Short Description

GSM/2G is the most ubiquitous mobile communication standard worldwide. Millions of people use it every day. An FPGA based testbed with Digital Baseband Processing (DBB) from the RazorEDGE project on an ML605 board [1] and RF processing on the evalEDGE FMC module is available. A separate board with a CPU is required for Layer 2/Layer 3 (L2/L3) firmware (also referred to as baseband firmware). The Baseband Meets CPU project implements the PULP CPU next to DBB on the FPGA board. Eventually, RF, DBB, and CPU will be integrated into an ultra-low power 2G modem SoC. However, there is no complete and open source L2/L3 firmware available for 2G operation.

In this project, the real-time OS FreeRTOS [2] shall be ported onto the PULP CPU. Subsequently, the L2/L3 source code from Open Source GSM Phone Call, which is based on OsmocomBB [3] and a custom driver, shall run on top of FreeRTOS. This base can then be taken to roll-out an open source L2/L3 firmware project with support beyond voice calls. A protocol tester [4] or OpenBTS [5] can be used as test environment.
