外部处理的话语（如果/ UART）

嗨对话支持/用户，

as you have written I can interpret that the (SUOTA enabled) application task running on the DA14580 is able to erase/write the external
SPI flash and also to send/trigger (via GTL layer/UART interface) some or all of the notification events/callbacks in the application user
section running on the external MCU. Am I right?

Thanks in advance for your answer.

嗨对话支持/用户，

在这里，我的最终测试结果：

1. I loaded in KEIL uVision IDE the靠近报告器外部模式located in the
   DA1458x_SDK_5.0.3\DA1458x_SDK\5.0.3\projects\target_apps\ble_examples\prox_reporter_extfolder.
   我修改了app_dis_sw_rev“0.0.1”在app.h标题文件中定义，我构建了项目的项目
   hex file that I renamed intoprox_reporter_ext.hex;
2. I ran the commandhex2bin prox_reporter_ext_0.hex生成相应的二进制文件prox_reporter_ext.bin;
3. I loaded in KEIL uVision IDE theProduction Testlocated in the
   da1458x_sdk_5.0.3 \ da1458x_sdk \ 5.0.3 \ projects \ target_apps \ prod_test \ prod_testfolder.
   I built the project producing bin fileprod_test_580.bin.;
4. I ran the commandmkimage single prox_reporter_ext.bin ble_580_sw_version_0.h prox_reporter_ext.jmg;
   这文件ble_580_sw_version_0.h.contains the following code lines:
   
#define DA14580_SW_VERSION "v_5.0.3.0"
#define DA14580_SW_VERSION_DATE "2016-05-19 16:01"
#define DA14580_SW_VERSION_STATUS "REPOSITORY VERSION"

5. I ran the commandmkimage single prod_test_580.bin ble_580_sw_version_1.h prod_test_580.jmg;
   现在file ble_580_sw_version_1.hcontains the following code lines:
   
#define DA14580_SW_VERSION "v_5.0.3.1"
#define DA14580_SW_VERSION_DATE "2016-05-19 16:04"
#define DA14580_SW_VERSION_STATUS "REPOSITORY VERSION"

6. 我加载并内置于Keil Uvision IDE中的二级Bootloadle项目
   C:\Users\monsminc\Documents\Dialog\DA1458x_SDK_5.0.3\DA1458x_SDK\5.0.3\utilities\secondary_bootloader那
   producing thesecondary_bootloader.hex;converted in binary format running the following command:
   hex2bin secodut_bootloader.hex.
7. I ran the command:
   mkimage multi spi secondary_bootloader.bin prox_reporter_ext.img 0x8000 prod_test_580.img 0x13000 0x1F000 da14580.bin
   要生成使用SmartSnippet（我没有启动的外部SPI Flash中刻录的双重图像
   图像是因为如果我正确理解了mkimage.exemakes automatically that operation);
8. I loaded and built in Microsoft Visual Studio C++ 2010 edition the projecthost_proxr.located
   in theDA1458x_SDK_5.0.3\DA1458x_SDK\5.0.3\projects\host_apps\windows\proximity\reporterfolder.
   I executed the resultinghost_proxr._sdk.exepassing it at the command line the COMM number
   of the Virtual Com Port seen when I attached the DA14580 Development Kit to my PC.
9. 接下来我安装在Nexux 9上运行Androind 6.0.1对话框Suota应用程序，通过USB将Nexus附加到PC
   and copying in theNexus 9\Internal storage\Suotafolder another img files result of previous experiments.
10. I launched the SUOTA app that successfully discovered my DA14580 Development Kit; then I made a connection to it;
    由此产生的下一个屏幕向我展示了我设置的确切固件修订版和软件版本。点击
    更新设备button of the SUOTA app let me obtained the next screen page where I selected the
    图像银行升级;我选择了第二个（图像库设置为2）告诉应用程序重新编程SPI
    flash memory mapped on the P0_0 (sck), P0_3 (cs), P0_5 (miso) and P0_6 (miso). The SUOTA correctly download the new
    image that I selected (I saw the downloading progress both on the screen app and in the console of the
    host_proxr.项目。
11. At the completion of download I answered no to the boot request and I disconnect from my development board;
    also I terminated the running console program of thehost_proxr.项目。这n I compared
    the choosen image present on the Nexus 9 (the one that I downloaded with the SUOTA app) against the file
    upgrade_image2.imggenerated by the console program (present in
    da1458x_sdk_5.0.3 \ da1458x_sdk \ 5.0.3 \ projects \ host_apps \ windows \ proximity \ eporer \ host_proxr_sdkfolder:
    它们的大小相同，仅在一个字节中（字节33th - 我使用cmp -l -b file1.img file2.img来比较两个图像）。
12. To be sure that the SUOTA app did not modify the external SPI Flash connected to the DA14580 I used the SmartSnippets
    to read its contents before and after the tests exposed above and compared against to see if they differ. They match.
    这意味着在外部模式（也称为完全嵌入），Suota应用程序允许更新固件
    of the external MCU, not the one burned in the SPI Flash.

So my question is: Is there a way to update also the SPI Flash from which the DA14580 boots in the presence of External Mode configuration?

Thank in advance for your attention

嗨对话支持，

Is there a documents in the User Manual or in the Application Note folders that explains the protocol the external Main MCU and theflash_programmer
both must implement and to follow to exchange data and to correctly program the external SPI Flash. I know that I can obtain it making the reverse engineering of the
flash_programmer一篇的代码项目，但我认为如果你能把我指向官方文件，那就更好了..

Thanks in advance for your reply
