Is this the first time trying to connect to the EVB? Was there any project uploaded to it before?
The board has is brand new and it seems to have some factory-installed programme i.e. the USER_LED_0 color changes by pressing SW5 and SW6
I can see from the picture both LEDs RESET_K3 and RST_OSDA are on. Is RESET_K3 always on when powering the board?
Are you able to measure it? Usually when the reset LED is on, the line is being pulled for a really short period of time periodically, keeping the MCU on reset.
RESET_K3 and RST_OSDA are OFF initially when I connect the board following the power-up procedure. When attempting to debug, the RST_OSDA (and sometimes RST_K3) LEDs turn ON while simultaneously getting the PEmicro Connection Assistant popup.
Also, if I press the SW4 and then retrying debugging, I get this different popup:
Also, measure the voltage sources, if these do not provide the expected value this means that the MCU could be damaged.
I've already tried with 2 different adapters: 12V-4A and 12V-5A, getting same results. The adapter voltage output is stable.
- If you mean the S32K3 MCU getting damaged: The default application (LED color changing) is still working on the board.
- If you mean the NXP K26 getting damaged: I'm still able to upgrade the firmware using the "Multilink Firmware Config Utility" to usbmlacpembeddedens.1098
If you have any external debuggers available (PEmicro, JLink, Latuerbach, etc.), you can try using them instead to see if any connection is possible.
I'll get a JLink next week, along with a new EVB. This time it will be a S32K344MINI EVB.
If there's anything additionally required to identify the rootcause, let me know.

Hi @zaighamkhawaja,
Thank you for the additional info.
Please update me if you can connect with the external debugger.
Does this happen with a blank or an example project? As a last chance, have you tried to attach to the MCU instead of trying to debug/erase?
This leads me to believe either HSE is installed, or the debug port is locked and needs to be unsecured by password or challenge/response. PEmicro provides Python scripts to authenticate the debugger at the start of each session; however, the password is needed.
Last resource can be to swap MCU to confirm if debug interface is faulty, or the MCU is secured/disabled debug pins.
Best regards,
Julián
