This application note describes how to manage the booting of multiple executables from external memory at run-time, thus providing the flexibility to dynamically switch among them. This project was implemented on the ADSP- BF561 EZ-KIT Lite® evaluation system (ADDS-BF561-EZLITE, Rev 1.1) and applies to the ADSP-BF561 Blackfin® processors with silicon revision 0.2 and beyond.
