AWR1642BOOST: Compiling Warming for the mmWave SDK 1.1.0.2 #10370-D DSP

Part Number: AWR1642BOOST
Other Parts Discussed in Thread: MMWAVE-SDK

Hello 

When I complied the mmWave demo in the mmWave SDK 1.1.0.2, there is a compiling warning:

#10370-D Possible codesize or performance degradation. Section ".text:SOC_init:libsoc_xwr16xx.ae674<soc.oe674>" has calls to rts routines, but rts is placed out of range from call site at 0x200030e0, or in a different section. To optimize codesize, either 1) place rts closer to call site, or 2) place rts in same section, or 3) compile with --disable_push_pop. 

I believe that I had enabled the diable_push_pop. So how can I solve this warning?

Regards

Peter

    Hello Peter,
    Have you modified anything in the SDK ?
    Have you installed the right dependency tools when installing the new version MMWAVE-SDK ?

    Hi Raghu

    I did not modify the code. I did not use the dependency tools comes with the MMWAVE-SDK. I downloaded those tools from TI website and installed them separately. The attached picture shows my environment. And the console output is attached too.

    Hello Peter,

    We are aware of this and have deliberately let it remain so. Yes, it is annoying but overcoming it may not be the right thing to do. Firstly, for the understanding of what it really means, take a look at my e2e question a few years back and compiler expert response below:

    https://e2e.ti.com/support/development_tools/compiler/f/343/t/431202

    In AWR parts the code size is under pressure so the push-pop default optimization is a good one. The problem happens because we overlay some code with L1PSRAM (to reduce code size as is explained in user guide) so the caller (which may be in L2SRAM) and callee (in L1PSRAM) are too distant and cause trampolines to be generated which can wipe out the default compiler push-pop optimization code (that requires near calls hence requires trampolines to overcome) savings. The push pop savings is more fundamental in nature than the side effect due to trampoline generation and push-pop savings affects all code, not just that which is in L1PSRAM (that is callee-caller within L2SRAM also which will be near). So in my view, it is not advisable to overcome this warning by disabling push pop, and this decision will have to keep being re-evaluated every time we do maintenance changes so it is best to let the warning remain exposed so the user can make their own judgment about it.
