Black Pill V1.2 — Zephyr Project Documentation

1. 背景

WeAct Black Pill V1.2开发板是一款基于STM32F401CC芯片的超低成本精简型开发板（详见STM32F401CC官网[5]）。该板采用STM32F401x系列的48引脚版本（参见STM32F401x参考手册[6]），WeAct的GitHub页面[2]。

2. 硬件信息

基于STM32F401CC芯片的Black Pill V3.0+开发板提供以下硬件组件：

STM32F401CCU6 in UFQFPN48 package

ARM® 32-bit Cortex® -M4 CPU with FPU

84 MHz max CPU frequency

VDD from 1.7 V to 3.6 V

256 KB Flash

64 KB SRAM

GPIO with external interrupt capability

1x12-bit, 2.4 MSPS ADC with 16 channels

DMA Controller

Up to 11 Timers (six 16-bit, two 32-bit, two watchdog timers and a SysTick timer)

USART/UART (3)

I2C (3)

SPI/I2S (5)

SDIO

USB 2.0 full-speed device/host/OTG controller with on-chip PHY

CRC calculation unit

96-bit unique ID

RTC

3. 管脚分布信息：

4. Zephyr默认外设映射

UART_1 TX/RX : PA9/PA10

I2C1 SCL/SDA : PB8/PB9

SPI1 CS/SCK/MISO/MOSI : PA4/PA5/PA6/PA7 (Routed to footprint for external flash)

PWM_4_CH1 : PB6

PWM_4_CH2 : PB7

ADC_1 : PA1

USER_PB : PA0

USER_LED : PC13

5. 烧录与调试

BlackPill_F401CC开发板支持以下运行器（runners）及对应的west命令：

	flash	debug	debugserver	rtt	attach
blackmagicprobe	✅	✅			✅
dfu-util	✅ (default)
jlink	✅	✅	✅	✅	✅
openocd	✅	✅ (default)	✅	✅	✅

5.1 DFU-Util工具

Zephyr对应BlackPill_F401CC项目默认使用dfu-util烧录。

连接USB-C数据线后，开发板将自动上电。强制进入DFU模式的操作方法：保持BOOT0开关按压状态，同时短按NRST开关后立即释放。

设备管理器里能看到"STM32 BOOTLOADER",说明F401进入到DFU下载模式。

解压dfu-util-0.11-binaries至zephyr-sdk目录下：

解压好后设置系统环境变量

将dfu-util的win64执行程序路径添加在系统变量里。

设置好后打开cmd终端

5.2 ST-LINK V2 + OpenOCD + GDB工具

首先淘宝购买ST-LINK V2 STM8/STM32仿真器固件比较旧，zephyr使用stlink检测固件会报错，需要先更新ST-LINK为最新版本。

去ST官网下载 stsw-link007

ST-Link 与 STM32F401CC 接线

ST-Link 引脚	STM32F401CC 引脚	备注
SWDIO	PA13	必须连接
SWCLK	PA14	必须连接
GND	GND	必须连接
RST	R	必须连接

下载 openocd-0.12.0-6至zephyr-sdk

解压好后设置系统环境变量

将openocd的bin执行程序路径添加在系统变量里。

下载arm-none-eabi-gcc-14.2.1至zephyr-sdk

将arm-none-eabi-gdb.exe的bin执行程序路径添加在系统变量里。

创建一个stm32f4.cfg的Tcl文件

# 选择 ST-Link 调试器
source [find interface/stlink.cfg]# 选择 SWD 协议
transport select dapdirect_swd# 目标芯片配置
source [find target/stm32f4x.cfg]reset_config srst_only

设置好后打开cmd终端, 验证openocd是否运行正常。

5.3 J-LINK工具

J-LINK 克隆调试器只能使用JLink_Windows_V758_x86_64版本，这个版本之后的版本都有JLink Clone检测功能。对于企业来说会带来一些不必要的麻烦，企业还是使用正版J-LINK硬件。

下载安装JLink_Windows_V758_x86_64，同样需要设置系统环境变量。

设置好后打开cmd终端, 验证JLink是否运行正常。
