TMS570LS0914: HalCoGen: CPU self-test issue

Part Number: TMS570LS0914
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

Yes, 24 is correct value.

What is the HALCoGen version you are using?

Because on my end i could see 24 only:

I tested with latest HALCoGen i.e. 04.07.01

Hi Jagadish,

Thanks for your answer.

I have the same version of Halcogen as you. After seeing your answer, I recreated the project with HalCoGen from scratch. With the new project the generated value is the correct one!

I guess my project was somehow corrupted.

Thanks!
