# SUDA_RISCV
本文档仅仅记录作者把玩开源FPGA开发板`荔枝糖`的经历。
## 安装 TD 驱动
* Linux环境
LicheeTang默认已经烧录了JTAG固件（用于烧录FPGA码流到配置芯片中，相当于是USB Blaster）
* Windows环境
参考[荔枝糖官方文档—安装TD驱动](http://tang.lichee.pro/get_started/driver.html)
## 烧写 FPGA 码流
* 注意要选择 `PROGRAM_FLASH` 模式
## 搭建开发环境
### 安装宿主机工具
```bash
sudo apt-get install autoconf automake autotools-dev curl libmpc-dev libmpfr-dev libgmp-dev gawk build-essential bison flex texinfo gperf libtool patchutils bc zlib1g-dev libexpat-dev libglib2.0-dev expect libusb-1.0-0-dev libftdi-dev
```
### 编译工具链
```bash
# 添加子模块
git submodule add https://github.com/riscv/riscv-gnu-toolchain.git riscv-gnu-toolchain
# 初始化子模块
git submodule update --init --recursive
# 创建编译目录
mkdir -p toolchains/build
cd toolchains/build
# 配置(32位处理器，支持的指令集为RV32GC，支持的ABI为ilp32)
# ilp32 (32-bit soft-float), ilp32d (32-bit hard-float), ilp32f (32-bit with single-precision in registers and double in memory)
../../riscv-gnu-toolchain/configure --prefix=/home/maoshengrong/SUDA_RISCV/toolchains/ --with-arch=rv32gc --with-abi=ilp32
# 编译
make newlib
# 测试
make report-newlib
```
### 编译qemu虚拟机
> 世界上在上一步中，已经编译好了两个qemu虚拟机，分别是`qemu-riscv32` 和 `qemu-riscv64` ，这里编译带操作系统的版本，即qemu-system-riscv32或者qemu-system-riscv64
```bash
# 创建编译目录
mkdir -p qemu/build
cd qemu/build
# 配置
../../riscv-gnu-toolchain/riscv-qemu/configure --prefix=/home/maoshengrong/SUDA_RISCV/qemu/ --target-list=riscv32-softmmu
# 编译
make -j4
# 安装
make install
```
### 编译OpenOCD
```bash
# 添加子模块
git submodule add https://github.com/riscv/riscv-openocd.git riscv-openocd
# 初始化子模块
git submodule update --init --recursive
# 生成configure文件
cd riscv-openocd
./bootstrap
cd ..
# 创建编译目录
mkdir -p openocd/build
cd openocd/build
# 配置
../../riscv-openocd/configure --prefix=/home/maoshengrong/SUDA_RISCV/openocd/
# 编译
make -j4
# 安装
make install
```
