Atmel SAMD21J18A MC register holding flash memory size

Question

So, I am using Atmel SAMD21J18A MC for an IoT Project, to send data to a remote server. Is there a function or a register holding data, using which I can send the used flash memory and leftover flash memory size at run time?

Thanks!

Generating the linker symbol itself should be toolchain specific. If your linker is not locating code at the start of the ROM, you may need a symbol for the start as well. You need to consult your linker documentation and memory map.
