1Intro
2=====
3
4The default configuration described below will allow you to start
5experimenting with the buildroot environment for the SolidRun Clearfog GT-8K
6based on the Marvell Armada 8040 SoC.
7
8This default configuration will bring up the board and allow shell command
9line access through the serial console.
10
11How to build
12============
13
14 $ make solidrun_clearfog_gt_8k_defconfig
15 $ make
16
17How to write the SD card
18========================
19
20Once the build process is finished you will have an image file named
21"sdcard.img" in the output/images/ directory.
22
23Copy the bootable "sdcard.img" onto an SD card with "dd":
24
25 $ sudo dd if=output/images/sdcard.img of=/dev/sdX bs=1M conv=fsync
26
27How to boot the board
28=====================
29
30The Clearfog GT-8K can be setup to load the bootloader from different sources
31including eMMC, SPI flash, and SD-card.
32
33To select boot from SD-card the DIP switches in SW6 (at the bottom of the
34board) should be configured as follows:
35
36 SW6: 11010
37
38Insert the micro SDcard in the Cleargfog GT-8K and power it up.
39
40Serial console
41==============
42
43The serial console is accessible at the J27 pins header (TTL UART) with the
44following pinout (pin #1 is marked with triangle on the PCB):
45
46 pin #1: Ground
47 pin #2: Armada 8040 Rx
48 pin #3: Armada 8040 Tx
49
50Enable the switch (yellow) Ethernet ports
51=========================================
52
53To enable the Clearfog GT-8K internal switch port make sure to load the
54'mv88e6xxx' kernel module, and up the switch up-link port (eth2 by default):
55
56 modprobe mv88e6xxx
57 ifconfig eth2 up
58
59Then you can configure each switch port separately. These port are named
60'lan1' to 'lan4' by default. 'lan1' is closest to the USB port, while 'lan4'
61is closest to the blue Ethernet port.
