How to manage the kernel modules on Linux

How do I edit my kernel command line

Decode a MP3 file

"under contruction"

Configure a static IP using the same private network range

"under construction" - Followed README file from ISEE - IGEP DSP - GST + DMAI Support Package 3.40.00

- Compiled gst-plugins-ugly using yocto tools

- rpm -igst-plugins-ugly-0.*.rpm

- rpm -i libmad0-0.*.rpm

- rpm -i gst-plugins-ugly-mad-0.*.rpm

- gst-launch filesrc location=sample.mp3 ! mad ! volume volume=0.25 ! alsasink

IGEP Firmware Yocto uses the following Ethernet network configuration (IP addresses)

• eth0 − 192.168.5.1
• eth0:0 − assigned via dhcp.

This Ethernet network configuration is really useful when you work using a Linux operating system like IGEP SDK Virtual Machine. Because you use eth0 device to communicate easily with your board and eth0:0 device to get Internet acces using dhcp protocol.

But some scenarios this network configuration is not useful, for example: if you use a non-Linux operating system, connect to two IP private range interfaces is not simple. This How-to can be useful to
