Some library function (either in the SDK, libc or whatever you're using additionally) will call memcpy. Even the compiler can generate calls to memcpy.

So you will have to find out which code is calling memcpy here and working from there.

Well it certainly is not a newbie question!

The advanced section is people who develop esp8266 system stuff themselves (i.e. compiler, libraries, SDK, LWIP...)
