TMS320F280039C:How to write data to a fixed address in memory

K.Z

Other Parts Discussed in Thread: C2000WARE

Hi All,

We would like to write production data and adjustable parameters in the production process at a fixed address in memory.
How should we program to do this?
Do you have any sample sources or reference documents?

Best Regards,
Ito

I assume you want to write it at flash location (non-volatile) memory. You should be able to do it using the flash API. You can refer "flashapi_ex1_programming" example in driverlib\f28003x\examples\flash folder of C2000Ware.

Hi Singh,

I understand that I have to use FlashAPI.
Next, please tell me the specific programming method.
To write data to an arbitrary Flash address, do I need to rewrite the .cmd file?
If so, please let me know how to rewrite it.

Best Regards,

Hi Singh,

Is it possible to write to a specified address even in a way like the one shown in the image?

Yes, you can use #Pragma to allocate any variable/structure at fixed location.
