*********************
|
|
|
|
The 'ci20_defconfig' will create a root filesystem and a kernel image
|
|
under the 'output/images/' directory. 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. Here you
|
|
have the instructions to set the ip address, netmask and gateway:
|
|
|
|
setenv ipaddr x.x.x.x
|
|
setenv netmask x.x.x.x
|
|
setenv gatewayip x.x.x.x
|
|
|
|
Now you have to set the ip for the TFTP server you are going to load the
|
|
kernel image from, and also the name of the kernel image file (we use
|
|
'uImage' as a filename in this example):
|
|
|
|
setenv serverip x.x.x.x
|
|
setenv bootfile uImage
|
|
|
|
And finally load the kernel image:
|
|
|
|
tftpboot
|
|
|
|
Now you have to extract the generated root filesystem into a USB drive
|
|
or SD-Card. Here you have the instructions to boot from the two of them.
|
|
You have to choose the one your prefer:
|
|
|
|
From USB
|
|
setenv bootargs console=ttyS4,115200 console=tty0 mem=256M@0x0
|
|
mem=768M@0x30000000 root=/dev/sda1
|
|
|
|
From SD-Card
|
|
setenv bootargs console=ttyS4,115200 console=tty0 mem=256M@0x0
|
|
mem=768M@0x30000000 root=/dev/mmcblk0p1
|
|
|
|
And finally run this command to boot the board:
|
|
bootm
|
