|
||
<p>Dev Cube 是博流提供的芯片集成开发工具，包含IOT程序下载、MCU程序下载和RF性能测试三种功能。本文档主要介绍IOT和MCU程序下载相关配置，RF性能测试请参考《射频性能测试使用手册》。</p>
|
||
<p>Dev Cube 提供用户下载程序的功能，并且支持时钟、flash等参数配置，用户可根据自身需求决定是否对程序进行加密、添加签名、更换程序启动时的信息文件、用户资源文件、分区表等功能配置。</p>
|
||
<p>具体的功能如下：</p>
|
||
<ol class="arabic simple">
|
||
<li><p>支持IOT应用程序和MCU应用程序的下载</p></li>
|
||
<li><p>支持多种型号Flash 的擦、写、读；</p></li>
|
||
<li><p>可将各类文件下载到Flash并验证、回读；</p></li>
|
||
<li><p>下载通讯接口支持 UART 和 JLink 两种方式。</p></li>
|
||
</ol>
|
||
<p>用户可以通过 <a class="reference external" href="https://dev.bouffalolab.com/download">Bouffalo Lab Dev Cube</a>，获取最新版本的Dev Cube。

|
||
<p>如果只下载应用程序无法使芯片正常工作，必须要将引导信息下载到指定位置。引导信息包含对PLL、Boot、Flash等的配置；固件是用户自己编写的应用程序。</p>
|
||
<p>以单核下载为例：根据需求选择对应的参数,将对PLL、Flash等配置的信息烧录到Bootinfo Addr对应的地址中，将应用程序经过编译后的bin文件烧录到Image Addr对应的地址中。</p>

<li><p>MFG Bin：选择MFG文件</p></li>
|

<li><p>AES-Encrypt：如果使用加密功能，需要将AES-Encrypt选项选中，并在旁边的文本框中输入加密所使用的Key和IV。输入的是十六进制对应的“0”~“F”，一个Byte由两个字符构成，所以Key和IV分别要求输入32个字符。需要注意的是IV的最后8个字符（即4Bytes）必须全为0</p></li>
