Many of Cortex-M processors support the use of external RAM and flash, being generally capable of running Linux. Typically, the developer faces the task of adding support for new I/O interfaces and corresponding software stacks such as WiFi, SD Card with FAT32, diverse USB connectivity in host and/or device, fancy user interface with a touch screen, etc. Linux is being looking attractive as an essential choice, supporting much all functional features one may desire in recent embedded applications.

However, optimizing and customing Linux to fit Cortex-M series comes with large engineering efforts, and in this session, we would like to share the experience about eliminating the general application and kernel footprint by means of modern techniques like Thumb2 tweaks, link time optimization, and automatic feedback directed optimizer.
