Code suggestion about copying some data into flash memory in runtime

Habib Ali Subhan

Dear All,

I am working on F28335 controller and using C2000 simulator and code composer studio v3.3. I am running a program from flash which takes a adc data and makes some decision upon it. What I want to do is to write the data in to flash memory of my controller while making sure that no part of the code which is already present in the flash do not get interfered or replaced by the data. Please help!! I cant use eeprom. Is there any solution to save the code in some particular sections of flash and the adc data in other section so that both will not be mixed......please suggest some code to do it that way

Regards

Hi,

There is an application note called "EEPROM Emulation With the TMS320F28xxx DSCs" with associated files, which perhaps can help you. The link is the following:

One note is the simulator will not allow you to use the flash API to write to the flash (the hardware resources to do so are not in the simulator. But for a real device, what Denise suggests will work.

Hello TI,

did you find a way to do this, since i'm trying to do the same?

what i have done is trying to change the Flash280x_API_Config.h and Library.h to match the F28035, but the lib includes i cannont change how did you manage to do this,

what did you change, and how did you include this in your existing project.

best regards
