+
+Host environment
+- Ubuntu 16.04
+- microSD connected through USB Reader as `/dev/sdd` file.
+
+## Flash boot files and image files
+
+Give `--format` if it's a new flash memory.
+```
+sudo ./sd_fusing_xu4.sh --format \
+-d /dev/sdd \
+-b bl1.bin.hardkernel bl2.bin.hardkernel.1mb_uboot tzsw.bin.hardkernel \

+tizen-unified_20191105.1_tv-wayland-armv7l-odroidxu3.tar.gz
+```
+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.sh \

+```
+`--format` option will, 1) delete current partition 2) create new partition table, 3) format each partitions.
+
+- If you meet `./sd_fusing_xu4.sh: line 147: pv: command not found` message and want to remove this message, install pv package by `sudo apt-get install pv`
+
+# Boot with Tizen
+
+Follow the steps
+
+Step 1.
+- Take out eMMC memory card if you have any
+
+Step 2.
+- Plug-In microSD with Tizen
+
+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 automatically and after reboot so may have to set the value every time you reboot and when fan noise loud again.
+
+Other solution is changing cpu governors policy for big core to `ondemand`
+
+```
+echo ondemand | tee /sys/devices/system/cpu/cpu{0..7}/cpufreq/scaling_governor
+```
+
+## Remount root file system writable
+
+Default ROOT FS (except `/opt/usr`) is read-only. If you want to modify FS, you need to remount as wriable.
+
+```
+mount -o remount,rw /
+```
+
+This is resets after reboot so need to fix `/etc/fstab` when you want to mount FS with wriable on every boot
+
+## 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.
+
+# (Optional) Install OpenCL
+
+To use arm compute CL backend, install OpenCL.
+You can get OpenCL for tizen in Tizen Mali DDK.
+
+# Known issue
+- `ls -al` of root folder shows strange output.

+
+Ref: https://wiki.odroid.com/odroid-xu4/odroid-xu4
+
+eMMC card pre-installed Ubuntu 16.04
+
+Preparation for IO via serial cable
+- Refer to `minicom` section in xu4_tizen.md
+- To find the name of serial device, plug your odroid into your host machine and power it on. Then, run the following on your host:
+ ```
+ $ dmesg | grep tty
+ [ 0.000000] console [tty0] enabled
+ [322282.017985] usb 2-1: cp210x converter now attached to ttyUSB0
+ ```
+- Use `CTRL-a z o` > `Serial port setup` to enter the dialog
+- Set configuration `Serial Device` to `/dev/ttyUSB0` for the name of serial device
+- Baud should be `115200-8N1`
+- Set configuration `Hardware Flow Control` to `No` to enable communication(keyboard typing..)
+
+Connect
+- Connect eMMC to bottom of the board
+- Connect Serial Console to Host USB
+- Connect power and boot
+
+Login with serial console. you can login with `root` or default `odroid` account
+- `root` password: `odroid`
+- `odroid `password: `odroid`
+
+Set ethernet
