如何把Flash更新实用程序变成RAM

GCClinker的文件是：http://ftp.gnu.org/old-gnu/manuals/ld-2.9.1/html_node/ld_21.html
但是，当我刚刚投入：
数据：对齐（8）{ __cy_region_start_data =。；保持（*（，JCR））*（。了PLT）*（*（了）。shdata）*（。数据。数据。*。GNU。linkonce D. *）cyflash。O *（。ramcode）。=对齐（8）；*（.RAM）；
但这给了我一个链接错误生成错误：找不到cyflash啊
如果Ichange to *（Cyflash）
建立在文件的程序仍在。文本。
从.map文件：
。text.cysettempint 0x00005188 0x90。    i2ccompliancechecker CortexM3 arm_gcc_473调试，（cyflash。O）。text.cysettemp 0x00005218 0x24。    i2ccompliancechecker CortexM3 arm_gcc_473调试，（cyflash。O）0x00005218 cysettemp



     以下为原文
  The GCC linker documentation is at: http://ftp.gnu.org/old-gnu/Manuals/ld-2.9.1/html_node/ld_21.html
    but when I just put in:
    .data : ALIGN(8)
  {
    __cy_region_start_data = .;

    KEEP(*(.jcr))
    *(.got.plt) *(.got)
    *(.shdata)
    *(.data .data.* .gnu.linkonce.d.*)
    CyFlash.o
    *(.ramcode)
    . = ALIGN (8);
    *(.ram)
    _edata = .;
  } >ram AT>rom
    But this gives me a linker error - Build error: cannot find CyFlash.o
    If I change it to *(CyFlash.o)
    then it builds but the routines in the file are still in .text.
    From the .map file:
    .text.CySetTempInt
                0x00005188       0x90 .CortexM3ARM_GCC_473DebugI2CComplianceChecker.a(CyFlash.o)
 .text.CySetTemp
                0x00005218       0x24 .CortexM3ARM_GCC_473DebugI2CComplianceChecker.a(CyFlash.o)
                0x00005218                CySetTemp

你好，
1。通过修改LD文件，不可能直接将“CyFlash。O”或PSoC Creator生成的任何“.c”文件的对象文件包含在一节中。这背后的原因是因为默认情况下，属于对象文件的函数将包含在Flash中，因此将其添加到SRAM中会引发错误，称存在多个定义。通常可以使用TopeDyfile文件语法（HTTPS://SooStury.Org/BiTurss/DOCS-2.24/LD/Endo-Studi-Basix.HTML）排除通配符中的输入文件。但是，CyFlash .O存储在项目的.file中，因此不能单独从Flash部分排除。因此，将自定义函数中所有“函数”放在“.o”文件中的唯一方法是在“.h”文件（CyFlash .h）中的每个函数声明中都包含“y-AtItTeTyx”语法。
2。如果您自己定义了一些源文件和头文件，并且如果您想将对应于头文件的“.o”文件放置在SRAM /自定义节中，则需要遵循以下步骤：（i）在.DATA节中，用.text节引用添加完整路径和文件名例如，.CORTEXM3ARMGCGC.43Debug MyFrase.O（.Text .Text）*，其中包括MyFrase.O在SRAM中。（ii）我需要从Flash中排除这个“.o”文件，这样对于同一个函数没有多个定义。因此，在.text部分中，用“*（.text .*.GNU.LIKON.T.*）”替换“*”（排外文件（.CORTEXM3ARMGGCUC43Debug MyField.O）.text CopyDeFig文件（.CORTEXM3ARMGGCK433Debug MyField.O）.text .*GNU.LIKONT.T.*）。这将从Flash中删除MyFrase.O。

  Hi,
    1. It is not possible to directly include "CyFlash.o" or the object file of any ".c" file generated by PSoC Creator, in a section by modifying the LD file. The reason behind this is because the functions belonging to the object file will be included in Flash by default and hence adding it into SRAM would throw errors saying that there are multiple definitions. It is normally possible to exclude an input file from a wildcard using the EXCLUDE_FILE syntax ( https://sourceware.org/binutils/docs-2.24/ld/Input-Section-Basics.html ). However, CyFlash.o is stored inside the project's .a file, so it cannot be excluded individually from the flash section. So, the only way to place all the functions in that ".o" file in your custom section would be to include "__attribute__" syntax in each and every function declaration in the ".h" file (CyFlash.h).
    2. If you have defined some source and header files on your own and if you would like to place the ".o" file corresponding to a header file in the SRAM/ custom section, you need to follow the following steps: (i) In the .data section, add the full path & file name with the .text section references, for example: .CortexM3ARM_GCC_473Debugmyfile.o(.text .text.*) This includes myfile.o in SRAM. (ii) I need to exclude this ".o" file from Flash so that there are no multiple definitions for the same function. So,in the .text section, replace " *(.text .text.* .gnu.linkonce.t.*)" with "*(EXCLUDE_FILE(.CortexM3ARM_GCC_473Debugmyfile.o) .text EXCLUDE_FILE(.CortexM3ARM_GCC_473Debugmyfile.o) .text.* .gnu.linkonce.t.*)". This removes myfile.o from Flash.

我对这个问题的解决方案是将几个例程需要从cyflash。C和重命名myflash。C与__attribute推到RAM代替闪光。我要复印几CySpc小例程。C以及更换一个简单的for循环memcpy（memcpy也将Flash）。
我想我已经得到所有的代码在内存中，一旦我叫它永远在RAM可以因此改写所有Flash下载图像。总有一个失败的机会，就需要重新编程，通过一个miniprog3但这个机会很小，我可以接受它。
不是简单地把程序从flashto SRAM但是我各种语法错误但有装载机作为优雅（非常小的诊断信息）或重复定义如上所述。

  My solution to this problem is to copy the few routines I needed from CyFlash.c and rename them MyFlash.c with the __attribute to push them into RAM instead of FLASH. I had to copy a couple of small routines from CySpc.c as well and replace memcpy with a simple for-loop (memcpy would also be in FLASH).
    I think I've now got all this code in RAM so once I call it it'll always be in RAM and I can thus rewrite all of FLASH with the downloaded image. There is always a chance of failure which would require reprogramming via a miniprog3 but this chance is low enough that I can accept it.
    Not as elegant as simply pushing the routines from FLASH to SRAM but I tried all sorts of syntax but either got loader errors (with very little diagnostic info) or duplicate definitions as mentioned above.
