kaa示例太大而无法放入esp8266 [英] kaa example too big to fit esp8266
问题描述
I'm experimenting with the kaa IoT platform on an ESP8266 and have followed this guide. I've set up a new build environment in an Lubuntu virtual box and the build appears to run ok however it complains of a lack of code space (see below).
似乎ESP8266无法处理加密，因此我确保使用"-DWITH_ENCRYPTION = OFF"在cmake文件中将其关闭，但这无济于事.奇怪的是，该构建似乎仍然提到加密，因此也许我没有正确禁用它.
It seems that the ESP8266 can't handle encryption so I made sure that was turned off in the cmake file using "-DWITH_ENCRYPTION=OFF" but that does not help. Weirdly, the build still seems to mention encryption so perhaps I've not disabled it properly.
当我将目标指定为esp8266时，我不明白为什么会提到内置目标mbedtls".
I don't understand why it mentions "Built target mbedtls" when I've specified the target as esp8266.
无论如何，这是构建输出，以防有人可以帮助我:-)
Anyway, here's the build output in case anyone can help me :-)

推荐答案
当根据您参考的教程首先使用自定义SDK构建示例应用程序时，我遇到了完全相同的问题.
I had the exact same problem when first building the sample app with a custom SDK according to the tutorial you referenced.
首先，内置目标mbedtls 是指make文件指定的构建目标，而不是您的目标平台.如开始所见， KAA_PLATFORM = esp8266 显示正确的值.稍后，make也将编译正确的文件(例如:[ 38%] Building C object libs/kaa/CMakeFiles/kaac.dir/src/kaa/platform-impl/esp8266/logger.c.obj).没关系.
First of, the Built target mbedtls refers to the build targets specified by the make file, not your target platform. As you can see in the beginning, the KAA_PLATFORM = esp8266 shows the correct value. Later on, make compiles the correct files as well (for example: [ 38%] Building C object libs/kaa/CMakeFiles/kaac.dir/src/kaa/platform-impl/esp8266/logger.c.obj). This should be fine.
在您的版本中禁用了加密.否则，它将在用户扩展启用下方打印 ENCRYPTION ENABLED .
Encryption is disabled in your build. Otherwise it would print ENCRYPTION ENABLED below USER EXTENSION ENABLED.
以下是几种可能的解决方案:
Here are a couple of possible solutions:
对我来说，一个问题是必须调整链接文件 eagle.app.v6.ld (应位于项目根目录的 ld 文件夹中)以便将部分代码从RAM移到ROM.
One problem for me was that the linker file eagle.app.v6.ld (which should be in the folder ld in your project's root) had to be adjusted so that some parts of the code are moved from RAM to ROM.
I use the linker file from the Kaa sample app and refer to that in the following explanation.
在.text : ALIGN(4)部分中，找到包含以下内容的行:
In the section .text : ALIGN(4), find the line containing:
*( .literal .text .literal.* .text.* .stub .gnu.warning .gnu.linkonce.literal.* .gnu.linkonce.t.*.literal .gnu.linkonce.t.*)
从此处删除.literal.* .text.*部分，并将其移至.irom0.text : ALIGN(4)，方法是在_irom0_text_start = ABSOLUTE(.);之后添加以下行:
Remove the sections .literal.* .text.* from there and move them to .irom0.text : ALIGN(4) by adding the following line after _irom0_text_start = ABSOLUTE(.);:
*(.literal.* .text.*)
现在，所有以.literal.和.text.开头的部分都位于ROM中.这是一种蛮力，因为无论* .a模块(由.irom0.text : ALIGN(4)部分中的下面的行定义)如何，所有此类的部分都将移至ROM.它可能有一些我还没有经历过的并发症.肯定有优化链接器映射的空间.
Now all sections starting with .literal.and .text. are located in the ROM. This is sort of brute force because regardless of the *.a module (as defined by the lines below that in the section .irom0.text : ALIGN(4)), all sections of this type are moved to ROM. It might have some complications which I did not yet experience. There is definitely room to optimize the linker mapping.
对我来说，这在RAM中节省了大量内存，并且程序可以正确编译，链接和运行.
For me this saved a huge amount of memory in RAM and the program compiled, linked and ran correctly.
使用cmake配置内部版本时，可以将不同的参数传递给cmake以打开或关闭扩展名(例如，-DWITH_EXTENSION_PROFILE=OFF以关闭配置文件).
When configuring the build with cmake, you can pass different arguments to cmake to turn extensions on or off (e.g. -DWITH_EXTENSION_PROFILE=OFF to turn off profiles).
您的情况下，似乎启用了以下扩展名:
In your case, the following extensions seem to be enabled:
- 已启用引导程序
- 已启用个人资料
- 启用用户扩展
根据我的经验，某些扩展只是很大，可以编译到最终映像中.我成功包含了 Configuration 和 Logging 扩展.添加任何其他扩展都会导致RAM溢出.
In my experience, some extensions are just to big to be compiled into the final image. I successfully included the Configuration and Logging extensions. Adding any other extensions has lead to an overflow of the RAM.
确保仅启用端点SDK真正需要的那些扩展.如果仍然失败，请尝试关闭所有扩展，并逐步启用它们，以查看哪些扩展失败.
Make sure to enable only those extensions which are really needed by your endpoint SDK. If it still fails, try to turn all extensions off and enable them step-by-step to see which ones fail.
以下命令将列表打印到文件 listing.txt 中，其中详细列出了将哪些代码映射到哪个部分.这可能有助于找出代码的哪些部分在RAM和ROM中使用最多的内存. (将 name_of_your_image 替换为make命令生成的图像的实际名称)
The following command prints out a list to the file listing.txt detailing which code is mapped to which section. It might help finding out which parts of the code use the most memory in RAM and ROM. (replace name_of_your_image with the actual name of the image generated by the make command)
xtensa-lx106-elf-objdump -x name_of_your_image > listing.txt
xtensa-lx106-elf-objdump -x name_of_your_image > listing.txt
