The Keil development environment supports the function of confirming the RAM and ROM size used by program during compilation. If the RAM and ROM used by the program exceed the chip size, Keil will automatically display warning message.

NUC240VE3AN is used as example below to illustrate how to check RAM and ROM:

Invoke Target Options.
In the Linker tab, enable “Use Memory Layout from Target Dialog”, and remove --first='startup_NUC230_240.o(RESET)' in the Misc Controls field.
In the Device tab, select NuMicro Cortex-M Database under the Database pull-down menu, and then select a specific part number.
In the Target tab, enable IROM and IRAM1 as default, and then select Startup as IROM1.

After completing the steps above, when the RAM and ROM used by the program exceed the supported chip size, Keil will automatically display warning message.
