Official method¶
First installation boot¶
- Start application used for serial port communication, eg.
minitermorminicom.
Informacja
PandaBoard provides communication over serial port. Port baud speed is 115200bps.
- Connect PandaBoard to PC with serial port.
- Turn on PandaBoard.
First system loading will cause that the system partition will be expanded to the size of memory card. That process cannot be interrupted. You need to wait till the moment when one of LEDs will blink.
For the first time configuration wizard will be started. Instructions will be displayed on the console.

Informacja
To have correctly working wireless network it is required to have MAC address manually set.
Ostrzeżenie
Be aware that network addressing settings have been changed in last step due to fact that the same network cannot be used on both interfaces.
Informacja
Above configuration is used in wireless network robolab which is in laboratory. Current preshared key for wireless network is published in laboratory. IP addresses are connected with MAC addresses. In laboratory used MAC prefix is de:ad:be:ef:00:**. Last two characters decide which IP address will be assigned. Following scheme is used:
de:ad:be:ef:00:00 - 192.168.2.200

Updating system¶
Ostrzeżenie
It is available updating to Ubuntu 14.04.1 LTS using command do-release-upgrade. Due to issues with modules for devices Ninedof and Roboclaw it is not recommended. Following steps could skipped and you can jump to step related to updating packages.
Informacja
Update process executed by command do-release-upgrade can take few minutes. Using screen prevents situation that command execution will be interrupted and allows detaching from console/session with keys [Ctrl]+[a] and [d]. Reconnecting can be done by executing command screen -r.
Ostrzeżenie
Please monitor updating process. During updating there will be several questions. When updating process will finish system need to be rebooted. Reboot need to be confirmed.

Packages which are used by PandaBoard are published in the repository http://ports.ubuntu.com/pool/main/l/linux-ti-omap4/.
After update done by tool do-release-upgrade system does not support wireless network. You need add omap repository to repositories. After this, update packages list need to be done and following packages need to be installed:
aptitude install -y software-properties-common
add-apt-repository ppa:tiomap-dev/release
aptitude update
touch /boot/initrd.img-3.13.0-37-generic
aptitude install linux-headers-omap linux-image-omap linux-omap
Ostrzeżenie
Kernel installation requires files in directory /boot/. When some files are missing, please create them using command touch.
- Execute
reboot.
Updating packages¶
Recommended is to turn off installing recommended packages in aptitude:
- Start
aptitude - Use keys
[Ctrl]+[t] - Go to menu
Options→Preferences - Disable option
Install recommended packages automatically - Close aptitude using keys
[Ctrl]+[q] - Perform update i install additional packages:

- Add to file
/etc/rc.locallineiw reg set PL. - Shutdown system using command
sudo poweroff.
Updating bootloader¶
To have card combatible with board in version B3, you need download latest bootloader version u-boot and manually compile it as per following instruction. To execute following commands additional software need to be installed:
- make
- g++
- gcc
- u-boot-tools
- g++-arm-linux-gnueabihf
- gcc-arm-linux-gnueabihf
- binutils-arm-linux-gnueabihf
Command to execute: apt-get install make g++ gcc u-boot-tools g++-arm-linux-gnueabihf gcc-arm-linux-gnueabihf binutils-arm-linux-gnueabihf.
For some distributions version need to be changed. For Debian, current testing version has listed packages.
