XIAO report Used RAM?

XIAO compiler report used flash.
Is there a way for me to know how much RAM reserved?

That’s a good question. Is there a device that you can see that retains RAM reserved? Maybe I can refer to it and add it to the XIAO. @shoo

Look at this picture, there is no RAM retainsed. @shoo

Sorry, there is not an answer to the initial question! All Atmel based boards and the ESP8266 / ESP32 families shows the used / free flash and ram. The SAM21 family shows only flash.
Shoo (and me) is looking for a way to add this feature to the SAMD faily.
