The purpose of this study is to prepare the Blackfin STAMP board with a BF537 core to work as a SDR system (Software Defined Radio System) under a GNU-Linux platform. Due to all the documentation and support found in the web and the release under GPL (General Public License), the distribution used to develop SDR is μClinux. This work explains what is needed to build a SDR system in the Blackfin board, the inconveniences found in the actual μClinux distribution and all the workarounds and approaches made to start porting the software needed to the operating system. To make it work, some codes of the linux kernel, such as device drivers, had to be reviewed so they could adjust to the application demands. In short, this work explains what has been modified in the μClinux distribution and why such changes are done to make SDR possible in the Blackfin board
