Hi all,

Im in the final stages of a project and have hit a big glitch need your help! please

I have the arm evaluator 7t connected to a pc running metrowerks codewarrior.
I am trying to open a text file hosted on the pc hard drive

When i try and run my code in the emulator mode (armul) the code works fine the file is found and ll is well. However when i run the same code on the arm board it runs and says it cant find the file. The code in question is:-

CODE:

FILE *file_ptr;

        int address[2014], value[2014], i, j;

        file_ptr = fopen("M:\\Documents\\final project local\\book1.txt","rt");

        if (file_ptr !=NULL)

                {

                        printf("settings file found\n");

                        for (i = 0; i < 2014; i++)

                                {

                                        fscanf(file_ptr,"%x",&address[i]);

                                }

                        fclose(file_ptr);

                }

                else

                printf("file not found\n");

}

any ideas??? thanks

well the function calling seems ok..
some more details wud have been better... cud u give a little more insight of the system?
which uart are u using hope u r using uart1 instead of uart0... u will nwwd the right handshaking to read the file properly also
M:\\Documents\\final project local\\book1.txt is a long enough address try
something shorter and without spaces in between

ex k:\\project\\test.txt
