Memory map prevented reading 0x007ED85C

Maha Ahmed

Dears,

I'm working on the TMS320C6670 Evaluation Module DSP and code composer (CCS5.5).

I'm having a problem during opening file.

For simple example:

FILE *fp2;

fp2 = fopen("Book1.csv" , "r");

And the Book1.csv has 4000 elements.

While I was using the CTRL+R to run this line:

fp2 = fopen("Book1.csv" , "r");

I got this error:

Error: Memory map prevented reading 0x007ED85C

So, how can I solve this problem ?

Please follow the following code snippet for file open.

File Read:

FILE *fp2 = 0;
fp2 = fopen("Book1.csv" , "rb");

Please refer Image Processing example source available in MCSDK.(mcip_master_main.c). I hope this helps.

If the full path is not specified, the (Book1.csv) file will be created under project debug directory.

Please download the latest MCSDK 02_01_02_06 from below link.

Thanks.

Hi Rajasekaran,

Thanks for your reply.

I modified the code using those two lines which you are mentioned but still the problem exists.

I'm downloading now the latest MCSDK 02_01_02_06 then I'll check again.

Thank you very much.

Hi Maha,

The error message seems to be related to project configuration. Please work with MCSDK examples and try to modify it for your purpose.

Please try the example program posted on below post.

Thanks.
