did someone else have a faint thought that: - the above syntax might be a bit too complicated or non intuitive? - specifying NOR flash might not be appropriate for defining the internal flash for all Cortex-M MCUs? I know that this is mainly a linux shop, using large application processors, but perhaps we can find a simpler way to accommodate the slightly different MCU world. regards, Liviu
