GD32VW553-IOT 测评和vscode开发环境搭建

1. 背景介绍

iCEasy商城的产品, Firefly Workshop 萤火工厂的样片, 是一款基于GD32VW553 MCU的开源硬件, 这款MCU内置了32bit的RISC-V内核, 支持双模无线WIFI-6和BLE-5.2, 最高主频可达160Mhz.

本人曾在公司参与开发了一款基于RISC-V内核的触控芯片, 所以之前接触过兆易更早的一款RISC-V的MCU, 即GD32VF103, 同时也使用过GD32W5系列的IOT MCU, 这次正好看到了结合GD的V和W联手的产品, 于是就申请了一块板子回来研究研究。

同样想要玩玩这款芯片的小伙伴, 可以去申请样品, 链接如下：https://www.iceasy.com/

2. 准备工作

样品拿到手之后, 先去GD官网把手册和开发软件下载一下, 同时也可以去iCEasy商城网站上下载对应资料。https://www.gd32mcu.com/cn/download/0?kw=GD32VW5

用户手册、数据手册
固件库、原理图
GD32AllInOneProgrammer_win
GD32EmbeddedBuilder

3. 展示一下

实物图系统框图

在这里插入图片描述

4. 创建工程

基于GD32EmbeddedBuilder可以很方便快速的把demo程序跑起来, 下面是创建工程的步骤, 软件提供了MCU的ARM C project和RISC-V Cproject, 本次测试的芯片是基于RISC-V的, 因此选择对应的选项.
在这里插入图片描述

5. 工程结构

Firmware目录中是GD的外设库和RISC-V的驱动库, inc和src是具体实现的功能, 可以参考官方提供的demo来移植想要的功能, idscripts提供的链接文件, 指定了芯片的内存大小和布局, openocd提供了基于gd_link的openocd下载脚本。

比较需要注意的是Firmware/RISC-V/env_Eclipse和stubs文件夹, 其中stubs文件夹提供的是一些系统调用的桩函数, env_Eclipse文件夹下提供的entry.S和start.S实现了芯片启动部分和中断向量表设置。

在这里插入图片描述

编译选项如图所示:
riscv-nuclei-elf-gcc -march=rv32imac -mabi=ilp32 -mcmodel=medlow -msmall-data-limit=8 -mdiv -O0 -fmessage-length=0 -fsigned-char -ffunction-sections -fdata-sections -g3 -std=gnu11 -DGD_ECLIPSE_GCC -DUSE_STDPERIPH_DRIVER ........

riscv-nuclei-elf-gcc -march=rv32imac -mabi=ilp32 -mcmodel=medlow -msmall-data-limit=8 -mdiv -O0 -fmessage-length=0 -fsigned-char -ffunction-sections -fdata-sections -g3 -Wa,-adhlns=Firmware/RISCV/env_Eclipse/entry.o.lst -x assembler-with-cpp -I"../Firmware/RISCV/drivers" -c -o "Firmware/RISCV/env_Eclipse/entry.o" "../Firmware/RISCV/env_Eclipse/entry.S"

riscv-nuclei-elf-gcc -march=rv32imac -mabi=ilp32 -mcmodel=medlow -msmall-data-limit=8 -mdiv -O0 -fmessage-length=0 -fsigned-char -ffunction-sections -fdata-sections -g3 -Wl,-Map,"gd32vw553_test.map" -T GD32VW55X.lds -nostartfiles -Xlinker --gc-sections -L"../ldscripts/" --specs=nano.specs --specs=nosys.specs -o "gd32vw553_test.elf" ......

6. 代码下载

启动模式修改, 从表中可以看出, 将BOOT0接高之后, 会从Bootloader启动, 就能用串口ISP更新固件, 根据原理图可以看出, 首先需要将R4和R5两个电阻焊接上

7. 串口LOG打印和LED闪烁

使用的是串口0和PA15作为LED口

  int main(void){/* configure systick */systick_config();eclic_priority_group_set(ECLIC_PRIGROUP_LEVEL3_PRIO1);/* enable the led clock */rcu_periph_clock_enable(RCU_GPIOA);/* configure led GPIO port */gpio_mode_set(GPIOA, GPIO_MODE_OUTPUT, GPIO_PUPD_NONE, GPIO_PIN_15);gpio_output_options_set(GPIOA, GPIO_OTYPE_PP, GPIO_OSPEED_25MHZ, GPIO_PIN_15);GPIO_BC(GPIOA) = GPIO_PIN_15;/* initilize the LEDs, USART and key */gd_eval_com_init(EVAL_COM0);/* print out the clock frequency of system, AHB, APB1 and APB2 */printf("CK_SYS is %d\r\n", rcu_clock_freq_get(CK_SYS));printf("CK_AHB is %d\r\n", rcu_clock_freq_get(CK_AHB));printf("CK_APB1 is %d\r\n", rcu_clock_freq_get(CK_APB1));printf("CK_APB2 is %d\r\n", rcu_clock_freq_get(CK_APB2));while(1) {delay_1ms(500);GPIO_TG(GPIOA) = GPIO_PIN_15;}}

在桩函数中修改串口打印的功能

 int _put_char(int ch){usart_data_transmit(EVAL_COM0, (uint8_t) ch );while (usart_flag_get(EVAL_COM0, USART_FLAG_TBE)== RESET){}return ch;}

将代码下载进板子, 打开串口助手, 可以看到log打印

8. vscode开发环境搭建

编译工具链配置（这里windows平台工具链下载就不多说了，下载对应工具，然后添加环境变量可以找找其他教程）

gcc
riscv-none-embed-gcc
ninja
cmake
cacache

9. Timer Breath LED

移植DEMO中的Timer Breath LED功能

10. 移植MBL和MSDK

SDK 最终生成的执行程序主要有两个：一个是 MBL（Main Bootloader），一个是 MSDK
（ Main SDK ）。它们最终都将被烧写到 FLASH 运行。上电之后，程序将从 MBL 的
Reset_Handler 启动，然后跳转到 MSDK 主程序运行

三个配置文件

GD32VW55x_RELEASE/config/platform_def.h 用于配置WIFI 和 BLE
GD32VW55x_RELEASE/config/config_gdm32.h 用于设置Flahs和SRAM内存布局
GD32VW55x_RELEASE/MSDK/app/app_cfg.h 用于配置一些无线相关的应用, 例如： ATCMD，阿里云， MQTT， COAP

注：通过修改 app_cfg.h 内的宏CONFIG_BLE_LIB 可切换BLE library。将 CONFIG_BLE_LIB 配
置为 BLE_LIB_MIN，工程编译时会选择libble.a，同时头文件会include ble_config_min.h;将CONFIG_BLE_LIB 配置为BLE_LIB_MAX，工程编译时会选择 libble_max.a，同时头文件会include ble_config_max.h。

工程配置
编译工程

Embedded Builder IDE 下编译和调试 SDK。首先下载GD32VW55x_RELEASE, 目前官网最新版本是1.0.3a.
将workspaces 指向 GD32VW55x_RELEASE 目录
然后选择 MSDK 或 MBL 工程进行导入, 路径为GD32VW55x_RELEASE/MBL/project/eclipse和GD32VW55x_RELEASE/MSDK/projects/eclipse/msdk
分别编译 MBL 和 MSDK 工程
MSDK 编译完成之后，会调用 MSDK/projects/image_afterbuild.bat 生成 image-ota.bin 和image-all.bin。并将生成的 bin 文件拷贝至/scripts/images 内, image-ota.bin是MSDK工程生成的bin文件，可用于OTA 升级， image-all.bin是MBL(mbl.bin)和 MSDK(image-ota.bin)的组合，该固件可用于生产，烧录到 FLASH 中运行
