converting a hex file to binary

linx win · 07-19-2006, 02:09 PM

I need to convert a hex file named: WBoot.hex (firmware file) to binary. The following post:
http://sourceforge.net/mailarchive/f...forum_id=43894
suggested the following script:

PHP Code:



int main(int argc, char ** argv) 
      { 
           unsigned int bp[] = { 
          #include "WBoot.hex" 
     }; 
     write(1, bp, sizeof(bp)); 
      }

I copied it to a new file, made it executable and run it but I got the following:

./convert: line 1: syntax error near unexpected token `('
./convert: line 1: `int main(int argc, char ** argv)'

I tried:
$ xxd -r WBoot.hex cxacru-bp.bin
but I got very small file which did not work.

Any idea?

thats not a script, that is c code.. it will have to be compiled, and it does not look complete. is there any #include at the top of the file? i think write is in <unistd.h>

xhi is right; you need to #include <unistd.h> and maybe some other files (check `man 2 write`) at the top of the file first. Then you have to compile it with gcc (in other words `gcc name-of-file.c`) and run the resulting a.out to get your binary file; redirect the output (using the > operator in your shell) to cxacru-bp.bin

Thanks. I got my modem to work finally. Here is the final file code after including your comments:

Quote:

#include <unistd.h>
int main(int argc, char ** argv)
{
unsigned int bp[] = {
#include "WBoot.hex"
};
write(1, bp, sizeof(bp));
}
