[Furkan_26]

I must add that this excel file generates wrong checksum values for some srec records, and I use them via a script I have wrote by using Python. 

Could you verify if my instructions are correct or not? If I embed the corrected srec to the mcu, is it going to work? Can I show if STCU2 module is working correctly via a manual or a paper? Because as far as I understand, there is no way to corrupt the device without actually harming it. 

Thanks in advance.

Hello,

Well, programming the STCU based on your own configuration.. I would not recommend doing that unless you have deep knowledge on STCU mechanism and lot of testing possibility.

Could you verify if my instructions are correct or not?

I have attached reference script. Furthermore checksums depends on device cut, which you do not share with me. So make sure you have the same as I. -> 3N45H

If I embed the corrected srec to the mcu, is it going to work?

Cant say. But if it is correct STCU configuration validated by NXP, it will.

Can I show if STCU2 module is working correctly via a manual or a paper?

Sorry, I do not understand this questions. STCU is HW module operating dependent on voltages, memory conditions, peripheries, etc...

Because as far as I understand, there is no way to corrupt the device without actually harming it.

By programming STCU DCF records, you cant harm device. But messing with UTEST flash, you definitely can corrupt device.

I suggest you to read AN:

@petervlna Thank you for explaining.

I must validate my configuration work somehow for certification. So ı need some result of testing by you. 

how can I run the cmm file? Im using PE micro FX debugger is that important for implementing that script?

I meant the checksums the excel calculates.

Hello,

Dont know which kind of certification standard you are talking about. This device is ASIL-D ready.

Anyway, we are not able to share any resources regarding testing process here on public community.

For such communication you will need NDA and rise a ticket at NXP.com

how can I run the cmm file? Im using PE micro FX debugger is that important for implementing that script?

You will need Lauterbach debugger in order to use cmm file.

I have shared it as an example of configuration. You can port the DCFs for your PE which use S3 records format.

I meant the checksums the excel calculates.

Excel should be fine. But I was talking about BIST MISR checksums. Those are MISR trough registers and they differ based on silicon cut. So make sure you have same device cut.

Otherwise when the BIST finish logic tests, it will fail as the expected and calculated MISR will not match.

Unfortunate I do not have PE script for BIST programming. Not even sure if PE allows scripting.

Best regards,

Peter

Hey @petervlna and @Furkan_26,

I also had a similar problem about the excel. 

So make sure you have same device cut.

How to check this? What is a device cut?

Hello,

You can read MIDR register.

Or simply have a look at device package:

Best regards,
