如何使用Keil中的fromelf工具为PSoC6生成bin文件？

我找到了解决这个问题的快速方法。
实际上，输出是基于FROMLF用户指南信息的。
使用时应注意的问题
如果将包含多个加载区域的ELF图像转换为二进制格式，则FulMelf创建一个
输出目录名为目的地，并为每个加载区域生成一个二进制输出文件
输入图像。FROMLF将输出文件放置在目标目录中。
生成的文件与链接器文件加载区域对齐。例如，对于CM4内核，MCU内部闪存的区域如下。
LRSflash闪光灯启动闪光灯大小{ErFlash矢量+ 0 {*（重置，+1）}
ErFlash代码+ 0固定{*（根目录$$部分）*（+RO）}
ErthRaMa向量RAMYSTART UNIIT {*（ReSETYRAM，+1）}
ErthRaMyDATA + 0 {*（CyrRAMFUNC）。任何（+RW，+ZI）}
将变量放置在设备启动期间不应初始化的节中。ErthRaMiNoiTixDATA + 0 UNIIT {*（.NOIIT）}
用于安全应用程序和Bootloader SDK应用的数字签名。截面的大小取决于所需的数据大小。CythAppII签名（Flash启动+ Flash大小-256）256 {*（.CyAppApple签名）}
因此，CM4.Bin文件夹中的输出文件中有四个区域。我只需要把它们串联起来。Linux命令可以帮助实现这一简单。
$猫Era Flllh矢量ErlFlasyEnter ErlRAMYA数据Erm RAMY-NOYNONITIT & G.CM4.Bin
那么MeGe3文件意味着什么呢？如果使用FROMEF工具为CM0内核生成bin，它们实际上是相同的四个负载区域的CM0 bin文件。您可以轻松地根据文件大小检查哪一个文件与CM0文件中的哪些区域有关。这是因为CM4 AXF文件实际上合并CM0和CM4图像。

  I have found a quick solution to this problem.
 
Actually what is output is expected based on fromelf user guide information.
 
Considerations when using --bin
If you convert an ELF image containing multiple load regions to a binary format, fromelf creates an
output directory named destination and generates one binary output file for each load region in the
input image. fromelf places the output files in the destination directory.
 
The generated files aligns with the linker file load regions. For example, for cm4 core, the regions in MCU internal flash is as follows.
 
LR_FLASH FLASH_START FLASH_SIZE
{
    ER_FLASH_VECTORS +0
    {
        * (RESET, +FIRST)
    }
    ER_FLASH_CODE +0 FIXED
    {
        * (InRoot$$Sections)
        * (+RO)
    }
    ER_RAM_VECTORS RAM_START UNINIT
    {
        * (RESET_RAM, +FIRST)
    }
    ER_RAM_DATA +0
    {
        * (.cy_ramfunc)
        .ANY (+RW, +ZI)
    }
    ; Place variables in the section that should not be initialized during the
    ; device startup.
    ER_RAM_NOINIT_DATA +0 UNINIT
    {
        * (.noinit)
    }
    ; Used for the digital signature of the secure application and the
    ; Bootloader SDK appication. The size of the section depends on the required
    ; data size.
    .cy_app_signature (FLASH_START + FLASH_SIZE - 256) 256
    {
        * (.cy_app_signature)
    }
}
 
So what appears in the output file in cm4.bin folder has four of the regions. I just need to concatenate them together. Linux command can help achieve this easliy.
 
$cat ER_FLASH_VECTORS ER_FLASH_CODE ER_RAM_DATA ER_RAM_NO_NOINIT > cm4.bin
 
Then what does those .merge0 to .merge3 files mean? They are actually the same files for cm0 bin for the same four load regions if you use fromelf tool to generate bin for cm0 core. You can easily check which file relates to which regions in cm0 file based on file size. This is because cm4 axf file actually merges cm0 and cm4 image.
