Serial Interface doesn't work - S32K3x4-Q172

MVR — Fri, 16 Sep 2022 20:13:57 GMT

Hello,

I'm using:

S32K3x4-Q172 and S32K3 RTD AUTOSAR 4.4 2.0.1 D2207.

I'm testing the serial interface (LPUART6) but it doesn't work. I can see the signal in pin 2 of J44 when I send data in TX line but on PC I can't see data arriving on serial software. The baudrate is ok and the port of board appear correctly on device manager. Also I check the power supply of NTS0102GD and everything is ok.

It must be problem with MK26FN2M0VMI18?

Thanks

Hi MVR,

Seems that the problem is related the OpenSDA firmware of K26. Please refer to the discussion in: request K26's OpenSDA firmware on the S32K3X4EVB-Q172

Maybe PEMicro will send you the latest K26 Embedded Multilink firmware with full virtual serial port support.

Best Regards,
Robin

Hello Robin,

I talked with pemicro team and updated the FW.

But it doesn't work yet, I can see the signal as I said on TX line but on serial software it doesn't appear...

Do you have any idea how can I fix it?

Did you install the Virtual COM Port Drivers ?
