What does 'address' mean in HWI of ROV?

Yoonsun Kim

Hello,

I am trying to load ISR function to L2SRAM. I assigned ISR function to L2SRAM by CODE_SECTION and checked it is in L2SRAM area in map file.

I loaded and checked again by ROV tool. I saw four HWI function, but the address of my ISR function was not what I expected.

It looks that the meaning of address of basic tab is different from function loading address.

Anyhow I don't know what is the difference in operation when address area is in L2SRAM and when in DDR3.

Can I get more detail explanation and how to move instance address to L2SRAM from DDR3?

Hi,

The address you are seeing is not the address of the Hwi's function; rather it is the address of the Hwi_Handle (which points to the Hwi instance).

Hi Steve,

I want to move Hwi_handle address to L2SRAM from DDR3 like other instances.
How can I change it?

Yoonsun Kim,
each module has a property 'common$' described here: rtsc.eclipse.org/.../Types.html$
You can use its property 'instanceSection' to allocate instances to a preferred section:
Hwi.common$.instanceSection = ".handles";
Then, you have to allocate that section to L2SRAM:
Program.sectMap[".handles"] = new Program.SectionSpec();
Program.sectMap[".handles"].loadSegment = "L2SRAM";
