kea64 storing default settings in flash

[krzysztofszot]

Hello, 

I am trying to store default user settings in flash during programming so that when the device first boots up there are default values my user settings section of flash instead of it being filled with all FF's.  I am sure there is some thing simple i need to do in the code to assign these values during the build.  I can read and write the values after the initial flash but every time i make some code changes and flash the unit with new firmware these are the default 0xFFFFFFFF and i have to enter these again.  

   There has to be a #pragma or or declade as const something similar that I need to do in code but I am not sure what i need to do in the code, any help would be greatly appreciated.

Hi Krzysztof

See the links below for binary references showing the KEA64 using a parameter system that takes default values at startup and can the be modified as desired.

File and parameter system: http://www.utasker.com/docs/uTasker/uTaskerFileSystem_3.PDF

Beware that when you load new code with debuggers they may delete also parameter storage areas even when not programming code there (check the debugger setting to see whether you can get it to delete only the area needing deletion for the code). If there are still issues you can install a boot loader for loading code with that preserves parameter areas.
