In Cooper v. State, 45 S.W.3d 77 (Tex. Crim. App. 2001), the court noted that although appellant's amended notice of appeal stated the "substance of this appeal was raised by written motion and ruled on prior to trial," the appellant's issues did not have anything to do with pretrial motions. Instead, they challenged the voluntariness of his guilty plea. Cooper, 45 S.W.3d at 78. The Cooper court concluded Texas Rules of Appellate Procedure rule 25.2 "does not permit the voluntariness of a plea to be raised on appeal" and affirmed the appellate court's dismissal of the appeal for want of jurisdiction. Cooper, 45 S.W.3d at 83.
