Something about ARMLinux

One thing about ARMLinux-general Linux technology-Linux programming and kernel information. The following is a detailed description. Record what we learned about ARM development in the company for future reference:

1. Start and configure the file
Modify the startup and configuration files under/etc/init. d/rcS./tmp is currently readable and writable.

2. Install BSP
BSP is Board Support Package, according to ARM chip models to install, such as Motorola M9328MX1ADS/M9328MXLADS, the installation file is generally named: Linux-BSP-0-3-8.tgz, installed will generate the file system rt. cramfs for cropping. After installation, you can use arm-linux-gcc to debug the program, which is similar to gcc in linux.

3. Create disk imag
This is relatively difficult:
(1) Hold down the reset-> main menu-> select "1" on the ARM Development Board ";

(2) execute the following shell command:
#! /Bin/sh
Mkcramfs newdisk newroot. cramfs
Among them, newdisk is the place where the file system and its own programs are stored, and newroot. cramfs should be placed in windows.

(3) choose menu> 2 to start burn imag;
Use usb to transmit the root disk imag and place newroot. cramfs on RAM (Flash.

We can only remember that much, but we need to follow the chip step by step.
