-# antsdr for openwifi
-
-## Introduction
-[ANTSDR](https://github.com/MicroPhase/antsdr-fw) is a SDR hardware platform based on [xilinx zynq7020](https://www.xilinx.com/products/silicon-devices/soc/zynq-7000.html) and [adi ad936x](https://www.analog.com/en/products/ad9361.html). It could be used as a traditional SDR device such as PlutoSDR or FMCOMMS2/3/4 with Xilinx evaluation board, and it also be used as hardware platform to support openwifi.
-This README file will give the instructions about how to make the openwifi image for antsdr in the [antsdr branch](https://github.com/MicroPhase/openwifi/tree/antsdr) of openwifi project.

-## Build openwifi Linux img from scratch
-- To build the openwifi image, you should install the Xilinx Vivado 2018.3 first.
-- Download [2019_R1-2020_02_04.img.xz](https://swdownloads.analog.com/cse/2019_R1-2020_02_04.img.xz) from [Analog Devices Wiki](https://wiki.analog.com/resources/tools-software/linux-software/zynq_images). Burn it to a SD card.
-    ```bash
-    sudo dd if= 2019_R1-2020_02_04.img of=/dev/sdb bs=1M
-    ```
-    The **sdb** is your sd card device, this could be different with your environment. 
-- Clone the opwnwifi project and checkoout to antsdr branch.
-  ```bash
-  git clone https://github.com/MicroPhase/openwifi.git
-  git checkout antsdr
-  ```
-- 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):
-  ```bash
-  export SDCARD_DIR=sdcard_mount_point
-  export XILINX_DIR=your_Xilinx_directory
-  export OPENWIFI_DIR=your_openwifi_directory
-  export BOARD_NAME=your_board_name
-  ```
-  For example:
-  ```bash
-  export SDCARD_DIR=/media/wcc/
-  export XILINX_DIR=/opt/Xilinx/
-  export OPENWIFI_DIR=/home/wcc/openwifi
-  export BOARD_NAME=antsdr
-  ```
-- Run script to update SD card:
-  ```bash
-  $OPENWIFI_DIR/user_space/update_sdcard.sh $OPENWIFI_DIR $XILINX_DIR $BOARD_NAME $SDCARD_DIR
-  ```
-- Config your board to SD card boot mode (check the 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**. 
-  ```
-  ssh root@192.168.10.122
-  ```
-- Setup routing/NAT **on the PC** for your board -- this internet connection is **important** for post installation/config.
-  ```
-  sudo sysctl -w net.ipv4.ip_forward=1
-  sudo iptables -t nat -A POSTROUTING -o NICY -j MASQUERADE
-  sudo ip route add 192.168.13.0/24 via 192.168.10.122 dev ethX
-  ```
-  **ethX** is the PC NIC name connecting the board ethernet. **NICY** is the PC NIC name connecting internet (WiFi or another ethernet).
-
-  For example:
-  ```
-  sudo sysctl -w net.ipv4.ip_forward=1
-  sudo iptables -t nat -A POSTROUTING -o wlan0 -j MASQUERADE
-  sudo ip route add 192.168.13.0/24 via 192.168.10.122 dev eth0
-  ```
-  
-  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
-  ```
-- Now you can start from [Quick start](https://github.com/MicroPhase/openwifi/tree/antsdr#quick-start) (Skip the image download and burn step)
