FATFs f_opendir is not showing ??

Everyone,

I tried to count all the directories on the root but only got 2 directories,

What do I missed here ?

I started with :

f_opendir(&dir, ''),

It returns only 2 directories, suppose to be more than 2,

Anyone has the same experience ?

Thanks

Show the whole code loop where you iterate through the file attributes returned.

It can change directory but can not read file properly yet ??

====

for(;;) //first for begin

{

if (Cdir >= ndirs) Cdir = 0;

if (Cdir <= ndirs) {Cdir++;Ctrk=1;};

ntrks = get_tracks(AlbumTbl[Cdir], 1); /* Get tracks of

current album */

printf('Curent directory : %d \n',Cdir);

if (strk == 2) {

Ctrk = ntrks - 1;

} else if (strk == 1 || Ctrk >= ntrks) {

Ctrk = 0;

}

strk = 1;

for (;;)

{ //loop the directory until ends, second for begins

strcpy(fname, AlbumTbl[Cdir]); /* Play a track */

strcat(fname, '/');

strcat(fname, TrackTbl[Ctrk]);

printf(fname);printf('\n \n');

//check if directory finish begin

if (++Ctrk >= ntrks )

{

printf('Track finished.. \n');

//Cdir++;//next directory

break;

}//end if

//check if directory finish end

HAL_Delay(250);

}//second for ends

} //first for ends

with this code, it's only entering the first directory, it can see the

next directory but never enter it...I have no idea yet where do I miss ?

I can show you the function if you don't mind..

====

ndirs = get_albums(); /* Get albums and generate card status ID */

for(;;) //first for begin

{

if (Cdir >= ndirs) Cdir = 0;

ntrks = get_tracks(AlbumTbl[Cdir], 1); /* Get

tracks of current album */

printf('Curent directory : %d \n',Cdir);

for (;;)

{ //loop the directory until ends, second for begins

strcpy(fname, AlbumTbl[Cdir]); /* Play a

track */

strcat(fname, '/');

strcat(fname, TrackTbl[Ctrk]);

printf(fname);printf('\n \n');

//check if directory finish begin

if (++Ctrk >= ntrks )

{

printf('Track finished.. \n');

if (Cdir <= ndirs) Cdir++;

break;

}//end if

//check if directory finish end

HAL_Delay(250);

}//second for ends

} //first for ends

Neither of these two posts show you calling FatFs API functions, or indications from you where this deviates from the content you expect on the media.

Useful information would help you debug

  printf('Curent directory : %d \n',Cdir); // Also print out ntrks so you understand what is expected to be enumerated

I have 8 directories and I want to display the content of the

directories, first directory ==> list the track until finish, going to

the second directory ==> list directory...until the 8th directory,

return to the first,

I've made :

printf('Total track : %d \n',ntrks);

from your inspiration, so far it can display only two of the first

directory, but from directory 0 jump to directory 2, I have no idea yet

why ?

Looks like the track is not reset to 1 everytime it's changing

directory, that's probably my puzzle ?

without loop in Cdir, I put Cdir with value, it's working, but it can

not jump to another directory :

Code :

Cdir = 0;

ndirs = get_albums();

printf('Total directory : %d \n',ndirs);

printf('Curent directory : %d \n',Cdir);

ntrks = get_tracks(AlbumTbl[Cdir], 1); /* Get

printf('Total track : %d \n',ntrks);

for (;;)

{ //loop the directory until ends, second for begins

//Ctrk++;

strcpy(filename, AlbumTbl[Cdir]); /* Play a

strcat(filename, '/');
