Does S32 Debug Probe work with S32K144EVB-Q100 / S32K144 development board

Hi,

I am trying to use an external NXP S32 Debug Probe with an S32K144 development board / S32K144EVB-Q100 in S32 Design Studio 3.6.1.

My setup is:

Board: S32K144 development board / S32K144EVB-Q100
Debugger: NXP S32 Debug Probe
Connection: S32 Debug Probe connected to J14 using the 10-pin SWD/Cortex connector
IDE: S32 Design Studio 3.6.1
Device: S32K144
Core: M4F
Interface: S32 Debug Probe - USB
Init script: s32k14x_generic_bareboard.py
JTAG/SWD speed tested: 500 kHz
Delay after reset tested: 200 ms
J104: 2-3
J107: tested with external/board power
J14 pin 1 / VTREF measures about 5 V

The probe is detected by S32 Design Studio over USB, but Test connection fails. When I try to start debug, I get:

Failure during execution of python script

CCS: subcore error during multicore operation

Error code is 1338

My question is:

Is the NXP S32 Debug Probe compatible with the S32K144 development board / S32K144EVB-Q100 when J14 VTREF is 5 V?

Or does the board need to be modified/configured to run the target/debug interface at 3.3 V before the S32 Debug Probe can work?

I would like to know if this is a configuration issue in S32 Design Studio, or if the S32 Debug Probe is simply not suitable for this board in its default 5 V configuration.

Thanks!

Hi @Bridgebranch

Yes, the board should be configured for a 3.3 V domain, as the S32 Debug Probe supports system voltage levels only within the range of 1.2 V to 3.3 V.

I suggest taking a look at the following link, which demonstrates how to modify the board: Updating the S32K144EVB to Switch between 5V and 3.3V Logic Levels.
