I want to work on mini2440 with out OS. I am using Keil 4 as a compiler. But It is required to down load .bin to the board & keil 4 is giving .hex file. I also tried (simple led flashing program) to generate .bin file from .axf file & also from .hex file. But that didn't work. Can anybody suggest me the proper solution? ThanX, Dusane
