RTOS/TDA2PXEVM: SBL(MLO) build Image size difference

Part Number: TDA2PXEVM

Tool/software: TI-RTOS

Hi,

We are working on Tda2px EVM Hw and using VSDK3.03 for source & build . As per TDA sbl user guide , When I tried to build SBL using “make -s sbl”, it generates the MLO 107kb (110516 bytes).

If I go for  SBL image build using below mentioned command order as per VisionSDK 3.03 user guide instruction, 

gmake -s –j4 depend

gmake -s –j4

make -s sbl –j4

 

then , It generates the MLO 107kb (110560 bytes). Here , I observed 40 bytes different in both generated MLOs.

 

Is there any SBL build dependency on specific library or flag variables?

 

As per my understanding SBL(MLO) can build independently .I also find that, tda2px evm board boots up successfully with both generated SBL(MLO) image ,

But, I observed that particular ADAS use case  scenario successfully works, when I use SBL, which is built without depend flag(gmake -s –j4 depend ).

Please let me know you inputs ,so i can root cause the issue.

Regards

Raj

    Hi Raj,

    SBL configuration can be different depending upon the build flags.
    Please see SBL configuration in PROCESSOR_SDK_VISION_03_06_00_00\ti_components\drivers\pdk_01_10_02_07\packages\ti\boot\sbl_auto\sbl_lib\src\tda2xx\sbl_lib_config_tda2xx.h.

    What is the ADAS use case that is failing and can you describe the steps in detail in passing as well as failing case.
