JZ2440 Development Notes (4) - Setting Static IP-EEWORLD

Collect

1. Configure a static IP address

$sudo vim /etc/network/interfaces

The original content only has the following two lines:

auto lo

iface lo inet loopback

Append the following to the end:

auto eth0

iface eth0 inet static

address 192.168.1.33

gateway 192.168.1.1

netmask 255.255.255.0

network 192.168.1.0

broadcast 192.168..255

Then save and exit;

2. Manually configure dns (this file is a dynamic DNS and will be restored to default after restart)

$sudo vim /etc/resolv.conf

I want to add the following to the end:

nameserver 192.168.1.1

Then save and exit.

3. Restart the network to make the changes take effect

$sudo /etc/init.d/networking restart

There is a problem here. After restarting Ubuntu, I found that I could not access the Internet again. The problem lies in /etc/resolv.conf. After restarting, the DNS configured in this file is automatically changed to the default value. So it is necessary to permanently modify the DNS. The method is as follows:

Method 1: Add dns-nameservers 8.8.8.8 to /etc/network/interfaces

Method 2: /etc/resolvconf/resolv.conf.d/base insert nameserver 8.8.8.8 nameserver 8.8.4.4

Save resolvconf -u View cat /etc/resolv.conf

vim /etc/resolvconf/resolv.conf.d/base

cd /etc/resolvconf/resolv.conf.d/

# cat base

nameserver 192.168.0.1

nameserver 8.8.8.8

nameserver 8.8.4.4

JZ2440 Memory Interface

Three types of interfaces 1. GPIO / Gate Circuit 2. Protocol interface: UART, I2C, I2S, SPI Memory Controller CPU --- addr --- memory controller --- select different modules according to addr --- data-- module The CPU gives the address to the memory controller, and the memory controller will get the corresponding ad
