This program worked fine under 2.4.3 however under 2.4.5 the program runs but nothing appears on the FB. The memory I am writing to does not appear to be the frame buffer. Nothing has changed in my fb driver so I am wondering if anything has changed in how memory is mapped via the kernel? Thanks for your consideration -- Scott A. McConnell
