+wget https://github.com/hardkernel/u-boot/raw/odroidxu3-v2012.07/sd_fuse/hardkernel_1mb_uboot/tzsw.bin.hardkernel
+```
+
+You also need `u-boot-mmc.bin` that is inside `tizen-unified_20180425.2_tv-boot-armv7l-odroidxu3.tar.gz` file.
+```
+tar xvf tizen-unified_20180425.2_tv-boot-armv7l-odroidxu3.tar.gz u-boot-mmc.bin
+```
+
+
+## Flashing script
+
+Download `sd_fusing_xu4-u1604.sh` from https://github.sec.samsung.net/RS7-RuntimeNTools/TizenTools/tree/master/sd_fusing_xu4
+
+This file is modified to work on Ubuntu 16.04.
+
+You can download original (What I got in the first place) file as `sd_fusing_xu4.sh`
+
+Make it executable
+```
+chmod u+x sd_fusing_xu4-u1604.sh
+```

+
+# Flash
+
+Host environment
+- Ubuntu 16.04
+- microSD connected through USB Reader as `/dev/sdd` file.
+
+## Flash boot files
+
+Give `--format` if it's a new flash memory.
+```
+sudo ./sd_fusing_xu4-u1604.sh --format \
+-d /dev/sdd \
+-b bl1.bin.hardkernel bl2.bin.hardkernel.1mb_uboot tzsw.bin.hardkernel u-boot-mmc.bin
+```
+Change `/dev/sdd` to your configuration.
+
+You will be asked to confirm format when used `--format`. Please type `y` to continue.
+```
+/dev/sdd will be formatted, Is it OK? [y/n]
+y
+```
+
+You can omit `--format` from the second time and followings.
+```
+sudo ./sd_fusing_xu4-u1604.sh \
+-d /dev/sdd \
+-b bl1.bin.hardkernel bl2.bin.hardkernel.1mb_uboot tzsw.bin.hardkernel u-boot-mmc.bin
+```
+`--format` option will, 1) delete current partition 2) create new partition table, 3) format each partitions.
+
+- If you meet `./sd_fusing_xu4-u1604.sh: line 147: pv: command not found` message and want to remove this message, install pv package by `sudo apt-get install pv`
+
+## Flash image files
+```
+sudo ./sd_fusing_xu4-u1604.sh -d /dev/sdd \
+-b tizen-unified_20180425.2_tv-boot-armv7l-odroidxu3.tar.gz \
+tizen-unified_20180425.2_tv-wayland-armv7l-odroidu3.tar.gz
+```
+
+# Boot with Tizen 4.0
+
+Follow the steps
+
+Step 1.
+- Take out eMMC memory card if you have any
+
+Step 2. 
+- Plug-In microSD with Tizen 4.0
+
+Step 3. Set boot switch
+- Refer https://wiki.odroid.com/odroid-xu4/hardware/hardware
+- Set `Boot mode selector` switch on the bottom of the board to `uSD`
+
+Step 4. Connect Serial Console port with USB of Host computer
+- Install `minicom`
+```
+sudo apt-get install minicom
+```
+- Add yourself to the group `dialout`
+   - `sudo vi /etc/group`
+- Use serial terminal program like `minicom` (note that `/dev/ttyUSB1` might be different in your environment.)
+```
+minicom --baudrate 115200 --device /dev/ttyUSB1
+```
+- Use `CTRL-a z o` > `Serial port setup` to enter the dialog
+- Baud should be `115200-8N1`
+- Set configuration `Hardware Flow Control` to `No` to enable communication(keyboard typing..)
+- `Save setup as dfl` in configuration
+- If you are connecting from Windows or Mac my need to install the driver
+   - https://www.silabs.com/products/development-tools/software/usb-to-uart-bridge-vcp-drivers
+   - Use `PuTTY` for Windows.
+
+Step 5. Connect Power
+- You should see the boot logs...
+
+Step 6. Login root
+- login `root` pwd `tizen`
+
+# After boot
+
+## Slow down the fan speed
+
+If the fan noise is disturbing, you can slow down a little.
+
+```
+echo "100" > /sys/devices/platform/pwm-fan/hwmon/hwmon0/pwm1
+```
+This will slow down the speed to 100. Range is from 0 to 255. "0" to make it stop. "255" for maximum speed.
+
+This value resets after reboot so may have to set the value every time you reboot.
+
+## Expand root file system
+
+Default Root FS is 3G but the size shows about the size of the image file, about 700MB.
+
+There would be not enough space to install files. To overcome this do the following in Tizen root shell.
+
+```
+mount -o remount,rw /
+resize2fs /dev/mmcblk0p2
+sync
+```
+And reboot
+```
+reboot
+```
+
+`df` before and after
+```
+Filesystem           1K-blocks      Used Available Use% Mounted on
+/dev/root               754716    721228      8764  99% /
+```
+to
+```
+Filesystem           1K-blocks      Used Available Use% Mounted on
+/dev/root              3031952    724724   2282504  25% /
+```
+
+
+## Wide console
+
+```
+stty cols 200
+```
+
+## Setting IP Address of Target Device
+
+Use `connmanctl`
+
+**CAUTION** PLEASE DO THIS IN YOUR TARGET DEVICE. RUNNING THIS IN YOUR HOST MAY DAMAGE.
+
+Step 1. Get the service name
+- You first need to connect Ethernet cable.
+```
+connmanctl services
+```
+Will drop something like this
+```
+*AR Wired                ethernet_1a43230d5dfa_cable
+```
+
+Step 2. Use `config` to set the IP address
+```
+connmanctl config ethernet_1a43230d5dfa_cable --ipv4 manual 10.113.XXX.YYY 255.255.255.0 10.113.XXX.1
+connmanctl config ethernet_1a43230d5dfa_cable --nameservers 10.32.192.11 10.32.193.11
+```
+where `XXX.YYY` is your address for the target board.
+
+Setting for proxy can be done with connmanctl but don't know how to check.
+```
+connmanctl config ethernet_1a43230d5dfa_cable --proxy manual http://10.112.1.184:8080/
+```
+You can use environment variable but still don't know how to check.
+
+
+This information remains after reboot.
+
+# Connecting with SDB
+
+Default Tizen image has running SDBD in the device with default port (26101).
+
+In your Linux or Windows with `sdb` command,
+```
+sdb connect 10.113.XXX.YYY
+```
+Result will be something like
+```
+* Server is not running. Start it now on port 26099 *
+* Server has started successfully *
+connecting to 10.113.xxx.yyy:26101 ...
+connected to 10.113.xxx.yyy:26101
+```
+With `sdb devices`,
+```
+sdb devices
+List of devices attached 
+10.113.xxx.yyy:26101  	device    	xu3
+```
+It comes up with `xu3` as our `xu4` also uses same image `xu3` image.
+
+
+# Known issue
+- `ls -al` of root folder shows strange output.
