How to start working with fromelf?

OK, thank you for replay, but in that tutorial I can not understand - links between compiller and fromelf. My target is .bin format from Keil IDE, for boorloader.

You use fromelf on the Linker output.

See the uVision documentation for setting output format via the IDE...
