Hi Nabendu,
Hi,
concerning the footprint I'll give you the relevant part of the output of the compilation process for the ipc_pingpong example:
text data bss dec hex filename 9122 640 880 10642 2992 /home/n8fear/src/RIOT/examples/ipc_pingpong/bin/arduino- mega2560/ipc_pingpong.elf
I hope this helps.
