+# 晶晨 A311D 部署环境编译安装
+
+FastDeploy 基于 Paddle-Lite 后端支持在晶晨 NPU 上进行部署推理。
+更多详细的信息请参考：[PaddleLite部署示例](https://www.paddlepaddle.org.cn/lite/develop/demo_guides/verisilicon_timvx.html)。
+
+本文档介绍如何编译基于 PaddleLite 的 C++ FastDeploy 交叉编译库。
+
+相关编译选项说明如下：  
+|编译选项|默认值|说明|备注|  
+|:---|:---|:---|:---|  
+|ENABLE_LITE_BACKEND|OFF|编译A311D部署库时需要设置为ON| - |
+|WITH_TIMVX|OFF|编译A311D部署库时需要设置为ON| - |
+
+更多编译选项请参考[FastDeploy编译选项说明](./README.md)
+
+## 交叉编译环境搭建
+
+### 宿主机环境需求  
+- os：Ubuntu == 16.04
+- cmake： version >= 3.10.0  
+
+### 环境搭建
+可以进入 FastDeploy/tools/timvx 目录，使用如下命令一键安装：
+```bash
+cd FastDeploy/tools/timvx
+bash install.sh
+```
+也可以按照如下命令安装：
+```bash
+ # 1. Install basic software
+apt update
+apt-get install -y --no-install-recommends \
+  gcc g++ git make wget python unzip
+
+# 2. Install arm gcc toolchains
+apt-get install -y --no-install-recommends \
+  g++-arm-linux-gnueabi gcc-arm-linux-gnueabi \
+  g++-arm-linux-gnueabihf gcc-arm-linux-gnueabihf \
+  gcc-aarch64-linux-gnu g++-aarch64-linux-gnu
+
+# 3. Install cmake 3.10 or above
+wget -c https://mms-res.cdn.bcebos.com/cmake-3.10.3-Linux-x86_64.tar.gz && \
+  tar xzf cmake-3.10.3-Linux-x86_64.tar.gz && \
+  mv cmake-3.10.3-Linux-x86_64 /opt/cmake-3.10 && \
+  ln -s /opt/cmake-3.10/bin/cmake /usr/bin/cmake && \
+  ln -s /opt/cmake-3.10/bin/ccmake /usr/bin/ccmake
+```
+
+## 基于 PaddleLite 的 FastDeploy 交叉编译库编译
+搭建好交叉编译环境之后，编译命令如下：
+```bash
+# Download the latest source code
+git clone https://github.com/PaddlePaddle/FastDeploy.git
+cd FastDeploy  
+mkdir build && cd build
+
+# CMake configuration with A311D toolchain
+cmake -DCMAKE_TOOLCHAIN_FILE=./../cmake/toolchain.cmake \
+      -DWITH_TIMVX=ON  \
+      -DTARGET_ABI=arm64 \
+      -DCMAKE_INSTALL_PREFIX=fastdeploy-tmivx \
+      -DENABLE_VISION=ON \ # 是否编译集成视觉模型的部署模块，可选择开启
+      -Wno-dev ..
+
+# Build FastDeploy A311D C++ SDK
+make -j8
+make install
+```  
+编译完成之后，会生成 fastdeploy-tmivx 目录，表示基于 PadddleLite TIM-VX 的 FastDeploy 库编译完成。
+
+## 准备设备运行环境
+部署前要保证晶晨 Linux Kernel NPU 驱动 galcore.so 版本及所适用的芯片型号与依赖库保持一致，在部署前，请登录开发板，并通过命令行输入以下命令查询 NPU 驱动版本，晶晨建议的驱动版本为：6.4.4.3
+```bash
+dmesg | grep Galcore
+```  
+
+如果当前版本不符合上述，请用户仔细阅读以下内容，以保证底层 NPU 驱动环境正确。
+
+有两种方式可以修改当前的 NPU 驱动版本：
+1. 手动替换 NPU 驱动版本。（推荐）
+2. 刷机，刷取 NPU 驱动版本符合要求的固件。
+
+### 手动替换 NPU 驱动版本
+1. 使用如下命令下载解压 PaddleLite demo，其中提供了现成的驱动文件
+```bash
+wget https://paddlelite-demo.bj.bcebos.com/devices/generic/PaddleLite-generic-demo.tar.gz
+tar -xf PaddleLite-generic-demo.tar.gz
+```
+2. 使用 `uname -a` 查看 `Linux Kernel` 版本，确定为 `Linux` 系统 4.19.111 版本，
+3. 将 `PaddleLite-generic-demo/libs/PaddleLite/linux/arm64/lib/verisilicon_timvx/viv_sdk_6_4_4_3/lib/a311d/4.9.113` 路径下的 `galcore.ko` 上传至开发板。
+
+4. 登录开发板，命令行输入 `sudo rmmod galcore` 来卸载原始驱动，输入 `sudo insmod galcore.ko` 来加载传上设备的驱动。（是否需要 sudo 根据开发板实际情况，部分 adb 链接的设备请提前 adb root）。此步骤如果操作失败，请跳转至方法 2。
+5. 在开发板中输入 `dmesg | grep Galcore` 查询 NPU 驱动版本，确定为：6.4.4.3
+
+### 刷机
+根据具体的开发板型号，向开发板卖家或官网客服索要 6.4.4.3 版本 NPU 驱动对应的固件和刷机方法。
+
+更多细节请参考：[PaddleLite准备设备环境](https://www.paddlepaddle.org.cn/lite/develop/demo_guides/verisilicon_timvx.html#zhunbeishebeihuanjing)
