PROCESSOR-SDK-OMAPL138: CODE/DATA to L3

Risto Hedman

Part Number: PROCESSOR-SDK-OMAPL138
Other Parts Discussed in Thread: SYSBIOS

Hi,

We're allocating memory for critical data (DSP&SYSBIOS) from non-cached L3 with #pragmas -OK. We would also put some critical code there, it is straightforward with C but haven't found a way to put C++objects there - therefore I would like to ask:

How to forward C++ objects to L3?
How to forward all DSP code/data there?

I would appreciate if some expert could guide us,

Hello,

You can place code/data in different sections using a linker command file, or Program.sectMap() commands in your *.cfg file. Please see the following.

Placing SYS/BIOS code in different memory segments

Regarding your question on C++ objects, please see the response from George Mock in the following E2E thread.

C++ Object Placement in Memory

Hope this helps.
