I have board from sigmaelevator company (DCD-230) IT USE DSP56F803 for door motor control and we can edit some parameters like(open and clos sped and output Hz etc.) when we configure parameters its working good but when turn power off then on many timesthe parameters configuration is automatic changing
Without we plug the service tool (programing)
If you can give me help how I can solve this problem please
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.
