TMS570LS0914: HalCoGen: CPU self-test issue

Other Parts Discussed in Thread: HALCOGEN,

Hi TI Team,

I would like to report a potential issue with HalCoGen generated code for CPU self-test on TMS570LS0914.

When using HalCoGen to generate the CPU self-test code, the test was always failing on my board with failure register = 0x03.

I noticed that the STC interval generated by HalCoGen is 26 in sys_selftest.h. But in the reference manual, it is indicated that the total interval supported is 24.

Updating the value of STC_INTERVAL from 26 to 24, makes the CPU self-test successful on my board.

Could you confirm that this is a bug on HalCoGen?

Maybe this post can help someone with the same issue.

Best regards,

Elieva
