In order to work on the XL, your DSi flashcart has to be compatible with the DSi 1.4 firmware.
Your TTDSi will work if you run this update on it:

so i must put these on my card?? thanks for answer :D

Put the files on your TTDS (all of them). Put the TTDSi into a DSi with 1.3 or lower, or a DS Lite (You can't use the DSXL for this).
Then just run the update file like you would a game and follow the onscreen instructions (plug in your DS to AC Power just incase your battery is low).

i dont have a other ds i only the xl :'(

You'll need to find one then, so you can update your flashcart to be DSi 1.4 / DS XL compatible.Borrow one from a friend or family member, classmate, etc.

thanks i gone look for one
