Hardware Notes
|
||||
==============
|
||||
|
||||
This file contains a compilation of various pieces of information about the
|
||||
BL602's hardware (e.g. core, peripherals, debug, memory map), gathered from
|
||||
this repository and around the internet. This is the best we can do in lieu of
|
||||
a proper Technical Reference Manual, which has not yet been released as of
|
||||
this writing.
|
||||
|
||||
Contributions welcome!
|
||||
|
||||
CPU Core
|
||||
--------
|
||||
According to [soc602_reg.svd][2], the BL602 contains a RISC-V RV32IMAFC core.
|
||||
Interestingly, the [datasheet][1] and online spec sheets from Bouffalo Lab
|
||||
never mention RISC-V, simply calling the core a "32-bit RISC CPU."
|
||||
|
||||
CNX Software [claims][5] that the core is a [SiFive E24][6]. Although this
|
||||
claim is unsourced, information in the datasheet seems to corroborate it. The
|
||||
datasheet claims that the CPU achieves a Dhrystone score of 1.46 DMIPS/MHz and
|
||||
a CoreMark score of 3.1 CoreMark/MHz. These numbers exactly match what SiFive
|
||||
advertises for the E24. Similarly, the set of RISC-V extensions matches, as
|
||||
does the pipeline length (3-stage) and number of breakpoints/watchpoints (4).
|
||||
|
||||
The BL602 appears to diverge from the reference E24 implementation in its
|
||||
memory map, however: its peripherals are mapped starting at `0x4000_0000`,
|
||||
whereas SiFive's [E24 Manual][7] has a memory map placing peripherals at
|
||||
`0x2000_0000`. Likewise, the BL602 maps its memories at `0x2000_0000` but the
|
||||
E24 reference design maps them at `0x6000_0000`. Finally, the BL602's TCMs are
|
||||
differently-mapped, differently-named (TCM vs TIM), and differently-sized
|
||||
(48KiB vs 32KiB) from the reference E24 ones. SiFive does claim that the memory
|
||||
map and TIM sizes are customizable, though, so none of these differences are
|
||||
strong evidence against the core being an E24.
|
||||
|
||||
[clic.h][4], which is part of the BL602's register definition headers, appears
|
||||
to be a SiFive-authored file (see the include guard), and its addresses match
|
||||
the E24 reference. I think this is one of the clearest pieces of evidence for
|
||||
the core being SiFive IP.
|
||||
|
||||
Memory Map
|
||||
----------
|
||||
The [datasheet][1] contains a memory map, as does [soc602_reg.svd][2] and
|
||||
[bl602.h][3]. As mentioned above, [clic.h][4] also contains part of the map. I
|
||||
have attempted to synthesize information from all these sources into a single
|
||||
unified table. I make no guarantees to the accuracy of this table.

|
||||
| `0x4202_0000` | `0x4203_BFFF` | Wireless RAM (datasheet disagrees on base)|
|
||||
|
||||
(Peripherals in *`italics`* are present in the SVD but not the datasheet.)
|
||||
|
||||
The datasheet claims that the system has 276KiB of RAM, and indeed that is the
|
||||
number we get by adding up 64KiB of main RAM, 112KiB of wireless RAM, 48KiB of
|
||||
instruction TCM, 48KiB of data TCM, and 4KiB of deep sleep retention RAM.
|
||||
|
||||
As noted in the table, the wireless RAM address is ambiguous. bl602.h says it's
|
||||
`0x4202_0000`, but the datasheet says it's `0x4203_0000`. I can only assume one
|
||||
of them is a typo, and my guess is that it's the one that isn't code.
|
||||
|
||||
Interestingly, bl602.h defines three extra "remap" mappings, labeled REMAP0,
|
||||
REMAP1, and REMAP2, in addition to the ranges in the table above for each of
|
||||
flash XIP, wireless RAM, and the TCMs. I have not found any register that looks
|
||||
like a remapping control, so I'm not sure what this is about. The remap base
|
||||
addresses are as follows:
|
||||
|
||||
| Memory | "Normal" base | REMAP0 base | REMAP1 base | REMAP2 base |
|
||||
|--------|---------------|---------------|---------------|---------------|
|
||||
| XIP | `0x2300_0000` | `0x3300_0000` | `0x4300_0000` | `0x5300_0000` |
|
||||
| WRAM | `0x4202_0000` | `0x2202_0000` | `0x3202_0000` | `0x5202_0000` |
|
||||
| TCM | `0x2200_8000` | `0x3200_8000` | `0x4200_8000` | `0x5200_8000` |

<h2><span class="section-number">3.1. </span>概述<a class="headerlink" href="#id1" title="永久链接至标题">¶</a></h2>
|
||||
<p>linux下有强大的shell工具，可以让用户和片上系统进行交互，而在传统的单片机系统中，用户往往需要自行实现一套类似的交互工具。AliOS-Things原生带有一套名为cli（command-line
|
||||
interface）的命令行交互工具，在提供基本的系统交互命令的基础上，也支持用户自定义命令。我们已经将其移植到我们到系统中，
|
||||
同时对其做出了很多完善， 下面将介绍如何使用cli命令并执行</p>

<div class="section" id="id2">
|
||||
<h2><span class="section-number">3.2. </span>示例代码<a class="headerlink" href="#id2" title="永久链接至标题">¶</a></h2>
|
||||
<p>用户在只需在程序中调用<code class="docutils literal notranslate"><span class="pre">test_cli_init()</span></code>接口之后，就可以在shell中<code class="docutils literal notranslate"><span class="pre">test</span></code>,就可以打印<code class="docutils literal notranslate"><span class="pre">hello</span> <span class="pre">world.</span></code>如下图所示</p>
|

<div class="highlight-default notranslate"><div class="highlight"><pre><span></span><span class="c1">#</span>
|

<span class="c1">#</span>
|

<span class="c1"># test</span>

<p>Yloop 是AliOS
|
||||
Things的异步事件框架。Yloop借鉴了，libuv及嵌入式业界常见的event
|
||||
loop，综合考虑使用复杂性，性能，及footprint，实现了一个适合于MCU的事件调度机制。我们移植了相关的插件。其主要优势是所有的处理都是在主任务中执行的，不需要额外的创建任务，从而节省内存使用。同时，由于所有处理都是在主任务进行，不需要复杂的互斥操作。</p>

Things的程序入口application_start

Things自带的协议栈又暴露一个特殊的eventfd接口，Yloop利用此接口把VFS的设备文件，和eventfd关联起来，实现了对整个系统的事件的统一调度。</p>

<h2><span class="section-number">2.1. </span>Dev Cube 简介<a class="headerlink" href="#dev-cube" title="永久链接至标题">¶</a></h2>
|
||||
<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>
|

<h2>总览<a class="headerlink" href="#id1" title="永久链接至标题">¶</a></h2>
|

<p>AES是一种对称加密算法，它的相关概念在此不赘述，本文档主要介绍AES-GCM的原理和实现。</p>
|
||||
<p>GCM ( Galois/Counter Mode) 指的是该对称加密采用Counter模式，并带有GMAC消息认证码。
|
||||
在详细介绍AES-GCM之前，我们先了解一些相关概念。</p>

||||

|

<div class="section" id="ctr-counter">
|
||||
<h2>CTR（CounTeR）<a class="headerlink" href="#ctr-counter" title="永久链接至标题">¶</a></h2>
|
||||
<blockquote>
|
||||
<div><p>在CTR模式下，我们对一个逐次累加的计数器进行加密，用加密后的比特序列与明文分组进行异或得到密文。过程如下图：</p>
|
||||
<blockquote>
|
||||
<div><div class="figure align-default">
|
||||
<img alt="" src="../../_images/image12.png" />
|
||||
</div>
|
||||
</div></blockquote>
|
||||
</div></blockquote>
|
||||
<p>其中， IV为初始化向量，Ek表示ECB文本加密，PT表示输入的明文，CT表示输出的密文。</p>
|
||||
<p>在BL602中，我们可以直接使用硬件完成CTR算法，即设置key密钥后，输入IV以及需要加密的明文，硬件会自动完成累加计数加密并输出密文。</p>
|
||||
<p>CTR模式的优点是：
|
||||
1）支持加解密并行计算，可事先进行加解密准备；
|
||||
2）错误密文中的对应比特只会影响明文中的对应比特。
|
||||
但是它不能提供密文消息完整性校验的功能。</p>
|
||||
</div>
|
||||
<div class="section" id="mac-message-authentication-code">
|
||||
<h2>MAC（Message Authentication Code）<a class="headerlink" href="#mac-message-authentication-code" title="永久链接至标题">¶</a></h2>
|
||||
<p>想要校验消息的完整性，必须引入另一个概念：消息验证码。消息验证码是一种与秘钥相关的单项散列函数，过程如下图所示：</p>
|
||||
<blockquote>
|
||||
<div><div class="figure align-default">
|
||||
<img alt="" src="../../_images/image21.png" />
|
||||
</div>
|
||||
</div></blockquote>
|
||||
<p>密文的收发双发需要提前共享一个秘钥。密文发送者将密文的MAC值随密文一起发送，密文接收者通过共享秘钥计算收到密文的MAC值，
|
||||
这样就可以对收到的密文做完整性校验。当篡改者篡改密文后，没有共享秘钥，就无法计算出篡改后的密文的MAC值。</p>
|
||||
</div>
|
||||
<div class="section" id="gmac-galois-message-authentication-code-mode">
|
||||
<h2>GMAC（Galois message authentication code mode）<a class="headerlink" href="#gmac-galois-message-authentication-code-mode" title="永久链接至标题">¶</a></h2>
|
||||
<p>对应到上图中的消息认证码，GMAC就是利用伽罗华域(Galois Field，GF，有限域)乘法运算来计算消息的MAC值。
|
||||
假设秘钥长度为128bits, 当密文大于128bits时，需要将密文按128bits进行分组。应用流程如下图：</p>
|
||||
<blockquote>
|
||||
<div><div class="figure align-default">
|
||||
<img alt="" src="../../_images/image3.png" />
|
||||
</div>
|
||||
</div></blockquote>
|
||||
<p>其中，msg为需要验证的消息，Mh表示在有限域上做乘法运算，MAC即为生成的验证码。</p>
|
||||
<p>在BL602中，我们可以直接使用硬件完成GMAC验证。</p>
|
||||
</div>
|
||||
<div class="section" id="gcm-galois-counter-mode">
|
||||
<h2>GCM（ Galois/Counter Mode )<a class="headerlink" href="#gcm-galois-counter-mode" title="永久链接至标题">¶</a></h2>
|
||||
<p>GCM中的G就是指GMAC，C就是指CTR。于是将CTR算法加上GMAC验证就是AES-GCM模式了。过程如下图所示：</p>
|
||||
<blockquote>
|
||||
<div><div class="figure align-default">

<div class="section" id="id2">
|

<h2>使用步骤<a class="headerlink" href="#id2" title="永久链接至标题">¶</a></h2>
|
||||
<p>1.首先进行初始化.调用hal_hbnram_init(void)，进行初始化hbnram。如果是断电重启，则会清空hbnram,如果是不断点的reboot,则仅校验数据。
|
||||
2.hal_hbnram_alloc(const char <a href="#id3"><span class="problematic" id="id4">*</span></a>key, int len),key 必须是const char 类型的字符串，且必须小于4个字符。len是要申请的内存的长度。
|
||||
3.hal_hbnram_buffer_set(const char <a href="#id5"><span class="problematic" id="id6">*</span></a>key, uint8_t <a href="#id7"><span class="problematic" id="id8">*</span></a>buf, int length)；把数据一次写入申请的buff.
|
||||
4.hal_hbnram_buffer_get(const char <a href="#id9"><span class="problematic" id="id10">*</span></a>key, uint8_t <a href="#id11"><span class="problematic" id="id12">*</span></a>buf, int length)；把数据一次从buff读出
|
||||
5.hal_hbnram_handle_get_fromkey(const char <a href="#id13"><span class="problematic" id="id14">*</span></a>key, hbnram_handle_t <a href="#id15"><span class="problematic" id="id16">*</span></a>handle);如果需要流读写，需要首先根据key，获取hanlde.
|
||||
6.hal_hbnram_copy_from_stream(hbnram_handle_t <a href="#id17"><span class="problematic" id="id18">*</span></a>handle, uint8_t <a href="#id19"><span class="problematic" id="id20">*</span></a>buf, int len);流读出
|
||||
7.hal_hbnram_copy_to_stream(hbnram_handle_t <a href="#id21"><span class="problematic" id="id22">*</span></a>handle, uint8_t <a href="#id23"><span class="problematic" id="id24">*</span></a>buf, int len); 流写入</p>
|
||||
<p>具体使用方式参考 sdk_app_hbnram下的demo.c</p>
|
||||
<p>应用实例:
|
||||
将工程sdk_app_hbnram 编译，烧写进入板子。重启板子。</p>
