sorry, I don't understand your question. yes, cortex-m devices have internal flash and ram, and this is not a STM only feature. > ..., rather than setting your props using -global, > the multiple boards will set them.

QEMU is supposed to implement fixed boards using -M. yes, I am aware of this, but in the cortex-m world this simply does not scale, there are too many different variants of the same mcu, and too many boards. it is not realistic to imagine that all the mcu variants will ever be emulated as separate boards. so, for some cases, referring to one existing board/mcu and slightly adjusting the flash/ram sizes might provide a temporary solution. regards, Liviu
