Hello,

please if anyone test PBIT using SDL (safety diagnostic library) or using Halcogen

please give me steps how to test it OR share with us your test code

i ran SDL with my board and here is the results .are they correct??

but i have no idea how to check PBIT like how to just enable PBIT and disable the other tests??

i successfully run SDL with my board with no fails

but i have no idea how to check PBIT like how to just enable PBIT and disable the other tests??

i followed sl_selftest.c i make sure this code compatible with what PBIT sequence in the TMS570LSxx ( Chapter 7 7.3.1)

and followed C:\ti\Hercules\SafeTI Diagnostic Library\2.4.0\demo_app\HALCoGen\TMS570LS1227_NoOS\source\sys_startup.c

Hello,

Do you mean what is the difference between HALCoGen generated self test functions and SafeTI Library functions?

Hello Miro

i am asking about the difference in the concept of both built in self test either PBIT or LBIT and the safety concept i didn't touch the difference between them

Typically these tests are run on the MCU at power on reset during system startup. If you look at the sys_startup.c file generated by Halcogen for TMS570LS12x, you will see how the SL_SelfTest_PBIST is run using PBIST ROM. you can locate the code in the SDL here:

C:\ti\Hercules\SafeTI Diagnostic Library\2.4.0\demo_app\HALCoGen\TMS570LS1227_NoOS\source\sys_startup.c

Rahul
