Second day of trying to get my head around the blitter on my Jag. Not going as well as I hoped and much head scratching was being had. Thankfully chatting on IRC with some helpful fellow Jag coders got me sorted. Some handy snippets of blitter set-up code, commedy drivel and me finally spotting a rogue BSS section in one of my source files soon had me right.
Apparently the use of and users of the blitter are “Evil” and the cause for much suffering according to some 🙂
So far I am just using it to clear a chunk of RAM, tomorrow post work should see more progress in the blitter side of the force. Hopefully then I can start bringing all these bits and pieces together and make something prettyish to look at 🙂
