Generating a texture and using as Source Image

I've written a method to generate a texture for my minimap. All non-obstacle tiles are blue, and the obstacles are white. This is very easy, and I've saved the texture to a file to make sure this part is working.

However, when I want to add this as a source image in my gui image, all I get is a grey square. See code below.

 Texture2D minimapBackdrop;
 public void Init( bool[,] obstacleMap ){

     this.obstacleMap = obstacleMap;
     minimapBackdrop = GenerateMinimapTexture ( obstacleMap );
     Rect rect = new Rect (-40f, -240f, minimapBackdrop.width, minimapBackdrop.height);

     Sprite s = Sprite.Create (minimapBackdrop, rect, Vector2.zero );
     s.name = "Minimap Sprite";
     Image im = gameObject.GetComponent<Image> ();

     im.sprite = s;
     im.overrideSprite = s;
     initialised = true;

 }

Based on my googling on the topic, I have to create a sprite and assign this to the Image element, which is what I'm trying to do here.

It works if I save the texture as a .png and, via the editor, drop it on the image, so maybe the issue is with the created sprite, but I can't find what it is.. The name of the Source Image changes to "Minimap Sprite".

I found this question where someone seems to have the same problem, but it's not answerred. http://answers.unity3d.com/questions/942758/problems-with-spritecreate-in-current-version.html

Thanks!
