than using slots like a PC.2) Guide. The difference between the bootloader is determined by the hardware architecture. Embedded Linux mostly uses uboot booting, and Linux on PCs usually uses grub.3) kernel and driver. This is also the reason for the different hardware architectures. Devices on x86 typically use a variety of buses to minimize differences between

, the compiler runs as a/usr/local/arm/arm-2009q3,busybox compiled binary 11 dynamic-link library, so you need to copy the library files from the compiler to the Lib directory, using the command"cp/usr/local/arm/arm-2009q3/arm-none-linux-gnueabi/libc/lib/*./" Copy.After the library file copy is complete, return to the System/var directory and build the Lib,lock,log,run,tmp five directory under the Var directory. At this point, the files required by th

1. Preparations First, install the GCC tool chain and the development environment. You can check the previous steps. You have to compile the kernel. Generally, the Development Board has the kernel. Now I do not know how to configure the kernel. You can only compile the kernel according to the default settings of the Development Board. uboot needs to be compiled before compilation, it is recommended that new users like me learn to write drivers first and learn Kernel configuration pruning slowly.
