Dear, We see from ON77P version RM as below, PTC3,PTC2 do not have LPUART0 function

、

But for the latest S32K RM from official web, it say that we need double check IO Signal Description Input Multiplexing sheet(s),

We could see that PTC2，PTC3 could support uart feature as below, could you help check whether S32K144 PTC3, PTC2 pin have LPUART0 function?

Hello,

0N77P is cut 1.0 and I recommend you to not use this cut. Use cut 2.0 (0N47T), which is newer and many things are fixed there. Reference manual for S32K placed at NXP website is determined for the newer cut (0N47T) and this supports LPUART at PTC2/PTC3.

Regards,

Martin

Dear,

Current S32K 0N47T have below bug for LPUART0,

e10656: LPUART: The RXD pin Active Edge Interrupt flash does not assert when active edge is detected.

Whether S32K14x_SDK_EAR_0.8.3 have fixed this bug?

Hello,

for S32K144 microcontroller there is SDK RTM 1.0.0, so SDK EAR 0.8.3 for S32K144 will not be updated anymore. Please use the RTM 1.0.0.

Regards,

Martin
