TMS320F28388D: Safety Test for ROM Prefetch Functionality

Part Number: TMS320F28388D


Hello,

I am currently trying to implement a ROM4 safety test for the TMS320F2838D. I want to test the ROM prefetch functionality. The Function Safety Manual (https://www.ti.com/lit/fs/sffs022/sffs022.pdf, chapter 6.6.16) says it can be implemented like the FLASH8 prefetch test. In this flash test a test function is run to measure an increase in execution time. To test the prefetch of the ROM I think I must run some suitable code from (Boot?) ROM, but I can not get there my code, so I don’t know how to do it. Has anyone some experience with this?

Thank you.

    I tried out a lot of different methodes in the meantime, but I coud not managed it. Are there some functions in the ROM that are accessible for me, where I could try to see an difference in timing with disabled prefetch?

    (I'm sorry that I'm speaking to you directly, but unfortunately I haven't received a response yet and I don't know how to proceed. Maybe you could help or know someone who can help me, thank you)
