Arduino: How to get function "FreeRAM()" to work?

Created on 11 Dec 2015 · 2Comments · Source: esp8266/Arduino

Hello,
I have seen in libraries/SD/src/utility/SdFatUtil.h
a function FreeRAM(), but it does not compile, with error:
undefined reference to__brkval'`

What can I do to make FreeRAM() work?

Regards, Rudolf

Hello Markus,
Thank you very much again for your help.
I have searched for memory and RAM only, so I could not find getFreeHeap.
Regards, Rudolf
