This document will try to explain how +to use them in order to run Buildroot in the MIPS Creator CI20 board. + +Assuming you are at the U-Boot prompt of the MIPS Creator CI20, you have to +load the generated kernel image by using the 'tftpboot' command. In +order to do that, you will need to get the network working.
