Here's what each option and argument means:
mkimage: This is the command itself, which is used to create U-Boot bootable images.
-A arm: This option specifies the architecture of the target platform, which is "arm" in this case. It indicates that the kernel is intended to run on ARM architecture.
-O linux: This option specifies the operating system type, which is "linux" here. It tells mkimage that the kernel image is intended for Linux.
-T kernel: This option specifies the type of data being processed as a "kernel." It informs mkimage that the input file is a kernel image.
-C none: This option specifies that no compression should be applied to the input data. In this case, "none" means the kernel image is not compressed. This is important because some kernel images might be compressed, but in this command, it's specified as uncompressed.
-a 0x80008000: This option sets the load address for the kernel image. The address 0x80008000 is where the kernel will be loaded in memory.
-e 0x80008000: This option sets the entry point address for the kernel image. The entry point is where execution should begin after the kernel is loaded. It's also set to 0x80008000 in this case, which means the kernel will start executing from this address.
-n "Linux Kernel": This option sets the image name to "Linux Kernel." This is a human-readable identifier for the image.
-d arch/arm/boot/zImage: This specifies the input file, which is the kernel image you want to package into a U-Boot bootable image. The path provided is the location of the kernel image file on your system. Make sure this path is correct and that the file exists.
uImage: This is the output file name. It's the name of the U-Boot bootable image that mkimage will create.
In summary, this mkimage command is used to create a U-Boot bootable image for an ARM-based Linux kernel. It specifies various parameters such as architecture, operating system type, load address, entry point, image name, and the input kernel image file. The resulting output file will be named "uImage" and will be suitable for loading and executing the Linux kernel using U-Boot on an ARM platform. User for odroid machines -a 0x0 -e 0x0
