To enable Trace pins in S32K312EVB-Q172 Evaluation board

KIRANSRI — Wed, 02 Aug 2023 04:42:53 GMT

Hello,

In order to employ trace configurations, we are using the S32K3X4EVB-S172 Evaluation Board.

We're having trouble figuring out how to enable the trace pins. We also referred to the Customer Evaluation Board for S32K3x4 MCUs Hardware User Manual.

Could you kindly propose a solution to the above?

Hello @KIRANSRI,

Depends on the debugger you use.

SEGGER solution is here:

https://wiki.segger.com/NXP_S32K3xx

There are projects for the S32K344 part.

This is Lauterbach script that enables the ETM and TRACE pins on S32K344:

;this script config s32k3 GPIOs for TRACE (trace clk, d0~d3), and enable ETM trace ;application code should not change these GPIO MSCR registers ;Set SWO override needed for TPIU trace ;Data.Set EDBG:0x40000604 %Long 0yXXXXxxxxX1X0xxxxXXXXxxxxXXXXxxxx d.s SD:0x40290558 %Long 0x00200107 ;PTG6 as TRACE CLKOUT d.s SD:0x4029055C %Long 0x00200107 ;PTG7 as TRACE D0 d.s SD:0x4029057C %Long 0x00200107 ;PTG15 as TRACE D1 (GPIO207) d.s SD:0x40290580 %Long 0x00200107 ;PTG16 as TRACE D2 (GPIO208) d.s SD:0x4029053C %Long 0x00200107 ;PTF31 as TRACE D3 (GPIO191) SYStem.CONFIG.CONNECTOR MIPI20T SYStem.Option DUALPORT ON SYStem.MemAccess DAP TPIU.PortSize 4 TPIU.PortMode Continuous ITM.DataTrace CorrelatedData ITM.ON ETM.Trace ON ETM.COND ALL ETM.ON Trace.METHOD CAnalyzer Trace.AutoInit ON ;CAnalyzer.AutoFocus Trace.TraceCLOCK 44MHz Trace.THreshold 1.5 ;for a specific Trace.List window, use the command "Trace.List /Track" can link the list window with the Chart window.
