用户可以配合 Dev Cube 图形界面烧写软件，将已有的 boot2_iap.bin 文件烧录进目标板，烧录
|

一次之后，就可以通过 IAP 功能，在线更新用户代码。</p>

<p>bl_mcu_sdk 开源了 boot2_iap 的软件源码，用户可以到 examples/boot2_iap 查阅代码，并完成编译烧写。编译烧写过程可以参考《快速开发指南》介绍。</p>

<p>博流系列芯片拥有丰富的低功耗特性，以适配不同的低功耗应用场合。为了方便用户快速的评测使用 bl 系列 MCU 低功耗性能 bl_mcu_sdk 提供了一套抽象的低功耗接口，将低功耗等级分为四个等级，分别为</p>
|

<ol class="arabic simple">
|
||||
<li><p>Running : Running 为 CPU 正常运行时的功耗，由客户应用代码执行的功能决定功耗。</p></li>
|
||||
<li><p>WFI ：WFI 模式，CPU 的 clock 处于被 Gating 状态，CPU 停止运行，当用户退出WFI模式的时候程序将会继续运行。</p></li>
|
||||
<li><p>PDS : PDS 模式，关闭了芯片上大多数电源域，同时关闭了 CPU，和 CPU 处于同一个电源域的 ITCM，DTCM 等 RAM 不可使用，只有 64K 的 OCTAM 可以保存数据，可以通过内部 RTC 进行唤醒，或者使用 GPIO 引脚(在 GPIO 电源域没有关闭的情况下)唤醒。</p></li>
|
||||
<li><p>HBN : HBN 模式，关闭了芯片上绝大多数电源域，关闭了 CPU 以及 64K OCRAM，只有位于 AON 域的 4K RAM 可以保存数据，可以通过内部 RTC 进行唤醒，或者使用特定的唤醒引脚(位于 AON 域的引脚)唤醒。</p></li>

<p>bl_mcu_sdk 提供了一个简单的低功耗参考示例(bl_mcu_sdk examples/power/lowpower_test/)，旨在帮助用户快速评估低功耗功能，如果需要进一步适配自身的低功耗场景，采取不同的低功耗策略，请查阅相关 datasheet 或者寻找 Boufflao Lab 的技术支持。

在该示例中，外设及 CPU 的时钟选择均是晶振 32M。基于该示例的功耗测量结果如下表所示:</p>

<p>本 demo 主要演示使用 usb 将 xip flash 模拟成 u 盘设备，将其作为一个 BootLoader 使用，用来升级固件。</p>
|
||||
<p>USB大容量存储设备类（The USB mass storage device class）是一种计算机和移动设备之间的传输协议，它允许一个通用串行总线（USB）设备来访问主机的计算设备，使两者之间进行文件传输。</p>
|
||||
<p>MSC 协议介绍参考 <a class="reference external" href="https://www.usb.org/documents">USB 官方文档</a>。</p>
|
||||
<p>bootloader 我们将其编译后烧录在 flash 0x2000 开始的物理地址，工具默认也是这个地址。</p>

|

<p>我们使用 flash 物理地址 0x0000c000 (48K) 开始的地方，用来模拟 u 盘，u 盘大小为 256K（64 个扇区，每个扇区 4KB ），根据文件系统格式，可以知道，数据的地址在 u 盘的第 10 个扇区（0x16000），也即 APP 的入口地址。BootLoader 与 APP 分区表如下：</p>
