SD "dir"-command

i trying convert output "serial" "tft" using 2.8" inch tft lcd display touch screen module micro sd solt arduino uno.

i use sd card test library starting point, , working point directory listning starts.

i cal fine initialice, , read data micro sd disk, size, totals , so, when comes this:

 root.openroot(volume);
   
   // list files in card date , size
   root.ls(ls_r | ls_date | ls_size);

... stops working...

program-listning:
/*
   sd card test
   
  example shows how use utility libraries on the'
  sd library based in order info sd card.
  useful testing card when you're not sure whether working or not.
     
  circuit:
   * sd card attached spi bus follows:
  ** mosi - pin 11 on arduino uno/duemilanove/diecimila
  ** miso - pin 12 on arduino uno/duemilanove/diecimila
  ** clk - pin 13 on arduino uno/duemilanove/diecimila
  ** cs - depends on sd card shield or module.
         pin 4 used here consistency other arduino examples
