Hi .@danielmartynek,

Is there a way to modify DCF clients using DCD tools?

Hi @qingwang_a,

There is S32K3xx_DCF_clients.xlsx attached to the Reference Manual.

You can refer to these excel calculators for MPC57xx, It is similar to the S32K3 DCF.

Here is this C40_Ip RTD example that writes a new DCF record.

Thank you for your reply. Do you have any examples or documentation on using DCD_tool to modify dcf_client?

Hi @qingwang_a,

This is configurable in DCD
