Dear Jaehong,
Just a small additional information to previous Thiago response,
The *"Text" + "Data"* sizes together are the *required space in Flash*,
while *"Data" + "Bss"* is the* RAM *requirement.
*Iotivity-Constrained with RIOT OS Supported Boards:*
Tried Iotivity-Constrained with Nucleo-F4XXre,Raspberrypi 3 and Atmel
Samx2XXpro Boards .
