TMS570LS3137: Prefetch abort in TI FEE

Tool/software:

Hello,

I have a prefect abort while calling TI_Fee_GetJobResult. The FEE library is integrated in the application as per user manual.

I couldn't interpret the fault status value for this prefetch abort it would be great to have a feedback on this. The relevant register after prefect abort is triggered is as follows:

Prefetch abort is not triggered, If the TI_Fee_GetJobResult is invoked in previledge mode. As per the user manual I think TI_Fee_GetJobResult doesnt require raising the privilege.

You are correct reading TI_Fee_GetJobResult doesn't require raising the privilege.

I don't know exact root cause why you are facing this issue, first i would suggest you refer existing examples once, because i never saw this issue in these examples.

You can find one example in HALCoGen itself:

Go to Help Topics section,

Here you can find FEE example with step-by-step procedure:

The other examples are available in below location:
