“由于某种原因造成的记忆问题”使我颤抖。为了避免原因而不是问题的原因而进化的原因不是更安全吗？

  "Memory issues due to some reason" makes me shiver. Wouldn't it be safer to evolve the reason for issues to avoid the cause (and not the symptom)

鲍伯更新过程，他们写的是非常消耗内存，我们不想使用。
所以我们决定创建自己的引导加载组件。有可能使用CyPress创建者IDE吗？
如果是的话，你能提供一些输入给我吗？从哪里开始？



     以下为原文
  Bob update process that they have written is very memory consuming which we dont want to use.
    So we decided to go for creating our own bootloader component. is it possible to do it using cypress creator ide?
    If yes then can you please provide some inputs to me? from where to start?

链接DNA提供了一个相对完整的收集资料。要获得更多的信息，请在页面顶部使用“关键字搜索”，然后选择你感兴趣的信息。
内存消耗引导加载程序？为了实现非常基本的Bootloader函数，需要一些Flash，但我怀疑您是否可以通过编写代码来节省合理数量的ROM字节。
关于RAM：当引导加载程序将CONTOL传递到BootLoad中时，所有的RAM将被释放，因此这将不是问题。

  The links Dana provided are a relatively complete collection of the matter. To get much more information use the "Keyword Search" at top of this page and select the infos you're interested in.
    Memory consuming Bootloader? To implement the very basic bootloader functions some flash will be needed, no matter, but I question whether you will save a reasonable amount of rom-bytes by writing the code yourself.
    Concerning ram: when the bootloader passes contol to the bootloaded all ram in use will be freed, so that will not be an issue.

引导加载程序是与任何其他程序一样的程序。所以一个人写一封信并不复杂。我先看一下引导加载程序组件数据表。
基本上你只需要：
一个ToGOLE以决定何时启动应用程序以及何时引导（例如PIN）通信系统（用于下载新应用程序）闪存写入逻辑以将新的应用程序存储在存储器中以及PC应用程序用于将新应用程序发送到PSoC可引导加载应用程序T。HEN获得对Bootloader的引用，因此它知道它的大小（用于内存放置）。
Bootloader组件数据表也有通信协议的描述，所以您可以重用它。
顺便说一句：PSoC3引导装载器的大小只有2K，需要4字节的SRAM。你确信你会比这更好吗？它的通信部分需要更多的空间（数据表表示对于I2C需要额外的4K闪存和1.5 K RAM），并且你不会在那里节省很多。



     以下为原文
  A Bootloader is program as any other one. So it should be not to complicated to wrote one by yourself. I would start by looking at the bootloader component data sheet.
    Basically you just need:
   

    

• a toogle to decide when to start the application and when to bootload (e.g. a pin)    
  
• a communication system (for downloading the new application)    
  
• a flash write logic to store the new application in memory    
  
• and a PC application for sending the new application to the PSoC   
  

    The Bootloadable application then gets a reference to your bootloader, so it knows about its size (for memory placement).
    The bootloader component datasheets also has a description of the communication protocol, so you might reuse that.
    Btw: the PSoC3 bootloader is just 2k in size, and needs 4 bytes of sRAM. Are you sure you will be significantly better than that? Its the communication part which needs more space (the datasheets says for I2C one needs additional 4k flash and 1.5k RAM), and you won't probably save much there...

谢谢！
我们已经决定为PSoC 3设备创建我们自己的简单引导加载程序。
你能给我一些输入如何使用创建者IDE来设计吗？

  Thanks hli...
    We have tdecide to go for creating our own simple bootloader for psoc 3 device.
    Can you please give me some inputs how to design using creator ide.
     
    -Vijay

读取Bootloader组件数据表。它解释了这样的组件是如何工作的。我想你也应该读一下TRM，来学习写Flash记忆。其他任何事情都只是“正常”的编程，所以没有什么特别的地方可以告诉你。



     以下为原文
  Read the bootloader component data sheet. It explains how such a component works. I think you also should read the TRM, to learn about writing to flash memory. Anything else is just 'normal' programming, so there is nothing special to point you to.

但我觉得你还应该检查是否有可能去与现有的程序。你仍然没有说明你的实际问题是什么…



     以下为原文
  But I think you still should check wheter its possible to go with the existing bootloader. You still didn't state what your actual problem is...

实际上，我们对如何在当前引导程序中不可用的字段中更新应用软件有特定的要求。我们不能使用当前Bootloader所提供的更新工具。
是否有可能使用创建者IDE从头开始开发简单的引导加载程序组件？
如果是的话，你能给我们一些如何开始的投入吗？



     以下为原文
  actually we have a specific requirement about how update the application software  in the field which is not available in the current bootloader. we can not use updating facility given by current bootloader.
    is it possible to develop simple bootloader component from scratch using creator ide?
    if yes can you please give us some inputs of how to start?

哦，你以前没有提到过这样的要求。你说你有“记忆问题”…也许你可以问你的柏树代表，这些要求是否可以在下一个更新中的现有组件中实现？
是的，您可以在PSoC Creator中实现引导加载程序。我想事情没那么复杂。我已经给了你所有你需要的指针（已经两次了……）。
HLI



     以下为原文
  Oh, you didn't mention such specific requirements before. You said you had 'memory issues'... Maybe you can ask your Cypress representative whether these requirements could be implement in the existing component in one of the next updates?
    Yes, you can implement a bootloader in PSoC Creator. I guess its not that complicated. And I already gave you all the pointers you should need (twice already...).
     
    hli

你好，Hli，
我开始引用TRM文档。
但是，当为Bootloader组件创建库项目时，我不知道如何访问SFR。
因为我对PSoC设备很陌生，所以我不能把事情弄清楚。
你能指引我进入这个吗？
是否有任何使用SFR创建复合物的示例源代码？
-维杰



     以下为原文
  Hello Hli,
    I started referring TRM document.
    but i am not getting how to access SFR's when creating library project for bootloader component.
    As I am new to PSoC devices i am not getting things clearly.
    Can you please guide me into this?
    is there any sample source code with you which is creating compoent using SFR's?
     
    -Vijay

SFRs？你是说“特殊功能寄存器”吗？你想和他们做什么？（我猜你应该阅读PSoC3 TRM，和寄存器TRM更多的信息）。
我认为，不需要为引导加载程序创建一个新的组件或库。只要开发它作为一个普通的应用程序——它只是一个读取UART/USB /任何东西的东西，并把它存储到闪存中，并且能够运行这个代码。
在您的可引导加载应用程序中，然后引用为Bootloader应用程序创建的HEX文件，这样您的实际应用程序可以通过链接器放入正确的内存位置。



     以下为原文
  SFRs? Do you mean 'special function registers'? What do you want to do with them? (I guess you should read the PSoC3 TRM, and the registers TRM for more info on that).
    There is no need, I think, to create a new component or a library for the bootloader. Just develop it as a normal application - its just one that reads stuff over UART / USB / whatever and stores it into flash memory and is able to run this code.
    In your bootloadable application you then reference the hex file created for your bootloader app, so your real app can be put into the proper memory location by the linker.

请不要用新问题劫持不同主题的现有线程。如果你有一个新问题，请打开一个新的主题。这样，你会得到更好的答案，因为它变得更加透明。
谢谢！
