XIP FLASH 设备
|
||||
=========================
|
||||
|
||||
简介
|
||||
------------------------
|
||||
|
||||
XIP：eXecute In Place，即芯片内执行，指应用程序可以直接在 flash 闪存内运行，不必再把代码读到系统 RAM 中。所谓片内执行并不是说程序在存储器内执行，CPU的基本功能是取指、译码、执行，存储器访问，写回。通常我们使用 Nor Flash，Nor Flash能在芯片内执行，指的是 CPU 能够直接从Nor flash 中取指令，供后面的译码器和执行器来使用。
|
||||
|
||||
博流系列芯片拥有 XIP FLASH 控制器，并且支持内存映射，BL702/BL704/BL706 的逻辑地址为 0x23000000,最大可支持 8M 的 nor flash。不仅如此，映射的实际物理 flash 地址是可以修改的，举例来说，假设一个 nor flash 大小为 1M，如果应用程序烧录在 flash 物理地址 0，那么就可以将逻辑地址映射到 0 地址，如果应用程序烧录在 flash 物理地址 x，那么就可以将逻辑地址映射到 x 地址，而逻辑地址可以保持不变，一直是 0x23000000，省去了修改 ld 文件的麻烦。
|
||||
|
||||
下图演示三块应用程序映射地址分布:

LowPower 低功耗评估
|
||||
Power Management
|
||||
=========================
|
||||
|
||||
简介
|
||||
------------------------
|
||||
本 demo 主要演示 bl 系列 mcu 低功耗性能。具体低功耗介绍请参考 `BL702/704/706 参考手册 <https://dev.bouffalolab.com/media/upload/doc/BL702_BL704_706_RM_zh_CN_1.1.pdf>`_。
|
||||
|
||||
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
|
||||
低功耗模式：
|
||||
|
||||
1. 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。
|
||||
- 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。
|
||||
|
||||
2. 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。
|
||||
- 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。
|
||||
|
||||
3. 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。
|
||||
- PDS 模式: 根据不同的模式关闭不同的电源域，当关闭了 CPU 电源域时，ITCM，DTCM RAM 不可使用，只有 64K 的 OCRAM 可以使用。
|
||||
|
||||
4. 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。
|
||||
- HBN 模式: 根据不同的模式关闭不同的电源域，ITCM，DTCM OCRAM RAM 无法使用，在 hbn0 下位于 AON 域的 4K RAM 可以使用，其他 hbn 模式下 4K RAM 也不可使用。
|
||||
|
||||
|
||||
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:
|
||||
演示内容：
|
||||
|
||||
+------------+------------+------------+---------------------+---------------------------+
|
||||
|模式 |参考电流 |对应基础模式|唤醒源 |备注 |
|
||||
+============+============+============+=====================+===========================+
|
||||
|Running |5.68 mA |Run | |所有外设时钟都打开 |
|
||||
+------------+------------+------------+---------------------+---------------------------+
|
||||
|WFI |3.14 mA |WFI |任意中断 |除串口外，其它外设时钟关闭 |
|
||||
+------------+------------+------------+---------------------+---------------------------+
|
||||
|PDS |10 uA |PDS 31 |内部RTC/引脚中断 |64K OCRAM保存数据 |
|
||||
+------------+------------+------------+---------------------+---------------------------+
|
||||
|HBN |1 uA |HBN 1 |内部RTC/引脚中断 |4K AON RAM保存数据 |
|
||||
+------------+------------+------------+---------------------+---------------------------+
|
||||
- pds3 使用 gpio10 外部中断下降沿唤醒
|
||||
- pds31 使用 pds 唤醒脚 (gpio6) 唤醒
|
||||
- pds31 使用 pds timer 唤醒
|
||||
- hbn0 使用 acomp (gpio11) 唤醒
|
||||
- hbn1 使用 rtc 唤醒
|
||||
- hbn2 使用 hbn 唤醒脚 (gpio12) 唤醒
|
||||
|
||||
.. note:: 高级别的唤醒源可以唤醒低级别的功耗模式，比如 hbn 唤醒脚可以唤醒所有的低功耗模式。
|
||||
|
||||
|
||||
上表中的参考电流是通过示例固件测试得出的。符合 bl70x 系列 MCU 的 spec 的描述，run wfi pds hbn 四种等级的定义简化了原先的 hbn level 以及 pds level 的设定。
|
||||
准备工具
|
||||
-----------------------
|
||||
|
||||
见 bl702_bl704_bl706_DS_EN_Combo_1.9.pdf page 28

|
||||
|
||||
|
||||
**低功耗示例测试方法**
|
||||
------------------------
|
||||
|
||||
**编译低功耗示例代码**
|
||||
^^^^^^^^^^^^^^^^^^^^^^^^
|
||||
|
||||
在工程目录下键入 ``make APP=lowpower_test SUPPORT_SHELL=y BOARD=bl706_lp`` 完成低功耗示例 bl706 的编译。或者直接使用 CDK 工程，完成编译下载
|
||||
您可以参考本文档《快速开发指南》来获取更多编译烧写的信息。
|
||||
|
||||
当编译并烧写成功后，连接串口到电脑端，并复位芯片，Xshell 会出现如下图所示的页面。
|
||||
|
||||
.. figure:: img/xShell_lowpower.png
|
||||
|
||||
.. note::当前 demo 仅仅只是测试三种低功耗模式的使用，如果需要测试达到手册中描述的，需要很多步骤，具体步骤请与我们联系。
|
||||
|
||||
**准备低功耗测试所需的硬件环境**
|
||||
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
||||
|
||||
- 可以串联电流表到电源端的电路板
|
||||
- 电流表
|
||||
- 一台 PC 主机（运行 Windows 或者 Linux 系统）
|
||||
- TTL 转 USB
|
||||
|
||||
如下图所示，将电流表串联进入 bl706 模组的供电线路，通过 PC 端的串口调试助手软件，下发不同的低功耗指令，使得 bl706 进入对应的低功耗模式
|
||||
观察电流表示值，完成评估。
|
||||
- pc控制端使用串口终端软件：xshell 或者 mobaxterm
|
||||
- 可以串联电流表到电源端的电路板
|
||||
- 电流表
|
||||
- TTL 转 USB
|
||||
- 滑动变阻器
|
||||
|
||||
.. figure:: img/lowpower_arch.png
|
||||
|
||||
**使用 Xshell 开始评估低功耗性能**
|
||||
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
||||
用户可以通过在 Xshell 输入下述指令，进入对应的低功耗模式。
|
||||
|
||||
``run``
|
||||
硬件连接
|
||||
-----------------------------
|
||||
|
||||
- 复位芯片之后，默认进入 run 模式，没有进入任何低功耗模式，芯片实际在运行 while(1); 语句。
|
||||
本 demo 基于 BL706_LP 开发板，连接方式如下
|
||||
|
||||
``wfi``
|
||||
::
|
||||
|
||||
GPIO function GPIO pin
|
||||
----------------------------------
|
||||
PDS_WAKEUP <--> GPIO6
|
||||
EXTI <--> GPIO10
|
||||
ADC <--> GPIO11
|
||||
HBN_WAKEUP <--> GPIO12
|
||||
UART0_TX <--> GPIO14
|
||||
UART0_RX <--> GPIO15
|
||||
|
||||
软件实现
|
||||
-------------------------
|
||||
|
||||
软件基于 shell 进行调试，如何注册 shell 命令这里不再说明。
|
||||
|
||||
PDS 模式
|
||||
^^^^^^^^^^^^^^^^
|
||||
|
||||
- 软件代码见 ``examples/pm/pds_mode_wakeup``
|
||||
|
||||
.. code-block:: C
|
||||
:linenos:
|
||||
|
||||
#define CONFIG_GPIO6_FUNC GPIO_FUN_WAKEUP
|
||||
|
||||
- pds 唤醒脚配置，pds3 和 pds31 使用，见 ``bsp/board/bl706_lp/pinmux_config.h``
|
||||
|
||||
.. code-block:: C
|
||||
:linenos:
|
||||
|
||||
#define CONFIG_GPIO10_FUNC GPIO_FUN_GPIO_EXTI_FALLING_EDGE
|
||||
|
||||
- 外部中断引脚配置，pds3 使用，见 ``bsp/board/bl706_lp/pinmux_config.h``
|
||||
|
||||
.. code-block:: C
|
||||
:linenos:
|
||||
|
||||
#define CONFIG_GPIO12_FUNC GPIO_FUN_WAKEUP
|
||||
|
||||
- hbn 唤醒脚配置，pds3 和 pds31 使用，见 ``bsp/board/bl706_lp/pinmux_config.h``
|
||||
|
||||
|
||||
- 进入 wfi 模式，后面不加任何参数，进入之后，CPU 处于 clock gating 状态，降低功耗
|
||||
- 进入 wfi 模式后，任何中断会唤醒，例如 uart 中断。在 Xshell 中敲击回车会触发 BL706 UART RX 中断，因此可以通过此方法唤醒 wfi 低功耗模式。

- 注册进入 hbn0、hbn1、hbn2 的命令
|
||||
|
||||
|
||||
- pds 可以选择带一个 sleeptime 的参数，决定其内部 RTC 唤醒时间。如果指令不带此参数，那么默认不使用 RTC 内部唤醒，目前的固件仅支持上电复位唤醒。
|
||||
- 如果指令包含 sleeptime 参数，pds 将会在``sleeptime * clock_period`` 的时刻被唤醒，表现为复位芯片，重新打印起始报文。
|
||||
- 进入低功耗模式后，RTC 的时钟是 32K，因此 sleeptime 为 32768 时，表现为睡眠 1S 后唤醒。

||||

|
||||
实验现象
|
||||
-----------------------------
|
||||
|
||||
- 首先唤醒脚唤醒方式默认均为下降沿唤醒，所以需要将 GPIO6、GPIO10、GPIO12 引脚外接电阻到 3.3V。
|
||||
- acomp 变化电压阈值在 1.2375V，所以需要使用滑动电阻器，调整到 1.2375V（0.375VBAT）后再使用。
|
||||
- 打开终端，并按下 TAB 键可以列出命令。
|
||||
- 输入需要执行命令回车即可运行。

MSC - U 盘升级
|
||||
====================
|
||||
|
||||
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。
|
||||
|
||||
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。
|
||||
|
||||
MSC 协议介绍参考 `USB 官方文档 <https://www.usb.org/documents>`_。
|
||||
|
||||
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。
|
||||
|
||||
.. figure:: img/usb_msc.png
|
||||
|
||||
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：

- 配置 GPIO15 作为输入模式，默认拉低，拉高进入 u 盘升级。
|
||||
- 如果 GPIO15 为高，则进入 u 盘 升级程序。
|
||||
- 如果 GPIO15 为低，则表示不需要升级直接进入 app，此时需要修改内存映射地址，将逻辑地址映射的物理地址（flash offset ）从 0x2000 改成实际 app 存储在 flash 的地址为：FLASH_ADDR + 10 * BLOCK_SIZE。
|
||||
- ``hal_jump2app`` 中对物理地址进行了判断，bootloader 程序预留 48K，物理地址小于 4M。

<p>XIP：eXecute In Place，即芯片内执行，指应用程序可以直接在 flash 闪存内运行，不必再把代码读到系统 RAM 中。所谓片内执行并不是说程序在存储器内执行，CPU的基本功能是取指、译码、执行，存储器访问，写回。通常我们使用 Nor Flash，Nor Flash能在芯片内执行，指的是 CPU 能够直接从Nor flash 中取指令，供后面的译码器和执行器来使用。</p>
|
||||
<p>博流系列芯片拥有 XIP FLASH 控制器，并且支持内存映射，BL702/BL704/BL706 的逻辑地址为 0x23000000,最大可支持 8M 的 nor flash。不仅如此，映射的实际物理 flash 地址是可以修改的，举例来说，假设一个 nor flash 大小为 1M，如果应用程序烧录在 flash 物理地址 0，那么就可以将逻辑地址映射到 0 地址，如果应用程序烧录在 flash 物理地址 x，那么就可以将逻辑地址映射到 x 地址，而逻辑地址可以保持不变，一直是 0x23000000，省去了修改 ld 文件的麻烦。</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。

<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>
