Re: [Efsl-devel] 127 file limit in a subdirectory

SourceForge Headquarters 1320 Columbia Street Suite 310 San Diego, CA 92101 +1 (858) 422-6466

Here is a bit more of information. I have tried two 256M SD cards, both 
with the same result.
efs.myFs.volumeId.SectorsPerCluster=8

Here is a quick snippet of code:

 for(i=0;i<200;i++) {
        get_filename(&state,1);
        strcpy(&tmpstr,state.file_data);
        strcpy(state.file_data,"DATA/");
        strcat(state.file_data,tmpstr);
        file_fopen(&file_gpx,&efs.myFs,state.file_data,'w');
        file_write(&file_gpx,1,"2");
        delay_ms(10);
        file_fclose(&file_gpx);
        }
  fs_umount(&efs.myFs);

The get_filename function just formats and creates my files (currently 
an index of 1up numbers).
I append the directory info to it, then write 1 character, close the 
file, and loop.
I am including a link of a screenshot of that directory (so you can see 
the corruption).
http://www.marslabs.com/dir1.jpg
http://www.marslabs.com/dir2.jpg

Now, if I execute the same code on the root directory, I can write out 
the 200 files without a problem.

Any ideas off hand? Thanks
