The USB boot made by moblin mic2 has two methods: liveos, direct boot, and traditional installation of Linux OS on the device. I want to install moblin2 on mid (menlow) and need to rebuild the kernel. You can use moblin-chroot to compile the kernel development environment or KVM.
Get the source code for the kernel from the moblin repo site, such as the wget htt
As mentioned in the previous article, the latest Android source code downloaded from the source code tree does not contain kernel code, that is, the android source code project does not contain Linux kernel code by default, instead, use the pre-compiled kernel, that is, the prebuilt/Android-arm/kernel-qemu file. So how

In general, the kernel and application have different address spaces on a multitasking system that uses virtual memory technology, so data exchange between the kernel and applications and between applications and applications requires specialized mechanisms for implementation, and it is well known that Inter-process

In uboot, the most common method to boot the kernel is the bootm command. The bootm command can boot the "uboot format" kernel. Let's take a moment to know what the kernel is in uboot

The kernel uses the physical page as the basic unit of memory management; the memory management unit (MMU) converts the virtual address to the physical
Address, usually in the unit of page processing. MMU manages the tables in the system in the unit of page size.
32-bit system: page size 4 kb
64-bit system: 8 KB page size
The kernel uses the corresponding data structure to represent each
I. kernel space
The kernel space is mapped by the kernel. It does not change with the process and is fixed.
Ii. High-end memory: The physical memory address exceeds MB, which we call high-end memory.
