Hello,
I am using an NXP S32K312MINI-EVB board.
Initially, the board was powered ON and the LEDs were working, but the USB connection was not detected by Windows Device Manager.
I verified that the PEmicro driver is installed. Device Manager shows:
Jungo Connectivity → pemicrovincdrv
I also tested the board with another PC and another USB connection, but the board was not detected.
During troubleshooting, while the board was connected through USB, I removed the J19 and J20 jumpers. The board LEDs turned OFF.
I then put the jumpers back, but now the board does not power on when i tried to give power supply though USB . when I supply 12 V through J1 only RGB led is ON.
According to the S32K312MINI-EVB Hardware User Manual:
- USB-C J9 → J19 = 1–2, J20 = 1–2
- 12 V J1 → J19 = 2–3, J20 = 2–3
I have set J19/J20 accordingly, but the power LED remains OFF.
Could someone please help me determine whether the board's power circuit may have been affected and which test points I should measure?
I can provide photos of the board and voltage measurements at J23 (VBAT), J24 (VBST), J16 (P5V0), J17 (P3V3), and J27 (GND).
Thank you.
Hi
Please do not use a USB hub; connect the USB cable directly to the computer. I recommend connecting via USB 3.0 or Type-C port.
Does the red OSDA_LED D9 light up?
Otherwise, OpenSDA may not work properly, which would prevent the onboard debugger from being used.
Please check the voltage one by one according to the schematic diagram.
Best Regards,
Robin
