All we need to provide to C at this point is a region in memory dedicated to its stack. This is done by allocating a region in .bss and pushing its start address to esp. Since the multiboot spec says it is not safe to rely on the initial stack provided by the bootloader, this patch provides our own stack. Galileo boards have 512Kb of SRAM and 256Mb of DDR3 RAM, so providing 8kb as a start seems safe. Moreover, stack sizes are very application-oriented so it may be too early to provide a bigger (or smaller) stack.
The Contiki Operating System
Contiki is an open source operating system that runs on tiny low-power microcontrollers and makes it possible to develop applications that make efficient use of the hardware while providing standardized low-power wireless communication for a range of hardware platforms.
Contiki is used in numerous commercial and non-commercial systems, such as city sound monitoring, street lights, networked electrical power meters, industrial monitoring, radiation monitoring, construction site monitoring, alarm systems, remote house monitoring, and so on.
