openssh-server minicom picocom tftp tftpd gettext libncurses5 libncurses5dev unzip quilt git git-doc git-gui
Get latest sources
git clone https://github.com/8devices/carambola carambola cd carambola
Get older revision
For some reason you might wish to get older source revision. To see available tags execute these commands:
git tag -l
You should see something like this
carambola/v1.0 carambola/v1.1 carambola/v1.1-rc1 carambola/v2.0
carambola/v2.0-rc1 carambola/v2.1 carambola/v2.1-rc1 carambola/v2.1-rc2
carambola/v2.2-rc1 carambola/v2.3-rc1
In order to get older version, type this command (but this should be rare case)
git checkout carambola/v1.0
Stable version
At this point (2012-11-11) stable version is carambola/v2.3-rc4. To get this version type command:
git checkout carambola/v2.3-rc4

Type
./scripts/feeds update -a ./scripts/feeds install -a
I suppose you would also like to add luci.
Build image
If you wish you can change kernel settings, but at this time skip this step.
make kernel_menuconfig
Type
make menuconfig
You should see configuration window like this:
Let's leave everything untouched for now and and exit.
Type
make
for standard building procedure or
make -j 2
if you want to use more than 1 thread and you have more than 1 CPU core on your system. This process takes
long time (it took ~1 hour on 4 core machine) or
make V=99
if you need or want to see more details.
You should see build log like this:
Or if you feel really advanced, you can get email notification upon completing build proces. For this you need to
install and configure email client. After you are done, type this long command:
date > /tmp/text.txt; make -j 2 >> /tmp/text.txt; date >> /tmp/text.txt;
mail -s "done" email_where_to_send_report@server.com < /tmp/text.txt
If you wish to observe current progress on computer, type in another console
tail -f /tmp/text.txt
Connect using serial cable
RS‐232 level
It is best to connect to carambola using standard RS-232 male cable. Just plug cable to carambola, set 115200
8N1 settings without hardware flow control and power up your carambola.
TTL 3.3V level
However, if you have TTL level USB to serial converter, you should do some soldering.
Remove J9 and J10 jumpers and connect FTDI 3.3V TTL serial to USB cable. J9.1 – RX(input), J10.1 –
TX(output). I used FTDI 3.3V USB to serial converter.
Software
You can use any terminal program you wish to communicate.
Start terminal
Connection settings
•
115200 8N1, no hardware flow control.
Windows
I recommend using V-term32 (no need to install just unzip and run) or TeraTerm program.
Linux minicom
TODO
Linux picocom
picocom -f n -p n -b 115200 -i -r -l /dev/ttyUSB0
picocom -b 9600 /dev/ttyUSB0
•
Picocom man
•
To exit, press and hold CTRL, A, Q.
Other Linux uart settings and useful commands
If you do not have installed stty you should get it by typing
opkg install coreutils-stty
To set options:
stty -F /dev/ttyUSB0 cs8 9600 ignbrk -brkint -icrnl -imaxbel -opost -onlcr
-isig -icanon -iexten -echo -echoe -echok -echoctl -echoke noflsh -ixon crtscts
To get options:
stty -a -F /dev/ttyUSB0
To read from device
tail -f /dev/ttyUSB0
Set up
p TFTP se
erver
Windows
You can set up TFTP server
very quuickly using TFTP32
sofwaare. It is free.
Enable TFTP
server. Your
settings should
look like:
Linux
If you wish, you can use linux machine to do the same task.
sudo apt-get install xinetd tftpd tftp
sudo touch /etc/xinetd.d/tftp
sudo nano /etc/xinetd.d/tftp
Paste this code:
service tftp { protocol = udp port = 69 socket_type = dgram wait = yes
user = nobody server = /usr/sbin/in.tftpd server_args = /home/tftpboot
disable = no }
sudo mkdir /home/tftpboot
sudo chmod -R 777 /home/tftpboot
sudo chown -R nobody /home/tftpboot
sudo service xinetd restart
Upload new firmware to Carambola 2
This topic covers few methods how to upgrade firmware on Carambola. Some methods require only serial
connection, some only LAN, some LAN and Serial. Also you might need to install/setup other software to
perform these tasks.
sysupgrade
sysupgrade is best ever way to upgrade firmware. For this to work you must be connected to Carambola
terminal. It does not matter using Serial, LAN ir Wireless connection.
mtd
mtd method is similar to sysupgrade. Use any one you like.
Serial connection only
Using serial cable is most dangerous one. There many things that can go wrong. Ensure you have good serial
cable (cheaper usb-serial adapters don't work), rock solid power supply and steel nerves :)
TFTP
TFTP method to upgrade firmware requires you serial connection to Carambola and configured TFTP server
over LAN. Wireless connection does not work.
Upgrading bootloader
If for some reason you have older bootloader and wish to upgrade, you must proceed here. It is even more
dangerous than upgrading firmware using serial connection only. If something fails, there are big chances you
render your module useless.
Web interface / LUCI
This method is recommended for novices. Connect Carambola web interface, browse for firmware upgrade,
select file and press upgrade.
