QUESTIONS1. I have built a vmlinux image but I can boot it.2: The mkimage tool, ARMboot's tftp command, and the bootm command require   certain load and entry addresses. I'm confused which ones to chose.ANSWERS1. I have built a vmlinux image but I can boot it.--------------------------------------------------ARMboot is designed to boot Images as created by the mkimage tool, thatcomes with ARMboot and is automatically built, too. You cannot directly loadthe vmlinux image, as it expects a number of prerequisits such as specialregister contents etc.2. The mkimage tool, ARMboot's tftp command, and the bootm command require   certain load and entry addresses. I'm confused which ones to chose.--------------------------------------------------------------------------Well, there are 3 different addresses:1. Kernel Load Address. This is the address, where the kernel was linked   to when you built the vmlinux and can be found in arch/arm/Makefile.   The default for it is:      ifeq ($(CONFIG_CPU_32),y)   PROCESSOR    = armv   TEXTADDR     = 0xC0008000   LDSCRIPT     = arch/arm/vmlinux-armv.lds.in   endif      Provide this as "-a" parameter to mkimage.2. Kernel Entry Point. This is the address, where ARMboot jumps to to   enter the Kernel. It usually is the same as the kernel load address.   Provide this as "-e" parameter to mkimage.3. The Network Download Address. This is where you download the mkimage   File. This address MUST BE different to the Kernel Load Address, and   should be sufficiently far away to allow ARMboot to relocate the    image to the final Kernel Load Address. Loading to the 5th MB   within the RAM is usually a good idea, eg. if the RAM begins at   0xc0000000, you can do this:      LART # tftp c0400000 linux.img   ARP broadcast 1   eth addr: 00:02:03:04:05:06   TFTP from server 192.168.1.1; our IP address is 192.168.1.2   Filename 'image.img'.
