    Hello Xiangguang,

    For LC4357 device, please use the diagnostic library for SRAM PBIST. The API is SL_Selftest_PBIST(..).

    The example ccs project is located C:\ti\Hercules\SafeTI Diagnostic Library\2.4.0\build\TMS570LC4357_NoOS

    Hi QJ,

    Thanks for your prompt reply.   So here comes my follow up question:  Where to get information of all these libraries and API's?   Is there a document of all the available libraries and API's?

    Another question is:  Is it possible to turn off ECC for these tests?

    Thanks again.

    Hello,

    L2RAM ECC is enabled by setting ECC_DETECT_EN filed in RAMCTRL. The Flash ECC (for TMS570LC4357) is enabled by default, and can not be disabled. 

    Please find the SDL(safety diagnostic library) user guide in SDL installation folder:
