- SD Image and instruction to burn the image to microSD card; like
sudo umount /dev/sdc5 sudo dd bs=4M if=~/Downloads/udoo_dual_ubuntu1204_v2.0.img of=/dev/sdc sudo sync df -h # find out <sd_label> in /media/<sd_label> sudo umount /media/<sd_label>
Create microSD from image
http://www.udoo.org/getting-started/creating-a-bootable-micro-sd-card-from-image/
Create microSD from binaries
We first download the binaries from http://www.udoo.org/downloads/#tab2. Then we follow the instruction in http://elinux.org/UDOO#Creating_a_bootable_Micro_SD_card_from_binaries to create the microSD card. This method works for Debian, Ubuntu, Linaro OS.
Back up/Save to microSD card
Suppose my microSD card is on /dev/sdc.
sudo dd bs=1M if=/dev/sdc of=~/Udoo-backup.bin sudo dd bs=1M if=~/Udoo-backup.bin of=/dev/sdc

UDOObuntu
For some reason, the system freezes about 25 minutes (shown on htop screen).
Android 4.3 Jelly Bean
Debian Wheezy armHF
Arduino Programming

From Udoo itself
I can use dmesg | grep ttymxc3 to double check the device is attached.
Use sudo ln -sf /dev/ttymxc3 /dev/ttyS0 each time we boot the Ubuntu (or add it to the local.rc file to ensure it occurs on each boot) . See the forum discussion.
Simple LED sketch works well.
The Ethernet webServer sketch does not work. Why?
On an External computer
First I unplug J18 jumper, remove microSD card, and connect microUSB to CN6 in UDOO.
Download the official Arduino IDE 1.5.4.
I try to use dmesg | grep cp210x to check the device. The obstacle is the device is not found in Arduino IDE (No device found on ttyUSB0). If I try to follow 'Serial Driver' part to download and run 'make' , I will get an error
Linux_3.x.x_VCP_Driver_Source/cp210x.c:164:12: Error: 'usb_serial_probe' undeclared here (not in a function) Linux_3.x.x_VCP_Driver_Source/cp210x.c:165:16: Error : 'usb_serial_disconnect' undeclared here (not in a function)
Serial port monitor
On Linux, I can use minicom program to monitor serial port. We can install it by using 'sudo apt-get install minicom'.
Use sudo minicom -s to configure minicom first. Make sure the serial port is correct. For example, use /dev/ttyS0 when we use UDOO and dev/ttyUSB0 when we use external PC. The baud rate is set to 9600 8N1 and that 'Hardware flow control' is set to 'no'. Once we are done with the settings, use 'Save setup as dfl' and minicom will start up with the correct settings next time.
We shall not launch minicom immediately. We shall let Arduino IDE to finish uploading a sketch and then we can launch minicom. We can quit minicom by using Ctrl+A and z and x. If we start minicom before Arduino IDE finishes uploading a sketch, Arduino IDE will not be able to upload successfully; it will show an error 'no device found on /dev/ttyS0'.

Install Gapps in Android
- http://www.udoo.org/guide-how-to-install-gapps-on-udoo-running-android/
- [http://www.teamandroid.com/gapps/ (find a matched gapps from a android version). The file <gapps-jb-20130812-signed.zip> works for jelly bean version (v4.3 and 4.2).

The real sdcX number can be found by using 'df -h' command (my computer already has 2 hard disks, so a USB drive goes to /dev/sdc).
sudo umount /dev/sdc* # Unpack the zip in a local temp directory. mkdir gapps sudo unzip gapps-jb-20130812-signed.zip -d gapps cd gapps sudo mkdir /mnt/sdc5 df -h # find /media/brb/data1 partition # Mount partition 5 sudo mount /dev/sdc5 /mnt/sdc5 # See what's in /mnt/sdc5 before the operation (optional) $ ls /mnt/sdc5 anr app-lib dalvik-cache drm media resource-cache user app app-private data local misc ssh app-asec backup dontpanic lost+found property system # Rsync everything from the “system” folder in the zip file to the mounted partition. sudo rsync -avu system/* /mnt/sdc5/ # See what's in /mnt/sdc5 after the operation (optional) $ ls /mnt/sdc5 addon.d app-lib data framework media ssh usr anr app-private dontpanic lib misc system app backup drm local property tts app-asec dalvik-cache etc lost+found resource-cache user brb@brb-P45T-A:~/Downloads/gapps$ # Unmount SD, put it in the UDOO, and voilà, sudo umount /mnt/sdc5

This tutorial teaches how to add tightvncserver to rc.local file so it is available on booting.
# Install tightvncserver sudo apt-get install tightvncserver sudo nano /etc/rc.local # Add the following line before 'exit 0' line. vncserver :1 -geometry 800x600 -depth 24
