A defendant may not appeal from a judgment entered upon a plea of guilty. Bridges v. State, 376 So.2d 233 (Fla. 1979); Walker v. State, 399 So.2d 374 (Fla. 3d DCA 1981). This appeal is accordingly dismissed without prejudice, however, to a subsequent consideration of a Fla.R.Crim.P. 3.850 motion based upon alleged ineffective assistance of trial counsel or any other appropriate ground.
