UART0 problem for S32K358

Hi NXP,

I met a problem about UART0 debug of S32K358.

We use S32K358 instead of S32K344 on the board. PTA2 is set as LPUART0_RX function and PTA2 is set as LPUART0_TX function. But now LPUART0_RX doesn't work. MCU can't receive any data from PTA2. But LPUART0_TX works fine. It can output logs from MCU. Are S32K358 and S32K344 pin to pin? UART0 of S32K344 works fine with the same setting.

Looking forward to your reply. Thanks.

Hi @CathyX,

Yes, the pinout are pin-to-pin compatible.

Have you tried more boards? There can be an HW issue.

Was the SW for both MCUs built with the same drivers?

Daniel
