Part Number: TMS320C6748
Other Parts Discussed in Thread: OMAPL138

Hi,

I want to explore more on power on self test. I have referred the documents on POST. I just need more clarification :

1. Is it possible to add addition code to the existing POST test codes for my requirements? 

2. Does the POST work on FLASHED code because the document mentioned CCS and JTAG and PC under the requirements for POST.

I document link :http://www.ti.com/lit/an/spraas5a/spraas5a.pdf

Thanks and Regards,

Ashwin

    Hi,

    The POST is designed to test your board before board boot-up, see:

    I am not sure what do you mean by: "Does the POST work on FLASHED code because the document mentioned CCS and JTAG and PC under the requirements for POST."

    As you can see from the Wiki above you can flash the POST binary on your board and not use CCS & JTAG. 

    1. Is it possible to add addition code to the existing POST test codes for my requirements?

    Yes, this should be possible.

    Best Regards,
    Yordan
