errata_PBIST_4() function uses rsvd4[1] for TMS570LS0432 device

Pashan None

Other Parts Discussed in Thread: TMS570LS0432, HALCOGEN

Hello Support,
We are using TMS570LS0432 Corona Device which has only Port 0 for PBIST. There is no Port 1 for PBIST.

Hencec there is no FSRF1 Bit for Corona Device.
But in errata_PBIST_4() within Halcogen 3.08.01, I see that there is a check for pbistREG->rsvd4[1U] for the fault status check.
Can you please confirm if it is a mistake or not because I think that one is for PORT 1?

Thank you.
Regards
Pashan

Hello Pashan,

Sorry for the delay.

You are right, FSRF1 is for port1, and this port is not used on the LS0432. I will check the reason behind reading the pbistREG->rsvd3 and pbistREG->rsvd4 locations and get back to you.

Regards,

Sunil

Pashan,

The rsvd3 and rsvd4 register locations are "reserved" and not "unused". They are used to hold variables and constants used by the PBIST controller algorithms.
