sw memory size

[hjjeon]

I 'm developing using a nrf51822 and use 256kb rom 16kb ram. I met ram overflow frequently. so,I want to calculate the ram size at the map file. could you explain how to calculate the ram size at the map file? BR

You don't have to look at the map file to determine RAM usage, it's sufficient to look at the sizes output by Keil at the end of compilation. You can find total RAM usage by adding ZI-data to RW-data. For further details, take a look on this Stack Overflow question.

For tips on how to reduce RAM usage, take a look at this.

thank you for your consideration

No problem, but if you found my answer useful, you'd help everyone by accepting it, instead of posting a thank-you-answer. :-)
