImage. It seems always compressed even with -C none switch for the mkimage cmd.

I don’t whole thing to work for the uImage. But it would be nice if I can have uImage (zImage uncompressed) besides the zImage file.

Thank you,

david Zhou

try:

sudo apt-get install u-boot-tools

mkimage -A arm -O linux -T kernel -C none -a 0x80008000 -e 0x80008000 -n “Linux kernel” -d arch/arm/boot/zImage uImage
The mkimage utility comes with the u-boot-tools package in Ubuntu (if that’s what you’re using), and it can be installed with the command sudo apt-get install u-boot-tools

Why do you need to build uImage?
