DRA821U: ESM

Hi,

1. What kinds of errors can ESM detect ?

Yes, TRM Section 9.4, Interrupt Sources, has subsections showing the interrupts routed to the ESM module.

• 9.4.1.3 WKUP ESM0 Interrupt Map
• 9.4.2.3 MCU ESM0 Interrupt Map
• 9.4.3.17 Main ESM0 Interrupt Map

2. In the Interrupt map I can not understand the words. Cold you tell me ?

     1)  GASKET

     2)  RTI

     3)  DCC

RTI - The Real Time Interrupt (RTI) module provides timer functionality for operating systems and for benchmarking code.
The module incorporates several counters, which define the timebases needed for scheduling in the operating
system.  See TRM Section 12.10.2.1 RTI OVerview

Gasket - In order to satisfy safety requirements the Jacinto7 family of devices have in-built mechanisms for isolation and freedom from interference (FFI).   The TI Safety Manual contains more information on this.   In more generic terms a gasket is a seal between components.

DCC - Dual Clock Comparator, for safety diagnostics DCC can be used to detect incorrect frequencies between clock sources.  The TI Safety Manual contains further information on this.

 3. In the interrupt map I can see the word "PBIST". I believe PBIST means Programmable Built-In Self-Test ,

     so 

        1) What kinds of test does PBIST do?

               memory check, communication check, etc......

        2) We do not have to develop the PBIST software , is that correct ?

Yes definition of PBIST is correct.  The TI Safety Manual contains further information on PBIST.

Hi,

Thank you very much for your answer.

I would like to know the interrupt for ESM in detail.

The table which shows the interrupt article is described by many deprecated words ,so I can not understand what it means.

If you have any documents which shows the detail.
