This document describes the Serial Asynchronous Port based Flash Programming Utility for the TMS320LF240x DSP Controllers. This utility leverages the Boot ROM on these DSP controllers to provide a stand alone flash programming capability independent on the previous contents of the flash. The serial port flash programming utility can be applied to in-system programming for the DSP controller. The Serial Flash Programming Utilities share the core flash programming algorithms with the JTAG Based Flash Programming Utilities. Another major difference from the F24x Serial Programming is that the RAM resident kernel is not fixed, copied from flash. It is downloaded run-time, resulting in added flexibility.……
