On this page you will learn how to move the default RS-232 console to Ethernet. This might be useful in systems where you want to use the RS-232 port for something else or if you want a remote console.

U-Boot

• modify the config header file for your board and add it:

#define CONFIG_NETCONSOLE 1

• recompile and reflash your U-Boot:

$ make uboot-rebuild

• redefine some environment variables (here 192.168.1.2 is the IP address of my Host PC):

BIOS> setenv ncip 192.168.1.2
BIOS> setenv stdin nc; setenv stdout nc; setenv stderr nc

Linux

• You have to use netconsole script from U-Boot sources (default port is 6666):

$ tools/netconsole <ip> [port]
