Hi Support,

In my application, I want to load tasks from the shared MSM into L2SRAM while keeping L1P /L1D as cache.

during the linking process task will be linked in shared MSM and will be copied to L2SRAM at runtime to execute.

I am not sure how to configure linker to generate relocatable code? as the code references will change when it will be copied to L2SRAM for execution.

Thanks.

Hi,

Can you elaborate a little? Which sw example are you using ? Which RTOS SDK version?

As a general guideline, have you tried this method:

Hi,

Maybe overlay can be useful: look at SRU186 Linker manual and search for overlay. For instance, look at "7.8.12 Splitting Object Components and Overlay Management".
