#define CONFIG_NETCONSOLE 1

$ 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):
