Hi Mark, >From https://github.com/RIOT-OS/RIOT/wiki/FAQ Q: How much memory (ROM/RAM) will it need? A: When you compile an application for a board, the last thing printed gives each sections memory footprint and looks like this: text data bss dec hex filename 77732 296 24272 102300 18f9c applications/sixlowapp/bin/iot-lab_M3/sixlowapp.elf The required RAM is data + bss, ROM is text + data.
