TMS320F28377D: Execute code from an arbitrary memory location.

Samuel Ors

Part Number: TMS320F28377D

Hello.

We are exploring the possibility of load a binary chunk of code (generated by a customer) into RAM and execute it from there.

I have tried by using the --relocatable option in the project we are loading into RAM,but it seems all the function calls and global memory access are absolute, so it doesn't work.

Is there something I am missing ?

Thank you.

Samuel.

My apologies for the delayed response as i was out of office. I will bring this thread to the attention of the compiler experts.

If you are trying to somehow implement position independent code ... The C2000 compiler tools don't support that.

The --relocatable option is for partial linking. That is when you link together some object files that are only part of the final application. At some later point, this partially-linked file is yet another input to the link that creates final application executable. This final executable is always absolute.

Thanks and regards,

-George
