Functional Safety implementation example on S32K1xx

[wei_w_he]

Dear Officer,

NXP has the Safety manual explaining the methods for implementing the FS feature on S32K1xx, Do NXP has some example (source) code?

Thanks and best regards

Hello He Wei,

Sorry for the delay, regarding the examples codes; We created an app note that helps to understand the examples and how is implemented each assumption but this is a draft version and is attached to this post, also you can find the examples in this link.

Best regards,

Oscar Hinojosa.

Hello Oscar,

I'm a bit confused about SM_047 in the S32 Safety Manual. The cookbook says that this assumption is fulfilled if it is ensured that no debugging device is connected (essentially a process barrier, maybe also a physical one). The following sentence states that debugging should be disabled in the field. Is this already achieved by not connecting any debugging devices (i.e. essentially by the first sentence) or does this second sentence imply that an additional HW-barrier is also required? Specifically, the safety manual states that JTAG-TMS should be pulled low. If that's the case however, it looks like it's not possible to programm the controller anymore? We use SWD-DIO to programm the controller during production. Once fully assembled, the controller is in its casing and this interface is physically not accessible anymore. Would that satisfy the assumption, even if JTAG-TMS is not permanently pulled low by a resistor?

Best regards

Matthias

Dear Officer,

I can't log in the below link to get the example code:

https://bitbucket.sw.nxp.com/projects/AAG/repos/s32k1xx_safety_cookbook/browse

Is it still available? Or I didn't get permission to log in that link? Can share the example via other way?

Tks and best regards
