前言

该页面将介绍一些较为简单基础的测试case 功能，目前包括 freertos；log等级输出；boot2；这一小节将会为您先详细介绍如何 编译 烧录 如何下载烧录工具等基本信息。

源码编译:

在对应 Case 的文件夹下有一个 README.md 文件，该文件中根据不同的开发板型号有不同编译的参数，例如 bl616 ： 

- BL616/BL618

```
make CHIP=bl616 BOARD=bl616dk
```
#以上为README文件中的内容，根据内容直接执行对应make编译指令即可

make如果成功，你会在终端看到：

Generate .../bouffalo_sdk/examples/freertos/build/build_out/freertos_bl616.bin（示例） 代表生成了对应可供烧录的固件。

开发板烧录：

执行make命令后，在该文件夹下会生成一个build目录，在文件夹中有一个生成的固件 freertos_bl616.bin ，该文件用于烧录直接使用（类似于keil生成的.hex文件）。

其具体路径为 .../bouffalo_sdk/examples/freertos/build/build_out/freertos_bl616.bin

下载烧录工具：

下载BLDevCube工具：下载后解压即可直接使用。

https://dev.bouffalolab.com/

烧录具体步骤：

Step1：打开DevCube选择对应开发板型号。

Step2：选择对应的 .bin 文件，选择对应的串口。

注意：要选择IOT并勾选enable

Step3：

按住boot键按一下复位键（按复位时boot键不松开），然后点击Create & Download。查看下方的输出信息是否烧录成功。

Demo:FreeRTOS

在Bouffalo SDK上使用FreeRTOS APP

源码介绍：

该文件的源码在 bouffalo_sdk/examples/freertos/main.c中，该测试 demo 简单测试了一些组件，包括Semaphore，Mutex，Queue，Priority 的基本简单测试。

测试分为两个阶段：

阶段一以消费者生产者模型测试信号量和信号队列组件，共生成三个Task。阶段结束后Task自动销毁。

阶段二以共简单共享资源简单测试Task争夺临界资源的方式测试互斥量，途中高优先级的任务将启动并占用CPU一段时间以此测试抢占任务调度。

源码部分输出：

Demo:bflog

Demo介绍：

该部分代码储存在 bouffalo_sdk/examples/bflog/barebone_sync 路径下，主要测试该开发板不同级别的log输出功能；

filter对输出日志的过滤功能。bflog分为五个级别，分别为：

日志等级 说明 基本应用场景
FATL 致命错误（Fatal） 系统无法继续运行的灾难性事件（如核心崩溃、数据损坏），需立即人工干预并终止程序。
ERRO 错误（Error） 影响当前操作的关键错误（如功能失效、外部服务异常），但系统仍可部分运行，需尽快处理。
WARN 警告（Warning） 非关键性异常或潜在风险（如配置降级、资源不足），需关注但无需立即行动。
INFO 信息（Info） 常规运行状态记录（如服务启动、关键操作完成），用于监控系统健康状态。
DBUG 调试（Debug） 开发/测试阶段的详细运行细节（如变量值、逻辑分支），用于定位问题原因。
TRAC 跟踪（Trace） 最细粒度的执行路径追踪（如函数调用栈、循环过程），用于深度分析复杂逻辑。

barebone_sync：

该部分主要是裸机测试了以上的各个等级log输出，filter过滤。

部分输出：

============================== disable all output

freertos_async：

该部分测试了在FreeRTOS下log的输出是否正常。

该case创建了两个任务，消费者和生产者，从信号队列中进行获取和放入的经典场景来测试log。

消费者任务和生产者任务具体代码放在同目录下的： thread_consumer; thread_producer;中。

部分输出：

Demo:helloworld

Demo介绍：

该demo测试基本日志等级输出，该Demo是对bflog加了一层封装，比如控制日志输出等级，控制是否使用严重等级颜色输出。

保存路径： bouffalo_sdk/examples/helloworld

在当前默认情况下的输出如下： 

===========================
uart  sig1:ffffffff, sig2:0000f32f
clock gen1:9ffffffd, gen2:0fff0c11
xtal:40000000Hz(crystal)
board init done
===========================
[F][MAIN] hello world fatal
[E][MAIN] hello world error
[W][MAIN] hello world warning
[I][MAIN] hello world information
hello world fatal raw
hello world error raw
hello world warning raw
hello world information raw

通过代码对应可以看到部分代码没有输出，部分代码有颜色而部分代码没有颜色。 没有输出的部分是因为 LOG_LEVEL 的定义级别导致没有输出： 

#if (CONFIG_LOG_LEVEL >= 4)
#define LOG_D(...)  BFLOG_D((void *)&__bflog_recorder, __VA_ARGS__)
#define LOG_RD(...) BFLOG_RD((void *)&__bflog_recorder, __VA_ARGS__)
#else
#define LOG_D(...)  ((void)0)
#define LOG_RD(...) ((void)0)
#endif

#if (CONFIG_LOG_LEVEL >= 5)
#define LOG_T(...)  BFLOG_T((void *)&__bflog_recorder, __VA_ARGS__)
#define LOG_RT(...) BFLOG_RT((void *)&__bflog_recorder, __VA_ARGS__)
#else
#define LOG_T(...)  ((void)0)
#define LOG_RT(...) ((void)0)
#endif

是否有颜色则取决于是否带有R,在引用文件中可以看到： 

#define BFLOG_RF(_log, ...) BFLOG_X(_log, BFLOG_LEVEL_RAW | BFLOG_LEVEL_FATAL, (BFLOG_TAG), ##__VA_ARGS__)

以上配置可以在同级目录下的 proj.conf 中。

Demo:log_dbg_assert

这部分代码和Demo:helloworld 基本一致，但是多了测试断言输出的功能。

保存在 SDK 下的： bouffalo_sdk/examples/log_dbg_assert

在代码中先进行了一个阶乘的递归函数，每一次递归以及判读啊都会输出断言信息以此测试断言输出。

示例输出：

Demo:boot2 isp

这部分代码是一个bootloader程序，具备 安全启动、双分区更新、压缩支持、多核管理 等工业级特性。

该demo存放在 SDK 下的：/home/user/FromGit/bouffalo_sdk/examples/boot2_isp 路径下。

主要功能

  1. 分区表：读取并验证分区表（pt_table_stuff），确定活动分区（active_id）支持 A/B 双分区设计，实现无缝固件更新和回滚处理分区条目，包括固件位置、大小、版本号
  2. 固件加载与启动：该程序会根据分区表加载固件到内存支持压缩固件：XZ 格式的解压blsp_boot2_check_xz_fw 多核支持： BLSP_BOOT2_CPU_GROUP_MAX 定义 CPU 数量
  3. 固件更新：OTA 更新：将新固件从临时分区复制到主分区防回滚（Anti-Rollback）：防止降级到不安全版本支持 USB/UART 烧录模式，对应代码：bflb_eflash_loader_main
  4. 安全：SHA-256 校验 具有固件完整性检查

您可以在开发板存在其他 App 的同时烧录该 bin ,这并不会覆盖掉你的程序，而是只为开发板更换 bootloader.
