ARM 7 TDMI

Hello I am  new to this forum and new to Arm 7 programming.

My question is - I have a programming (I think it is a Flash) file in hex ,which I downloaded to Arm 7 MCU through Rlink usb tool to run the programme.

If I need to modify this programme how do I do this?

Thanks

Parents
  • If the dis-assembly code can be generated, is it match your intention? If it is enough, I will provide the following code.

    #include <stdio.h>
    FILE *fp;
    main(int argc, char *argv[])
    {
    int ch;
    int pos=0;
    fp = fopen(argv[1], "rb");
    printf(".text\n");
    printf("main:\n");
    while((ch=fgetc(fp))!=EOF){
      if(pos==0){
      printf(".byte\t");
      }
      printf("0x%02x",ch&0xff);
      if(pos==7){
      pos=0;
      printf("\n");
      }
      else{
      printf(",");
      pos++;
      }
    }
    fclose(fp);
    }
    
    

    This is to convert a binary code to an assembler source.

    By using the objcopy command, you can get binary file corresponding to the hex file.

    You can assemble the source file and get dis-assembly code by using the objdump command.

    The following is an example.

    $ cat tmp.hex

  • If the dis-assembly code can be generated, is it match your intention? If it is enough, I will provide the following code.

    #include <stdio.h>
    FILE *fp;
    main(int argc, char *argv[])
    {
    int ch;
    int pos=0;
    fp = fopen(argv[1], "rb");
    printf(".text\n");
    printf("main:\n");
    while((ch=fgetc(fp))!=EOF){
      if(pos==0){
      printf(".byte\t");
      }
      printf("0x%02x",ch&0xff);
      if(pos==7){
      pos=0;
      printf("\n");
      }
      else{
      printf(",");
      pos++;
      }
    }
    fclose(fp);
    }
    
    

    This is to convert a binary code to an assembler source.

    By using the objcopy command, you can get binary file corresponding to the hex file.

    You can assemble the source file and get dis-assembly code by using the objdump command.

    The following is an example.

    $ cat tmp.hex
