-* Connect the board to PC. (PC IP address should be 192.168.10.1). Power on the board. Then from PC:
-```
-ssh root@192.168.10.122
-(password: openwifi)
-cd openwifi
-cp rf_init_board_name.sh rf_init.sh 
-(If there isn't rf_init.sh, rename your board rf script, such as rf_init_adrv9361z7035.sh, to rf_init.sh for wgd.sh to call)
-service network-manager stop
-./wgd.sh
-(For fmcomms4, you need an extra command: ./set_ant.sh rx1 tx1)
-ifconfig sdr0 up
-iwlist sdr0 scan
-(you should see the Wi-Fi scan result)
-```
-* Setup openwifi hotspot over topology: client -- (sdr0)|board|(eth0) -- (***ethX***)|PC|(***ethY***) -- internet
-  * Enable **IP forwarding** on both **board** and **PC** (uncomment net.ipv4.ip_forward=1 in /etc/sysctl.conf)
-  * Then, on board:
-
-        ifconfig sdr0 192.168.13.1
-        route add default gw 192.168.10.1
-        service isc-dhcp-server restart
-        hostapd hostapd-openwifi.conf
-  * Then, on PC:
-
-        sudo iptables -t nat -A POSTROUTING -o ethY -j MASQUERADE
-        sudo ip route add 192.168.13.0/24 via 192.168.10.122 dev ethX
-  * Now you can connect openwifi by your devices (phone, laptop, etc)
-* Connect openwifi to another hotspot. Terminate hostapd, edit wpa-connect.conf properly, then:
-        
-        ./wgd.sh
-        (For fmcomms4, you need an extra command: ./set_ant.sh rx1 tx1)
-        route del default gw 192.168.10.1
-        wpa_supplicant -i sdr0 -c wpa-connect.conf
-        (Wait for connection done, then open another ssh terminal)
-        dhclient sdr0
-        (Wait for its done, then you should have connection)
-
-* Real-time control/config via "sdrctl" (register, time slice config, etc), please go to openwifi/doc.
-
-* ***Note***: If openwifi stops working after ~2 hours, it means the evaluation license of Xilinx Viterbi decoder has expired. You need to power cycle the board. Run this command several times on board to confirm:
-  
-        root@analog:~/openwifi# ./sdrctl dev sdr0 get reg rx 20
-        SENDaddr: 00040050
-        reg  val: 34be0123
-        (If the last number of reg val is always 3, that means the Viterbi decoder stops working)
-
-**Build openwifi Linux img based on openwifi FPGA and driver:**
-
-* Install Vivado/SDK 2017.4.1 (If you don't need to re-compile FPGA, WebPack version without license is enough)
-* Get pre-built FPGA files from openwifi-hw repository.
-```
-git submodule init openwifi-hw
-git submodule update openwifi-hw
-cd openwifi-hw
-git checkout master
-git pull
-```
-* Build Linux kernel and modules:
-```
-export XILINX_DIR=your_Xilinx_directory
-cd openwifi
-git submodule init adi-linux
-git submodule update adi-linux
-(Will take a while)
-cd adi-linux
-git reset --hard 4220d5d24c6c7589fc702db4f941f0632b5ad767
-cp ../kernel_boot/kernel_config ./.config

-(Answer "y" to Xilinx DMA Engines (XILINX_DMA_ENGINES) [N/y/?] (NEW))
-make modules
-```
-* Build openwifi Linux driver modules:
-```
-export OPENWIFI_DIR=your_openwifi_directory
-cd $OPENWIFI_DIR/driver
-./make_all.sh $XILINX_DIR/SDK/2017.4/ $OPENWIFI_DIR/adi-linux/
-```
-* Build openwifi Linux devicetree:
-```
-export BOARD_NAME=board_name
-(Check the board_name naming in the table of supported SDR platforms)
-cd $OPENWIFI_DIR/kernel_boot/boards/$BOARD_NAME
-dtc -I dts -O dtb -o devicetree.dtb devicetree.dts
-cp devicetree.dtb $OPENWIFI_DIR/kernel_boot/
-```
-* Build openwifi BOOT.BIN based on FPGA files generated in openwifi-hw:
-```
-cd $OPENWIFI_DIR/kernel_boot
-source $XILINX_DIR/SDK/2017.4/settings64.sh
-./build_boot_bin.sh ../openwifi-hw/boards/$BOARD_NAME/sdk/system_top_hw_platform_0/system.hdf ./boards/$BOARD_NAME/u-boot.elf
-(u-boot.elf is renamed from the compressed file in the board directory of original Analog Devices SD card boot partition)
-```
-* Prepare correct rf_init.sh in host openwifi/user_space
-```
-cd $OPENWIFI_DIR/user_space
-cp rf_init_board_name.sh rf_init.sh 
-(If there isn't rf_init.sh, rename your board rf script, such as rf_init_adrv9361z7035.sh, to rf_init.sh for "wgd.sh remote" to download)
-```
-* Download [2017_R1-2018_01_29.img.xz](http://swdownloads.analog.com/cse/2017_R1-2018_01_29.img.xz) from [Analog Devices Wiki](https://wiki.analog.com/resources/tools-software/linux-software/zynq_images). Burn it into a SD card via your PC.
-* Mount SD card BOOT/rootfs partitions to SDCARD_DIR directory of your PC (If it is mounted automatically, find the directory). Then copy built files to SD card via your PC. (You can also update files over ftp/ssh after your full system runs. Please check next section. Read carefully user_space/sdcard_boot_update.sh and set your ftp root directory to $OPENWIFI_DIR in your PC):
-```
-export SDCARD_DIR=sdcard_mount_point
-cp $OPENWIFI_DIR/kernel_boot/boards/$BOARD_NAME/devicetree.dtb $SDCARD_DIR/BOOT
-cp $OPENWIFI_DIR/kernel_boot/output_boot_bin/BOOT.BIN $SDCARD_DIR/BOOT
-cp $OPENWIFI_DIR/adi-linux/arch/arm/boot/uImage $SDCARD_DIR/BOOT
-cd $SDCARD_DIR/BOOT
-sync
-
-sudo mkdir $SDCARD_DIR/rootfs/root/openwifi
-sudo find $OPENWIFI_DIR/driver -name \*.ko -exec cp {} $SDCARD_DIR/rootfs/root/openwifi/ \;
-sudo cp $OPENWIFI_DIR/user_space/* $SDCARD_DIR/rootfs/root/openwifi/ -rf
-
-sudo mkdir $SDCARD_DIR/rootfs/lib/modules
-sudo mkdir $SDCARD_DIR/rootfs/lib/modules/4.14.0-g4220d5d
-sudo find $OPENWIFI_DIR/adi-linux -name \*.ko -exec cp {} $SDCARD_DIR/rootfs/lib/modules/4.14.0-g4220d5d/ \;
-sudo rm $SDCARD_DIR/rootfs/lib/modules/4.14.0-g4220d5d/{axidmatest.ko,xilinx_dma.ko,adi_axi_hdmi.ko,ad9361_drv.ko} -f
-
-sudo rm $SDCARD_DIR/rootfs/etc/udev/rules.d/70-persistent-net.rules
-sudo cp $OPENWIFI_DIR/kernel_boot/70-persistent-net.rules $SDCARD_DIR/rootfs/etc/udev/rules.d/
-(Above rule will auto-rename wlan0 to sdr0 which is the openwifi NIC name)
-cd $SDCARD_DIR/rootfs
-sync
-```
-**Run Linux and do some post-config:**
-
-* Insert the SD card to the board, power on and run serial console (such as minicom) from a PC via USB-UART cable to the board. After booting completes, in the PC serial console:
-```
-depmod
-(Ignore the error messages)
-modprobe mac80211
-(if you get error like: could not open moddep file 'lib/modules/4.14.0XXXYYYZZZ/modules.dep.bin', you could make a symbol link and modprobe again)
-ln -s /lib/modules/4.14.0-g4220d5d /lib/modules/4.14.0XXXYYYZZZ
-depmod
-modprobe mac80211
-
-cd openwifi
-cp rf_init_board_name.sh rf_init.sh 
-(rename your board rf script, such as rf_init_adrv9361z7035.sh, to rf_init.sh for wgd.sh to call)
-./wgd.sh
-(For fmcomms4, you need an extra command: ./set_ant.sh rx1 tx1)
-(Wait for the completion)
-ifconfig
-(You should see sdr0 interface)
-iwlist sdr0 scan
-(You should see the Wi-Fi scan results)
-```
-* Config ssh server and ethernet IP address of the board. In the PC serial console:
-```
-passwd
-(ssh server needs a password, such as "openwifi")
-Add "UseDNS no" to /etc/ssh/sshd_config, otherwise ssh login takes too long time
-Set static IP to board (If you have DHCP server on PC, you can skip this step)
-Add following content to /etc/network/interfaces
-  auto lo eth0
-  iface lo inet loopback
-  iface eth0 inet static
-          address 192.168.10.122
-          netmask 255.255.255.0
-Add following content to /etc/resolv.conf
-  nameserver 8.8.8.8
-  nameserver 4.4.4.4
-
-Disable update (long time hang) on boot or ssh session:
-  sudo chmod -x /etc/update-motd.d/90-updates-available
-  sudo chmod -x /etc/update-motd.d/91-release-upgrade
-
-reboot the board, and set proper IP (192.168.10.1) of the connected PC, then from the PC:
-ssh roo@192.168.10.122
-(password: openwifi)
-route add default gw 192.168.10.1
-(above route is necessary for your board to access internent via your PC)
-```
-* Make on board file update easier:
-  * Option 1: Access the board disk/rootfs from Ubuntu PC: "File manager --> Connect to Server...", input: sftp://root@192.168.10.122/root . Then you can operate files on board like normal files on your disk. To update files that need to be in boot partition (BOOT.BIN, uImage and devicetree.dtb), you can transfer those files to rootfs firstly, then on board:
-  
-         mkdir /sdcard
-         mount /dev/mmcblk0p1 /sdcard
-         cp file /sdcard
-         cd /sdcard
-         sync
-         cd /
-         umount /sdcard
-         (Remember to power cycle the board)
-  * Option 2: Setup [ftp server](https://help.ubuntu.com/lts/serverguide/ftp-server.html) on PC, allow anonymous and change ftp root directory to $OPENWIFI_DIR. Then on board:
-  
-        mkdir /sdcard
-        ./sdcard_boot_update.sh
-        (Above command downloads uImage, BOOT.BIN and devicetree.dtb, then copy them into boot partition. Remember to power cycle)
-        ./wgd.sh remote
-        (Above command downloads driver files, and brings up sdr0)
-        (For fmcomms4, you need an extra command: ./set_ant.sh rx1 tx1)
-
-**Compile sdrctl on the board** ("On the board" means that you login to the board via ssh)
-```
-sudo apt-get install libnl-3-dev
-sudo apt-get install libnl-genl-3-dev
-(Please find the next section to see how to connect board to the internet via your PC)
-(or find out .deb files by above commands and copy .deb to the board, if you do not have internet)
-
-copy $OPENWIFI_DIR/user_space/sdrctl_src to the board, then on the board:
-cd sdrctl_src
-chmod +x version.sh
-make
-```
-
-**Internet config**
-* Connect board to internet. Topology: board|(eth0) -- (***ethX***)|PC|(***ethY***) -- internet
-  * Enable **IP forwarding** on both **board** and **PC** (uncomment net.ipv4.ip_forward=1 in /etc/sysctl.conf)
-  * On board:
+## Quick start
+- Burn [openwifi image](https://users.ugent.be/~xjiao/openwifi-1.1.0-taiyuan.img.xz) into a SD card (Double clikc in Ubuntu or "Open With Disk Image Writer"). You can see two partitions (BOOT and rootfs) when you insert the SD card to your PC. You need to use **correct files in the BOOT partition** according to the **platform you have**. Just **overwrite** the files in the base directory with the files in **board_name** directory of BOOT partiton.
+- Connect two antennas to RXA/TXA ports. Config the board to SD card boot mode (check your board manual). Insert the SD card to the board. 
+- Power on. login to the board from your PC (PC Ethernet should have IP 192.168.10.1) with one time password **analog**.
  ```
-  route add default gw 192.168.10.1
+  ssh root@192.168.10.122
  ```
-  * On PC. After this your board should have internet via NAT through your PC.
-
+- Setup routing/NAT **on the PC** for the board -- this is **important** for post installation/config.
  ```
+  sudo sysctl -w net.ipv4.ip_forward=1
  sudo iptables -t nat -A POSTROUTING -o ethY -j MASQUERADE
-  ```
-* Setup AP for Wi-Fi client. Topology: client -- (sdr0)|board|(eth0) -- (***ethX***)|PC|(***ethY***) -- internet
-  * On board: Install dhcp server preparing for serving your openwifi clients via hostapd.
-  ```
-  sudo apt-get install isc-dhcp-server
-  sudo apt-get install Haveged
-  sudo apt-get install hostapd
-  cd openwifi
-  cp dhcpd.conf /etc/dhcp/dhcpd.conf
-  service network-manager stop
-  ./wgd.sh
-  (For fmcomms4, you need an extra command: ./set_ant.sh rx1 tx1)
-  ifconfig sdr0 up
-  ifconfig sdr0 192.168.13.1
-  route add default gw 192.168.10.1
-  service isc-dhcp-server restart
-  hostapd hostapd-openwifi.conf
-  ```
-  * On PC:
-  ```
  sudo ip route add 192.168.13.0/24 via 192.168.10.122 dev ethX
  ```
-  * Now you can connect openwifi hotspot from your phone/laptop and access the internet.
+  **ethX** is the PC NIC name connecting the board. **ethY** is the PC NIC name connecting internet.
+  
+  If you want, uncommenting "net.ipv4.ip_forward=1" in /etc/sysctl.conf to make IP forwarding persistent on PC.
+- Run **one time** script on board to complete post installation/config (After this, password becomes **openwifi**)
+  ```
+  cd ~/openwifi && ./post_config.sh
+  ```
+- Run openwifi AP together with the on board webserver
+  ```
+  ~/openwifi/fosdem.sh
+  ```
+- After you see the "openwifi" SSID on your device (Phone/Laptop/etc), connect it. Browser to 192.168.13.1 on your deivce, you should see the webpage hosted by the webserver on board.
+  - Note 1: If your device doesn't support 5GHz (ch44), please change the **hostapd-openwifi.conf** on board and re-run fosdem.sh.
+  - Note 2: After ~2 hours, the Viterbi decoder will halt (Xilinx Evaluation License). Just power cycle the board if it happens.

-**Connecting a client to openwifi AP in 2.4GHz**
+## Basic operations
+The board actually is an Linux/Ubuntu computer which is running **hostapd** to offer Wi-Fi AP functionality over the Wi-Fi Network Interface (NIC). The NIC is implemented by openwifi-hw FPGA design. We use the term **"On board"** to indicate that the commands should be executed after ssh login to the board. **"On PC"** means the commands should run on PC.
+- Bring up the openwifi NIC sdr0:
+  ```
+  cd ~/openwifi && ./wgd.sh
+  ```
+- Use openwifi as client to connect other AP (Change wpa-connect.conf on board firstly):
+  ```
+  route del default gw 192.168.10.1
+  wpa_supplicant -i sdr0 -c wpa-connect.conf &
+  dhclient sdr0
+  ```
+- Use openwifi in ad-hoc mode: Please check **sdr-ad-hoc-up.sh** and **sdr-ad-hoc-join.sh**.
+- Use openwifi in monitor mode: Please check **monitor_ch.sh**.
+- The Linux native Wi-Fi tools/Apps (iwconfig/ifconfig/iwlist/iw/hostapd/wpa_supplicant/etc) can run over openwifi NIC in the same way as commercial Wi-Fi chip. 
+- **sdrctl** is a dedicated tool to access openwifi driver/FPGA, please check doc directory for more information. 
+
+## Update FPGA
+
+Since the pre-built SD card image might not have the latest bug-fixes/updates, it is recommended to udpate the fpga bitstream on board.
+
+- Install Vivado/SDK 2017.4.1 (If you don't need to generate new FPGA bitstream, WebPack version without license is enough)
+- Setup environment variables (use absolute path):
+  ```
+  export XILINX_DIR=your_Xilinx_directory
+  export OPENWIFI_DIR=your_openwifi_directory
+  export BOARD_NAME=your_board_name
+  ```
+- Get the latest FPGA bitstream from openwifi-hw, generate BOOT.BIN and transfer it on board via ssh channel:
+  ```
+  $OPENWIFI_DIR/user_space/get_fpga.sh $OPENWIFI_DIR
+  $OPENWIFI_DIR/user_space/boot_bin_gen.sh $OPENWIFI_DIR $XILINX_DIR $BOARD_NAME
+  scp $OPENWIFI_DIR/kernel_boot/boards/$BOARD_NAME/output_boot_bin/BOOT.BIN root@192.168.10.122:
+  ```
+- On board: Put the BOOT.BIN into the BOOT partition.
+  ```
+  mount /dev/mmcblk0p1 /mnt
+  cp ~/BOOT.BIN /mnt
+  umount /mnt
+  ```
+  **Power cycle** the board to load new FPGA bitstream.
+
+## Update Driver
+
+Since the pre-built SD card image might not have the latest bug-fixes/updates, it is recommended to udpate the driver on board.
+- Prepare Analog Devices Linux kernel source code (only need to run once):
+  ```
+  $OPENWIFI_DIR/user_space/prepare_kernel_src.sh $OPENWIFI_DIR $XILINX_DIR
+  ```
+- Compile the latest openwifi driver
+  ```
+  $OPENWIFI_DIR/driver/make_all.sh $OPENWIFI_DIR $XILINX_DIR
+  ```
+- Copy the driver files to the board via ssh channel
+  ```
+  scp `find $OPENWIFI_DIR/driver/ -name \*.ko` root@192.168.10.122:openwifi/
+  ```
+  Now you can use **wgd.sh** on board to load the new openwifi driver.
+
+## Update sdrctl
+- Copy the sdrctl source files to the board via ssh channel
+  ```
+  scp `find $OPENWIFI_DIR/user_space/sdrctl_src/ -name \*.*` root@192.168.10.122:openwifi/sdrctl_src/
+  ```
+- Compile the sdrctl **on board**:
+  ```
+  cd ~/openwifi/sdrctl_src/ && make && cp sdrctl ../ && cd ..
+  ```
+## Easy Access and etc
+
+- FPGA and driver on board update scripts
+  - Setup [ftp server](https://help.ubuntu.com/lts/serverguide/ftp-server.html) on PC, allow anonymous and change ftp root directory to $OPENWIFI_DIR.
+  - On board:
+  ```
+  ./sdcard_boot_update.sh $BOARD_NAME
+  (Above command downloads uImage, BOOT.BIN and devicetree.dtb, then copy them into boot partition. Remember to power cycle)
+  ./wgd.sh remote
+  (Above command downloads driver files, and brings up sdr0)
+  ```
+- Access the board disk/rootfs like a disk: 
+   - On PC: "File manager --> Connect to Server...", input: sftp://root@192.168.10.122/root
+   - Input password "openwifi"
+
+## Build openwifi Linux img from scratch
+- Download [2017_R1-2018_01_29.img.xz](http://swdownloads.analog.com/cse/2017_R1-2018_01_29.img.xz) from [Analog Devices Wiki](https://wiki.analog.com/resources/tools-software/linux-software/zynq_images). Burn it to a SD card.
+- Insert the SD card to your Linux PC. Find out the mount point (that has two sub directories BOOT and rootfs), and setup environment variables (use absolute path):
+  ```
+  export SDCARD_DIR=sdcard_mount_point
+  export XILINX_DIR=your_Xilinx_directory
+  export OPENWIFI_DIR=your_openwifi_directory
+  export BOARD_NAME=your_board_name
+  ```
+- Run script to update SD card:
+  ```
+  $OPENWIFI_DIR/user_space/update_sdcard.sh $OPENWIFI_DIR $XILINX_DIR $BOARD_NAME $SDCARD_DIR
+  ```
+- Now you can start from [Quick start](#Quick-start)
+
+## Special note for 11b

 Openwifi only applies OFDM as its modulation scheme and as a result, it is not backward compatible with 802.11b clients or modes of operation. This is usually the case during beacon transmission, connection establishment, and robust communication.

@ -304,20 +193,19 @@ For hostapd program, 802.11b rates can be suppressed using configuration command

 On the other hand, the wpa_supplicant program on the client side (commercial Wi-Fi dongle/board) cannot suppress 802.11b rates out of the box in 2.4GHz band, so there will be an issue when connecting openwifi (OFDM only). A patched wpa_supplicant should be used at the client side.

+## Porting guide

-## cite openwifi project
+This section explains the porting work by showing the differences between openwifi and Analog Devices reference design. We use **2018_r1** of [HDL Reference Designs](https://github.com/analogdevicesinc/hdl).
+- Open the fmcomms2 + zc706 reference design at hdl/projects/fmcomms2/zc706 (Please read Analog Devices help)
+- Open the openwifi design zc706_fmcs2 at openwifi-hw/boards/zc706_fmcs2 (Please read openwifi-hw repository)
+- "Open Block Design", you will see the differences between openwifi and the reference design. Both in "diagram" and in "Address Editor".
+- The address/interrupts of FPGA blocks hooked to the ARM bus should be put/aligned to the devicetree file openwifi/kernel_boot/boards/zc706_fmcs2/devicetree.dts. Linux will parse the devicetree.dtb when booting to know information of attached deivce (FPGA blocks in our case).
+- We use dtc command to get devicetree.dts converted from devicetree.dtb in [Analog Devices Linux image](https://wiki.analog.com/resources/tools-software/linux-software/zynq_images), then do modification according to what we have added/modified to the reference design.
+- Please learn the script in [[Build openwifi Linux img from scratch](#Build-openwifi-Linux-img-from-scratch)] to understand how we generate devicetree.dtb, BOOT.BIN and Linux kernel uImage and put them together to build the full SD card image.
