DCF Clients file?

[Trevor_Meyer]

Hello:

We are trying to disable lockstep mode on the K344 and saw a reference in the S32K3 RM to a dcf_client_utest_misc[LOCSTEP_EN] bit. The RM says to reference the "DCF Clients file attached to this document" for more information.  Where would we find this DCF Clients file for the K344?

Thanks,

Trevor Meyer

Hello, I had the same issue: now I found it in the attachement of pdf.

Anyway, in my case I need to edit the value of UTEST_MISC.

How to modifiy it? The attached excel inside the pdf says "Not memory mapped"

Hi,

yes, the switch can be done using DCF record – UTEST Miscellaneous Register. You can take a look at file S32K3xx_DCF_clients.xlsx (attached inside the reference manual), tab Utest DCF Client Register Bits. It’s necessary to load new DCF record where the LOCKSTEP_EN bit will be cleared.

BR, Petr

Thanks so much. Now I see the attached file. I will take a look at that.
