TMS570LC4357: STC1 Test of CPU Cores and the expected value of STCCICR at the end of SRC1 Run completion

Part Number:TMS570LC4357

Hello Support,

For STC1 test of CPU, due to errata, both the cores shall be executed together.

Hence the total interval of test cases is 125+3 = 128 = 0x80.

At the end of STC1 run completion with both cores being tested, what should be the expected contents of STCCICR register?

I am thinking it should be 0x0080_0080.

I am getting instead a value of 0x007D_0080, which indicates CORE2 is not running the uSCU test cases.

Can you please confirm if this is the intended design or I have device failure?

I see no time-out error and I also see TEST_DONE=1

Thank you.

Regards

Pashan
