How can I read/save of internal flash of DSP56F803?

[trytohelp · Accepted solution]

Hi Oleg,

With CW for DSP v8.3 and previous version Processor Expert (PEx) feature was included.

PEx includes a bean to manage the Flash memory in your application.

This bean is named IntFLASH.

You will find more details at installation folder:

    \CodeWarrior for DSC56800E v8.3\ProcessorExpert\BEANs\IntFLASH

You can create an example using the bean too with the project wizard:

    File + New .. + Processor Expert Examples Stationery + DemoApplications + HWBeans + 56F80x + InFlash

The Example is for DSP56F807 but you can move to 803.

To do that you just need to add a the DSP56F803 device and select it.

The Generated code will be done for DSP56f803.

Have a great day,
Pascal

Thank you for the answer.

But how to ERASE and WRITE  flash of  DSP56F803?

I can't do it by "load memory" menu.

Could you explain more detail how to write .hex or .s file to flash by CW and USBTAP?

Thank you in advance.

Hello Oleg

CodeWarrior v8.3 can only load ELF file into DSP56F803. It does not support writing the flash with .hex or S record file.

The command 'Load Memory' and 'Fill Memory' in debugger can only be operated in RAM, not in flash.
