Compiler: Different processing results between F28335 Simulator and on F28335 target

Tool/software: TI C/C++ Compiler

Hi,

I know that simulator of F28335 is not officially supported but I am asking the question if someone had the same issue that I am facing but that found the solution.

I am using "simulator" of the F28335 to check first some processing without the need to be connected to a F28335 target.

I am also using the fast library: rts2800_fpu32_fast_supplement.lib.

Thanks to previous TI forum support, I am now able to run this fast library with the emulator (loading the ROM memory when using the simulator).

So now I was expecting to find exactly the same results on the target and with the simulator.

However now when I compare the results between Simulator and Real target I do not have the same results (some digit after the comma).

I checked the .map for two tests (Emulator, simulator) and it is the same. So I guess I have the same code.

Did you have already this issue?

Is it normal to have some differences in the processing results ?

Thanks for your support

Mathieu
