Hi, Kordo

As you know that the DSP56F803 has on-chip program flash, data flash and SRAM, for your issue that the modified parameters are not updated after power off/on, it is obvious that the parameters are not saved in on-chip flash in time.

The DSP56F803 is about 20 years, it is end of life.  we provide the flash erasing/programming function in PE in CodeWarrior for DSP56F803.


Because your board is third party product, pls report the issue to board manufacturer.

Anyway, the PE provide the function to erase/program flash in CodeWarrior for DSP56800E tools, pls refer to it and write the code yourself.

Hope it can help you
