AM2634: ASIL Rated MCAL is Available for AM2634

Can anyone reply to my queries ASAP

Hello,

2. Yes, ASIL rated MCAL is provided for this controller.
For remaining questions I have added relevant experts, please expect a response soon.

Thanks,
Gunjan

Hello Prajakta,

1. This controller have 4 cores. Out of 4, any specific core is assigned for safety ??

No there aren't specific cores for safety. But if using Lockstep than R5FSS0 Core 0 and Core 1 are associated with each other and R5FSS1 Core 0 and Core 1 are associated with each other.

3. Is there any specific PMIC IC need to be used for controller power supply monitoring ?

No there isn't a specific PMIC required, but any PMIC selected needs to supply enough voltage/current for each rail and manage the bring up of the device per specifications for power sequencing. These are all provided in the datasheet with more details in the TRM.

If you want a part recommendation of a couple devices we commonly use I can provide those.

Prajakta Dange said:

5. Does this controller is capable for mathematical operations (DSP support)??

There is not an embedded DSP in the device but instead there is a Trigonometric Math Unit (TMU) module and the device is floating point as well.

Prajakta Dange said:

6. Is there any provision to measure process clock utilization ??? 

I am not fully sure what you mean by clock utilization but there are means to benchmark your application - I would need to loop in another expert to go into detail on that, or you can make a separate thread about that specific topic.

7. Is there any provision to trace/ monitor the software/code ??

Yes JTAG Trace is supported and the recommended trace probe currently is Lauterbach's.

9. What are specific configuration to run code in specific core of controller ?

Can you elaborate what you mean by this?

Prajakta Dange said:

10. What are debugging tools/procedure available for on field issues ?

Can you elaborate what you mean by this?

Also will these devices be put into a field secured state as they are security enabled and can be placed in such a mode?

Which ASIL rated ??

4. What are ASIL dependency for controller w.r.t scheduler, RTOS without which safety is not compliant ?

8. Whether PLS tool is compatible for processor utilization measurement with this series for TI controller?

These 2 queries are still unresolved.

Thanks for your reply.

9. What are specific configuration to run code in specific core of controller ? 

==> Suppose I want to write some part of code in particular core out of 4, then how to do configuration for the same . 

10. What are debugging tools/procedure available for on field issues ?

==> If product is on field. Some issue occurred with product, then what are the methods to debug ??

6. Is there any provision to measure process clock utilization ??? 

==>What are the methods/ process to measure how much controller is loaded, how clock utilized , etc ??

You can select specific cores to access and load code into.

This will depend what security measures are in place on the device. Also it will depend on system design such as do you intend to put JTAG access on your board. We can get a security expert to help comment on this further.

It is certified for ASIL D, more details can be found here Functional Safety for AM2x and Hercules Microcontrollers

Sorry I do not understand this, could you please elaborate?

No, this isn't compatible.
