I have inherited a project for an arm 7 (Atmel AT91SAM7S256) with an IAR workbench IDE. I have noticed that I can flash this micro through the J-Link probe, with motorola type files (.mot). I assume this is some sort of s-record format. I imagine it uses s-record because it has a risk architecture. There is also another DFU startup code that allows for USB flashing with what I believe is a raw-binary format. My question is how can this micro be flashed with two different types of binary images?
