Intro
|
||
|
|
=====
|
||
|
|
|
||
|
|
The default configuration described below will allow you to start
|
||
|
|
experimenting with the buildroot environment for the SolidRun Clearfog GT-8K
|
||
|
|
based on the Marvell Armada 8040 SoC.
|
||
|
|
|
||
|
|
This default configuration will bring up the board and allow shell command
|
||
|
|
line access through the serial console.
|
||
|
|
|
||
|
|
How to build
|
||
|
|
============
|
||
|
|
|
||
|
|
$ make solidrun_clearfog_gt_8k_defconfig
|
||
|
|
$ make
|
||
|
|
|
||
|
|
How to write the SD card
|
||
|
|
========================
|
||
|
|
|
||
|
|
Once the build process is finished you will have an image file named
|
||
|
|
"sdcard.img" in the output/images/ directory.
|
||
|
|
|
||
|
|
Copy the bootable "sdcard.img" onto an SD card with "dd":
|
||
|
|
|
||
|
|
$ sudo dd if=output/images/sdcard.img of=/dev/sdX bs=1M conv=fsync
|
||
|
|
|
||
|
|
How to boot the board
|
||
|
|
=====================
|
||
|
|
|
||
|
|
The Clearfog GT-8K can be setup to load the bootloader from different sources
|
||
|
|
including eMMC, SPI flash, and SD-card.
|
||
|
|
|
||
|
|
To select boot from SD-card the DIP switches in SW6 (at the bottom of the
|
||
|
|
board) should be configured as follows:
|
||
|
|
|
||
|
|
SW6: 11010
|
||
|
|
|
||
|
|
Insert the micro SDcard in the Cleargfog GT-8K and power it up.
|
||
|
|
|
||
|
|
Serial console
|
||
|
|
==============
|
||
|
|
|
||
|
|
The serial console is accessible at the J27 pins header (TTL UART) with the
|
||
|
|
following pinout (pin #1 is marked with triangle on the PCB):
|
||
|
|
|
||
|
|
pin #1: Ground
|
||
|
|
pin #2: Armada 8040 Rx
|
||
|
|
pin #3: Armada 8040 Tx
|
||
|
|
|
||
|
|
Enable the switch (yellow) Ethernet ports
|
||
|
|
=========================================
|
||
|
|
|
||
|
|
To enable the Clearfog GT-8K internal switch port make sure to load the
|
||
|
|
'mv88e6xxx' kernel module, and up the switch up-link port (eth2 by default):
|
||
|
|
|
||
|
|
modprobe mv88e6xxx
|
||
|
|
ifconfig eth2 up
|
||
|
|
|
||
|
|
Then you can configure each switch port separately. These port are named
|
||
|
|
'lan1' to 'lan4' by default. 'lan1' is closest to the USB port, while 'lan4'
|
||
|
|
is closest to the blue Ethernet port.
