LPUART issue on S32k116

[zzkk]

hello，

I am using SDK3.0.0 for a LIN communication .

I got a problem when I want to turn off peripherals.

The program is stuck in LIN_DRV_Deinit(INST_LIN1)➡LIN_LPUART_DRV_Deinit(uint32_t instance)➡

LPUART_SetReceiverCmd(base, false).

The LPUART_CRTL_RE is 1.When I reset it in Debug，program will runnig normally.

This fault occurred sporadically when the mcu powered on.

I have changed the clock source of LIN from SIRC to SOSC,This fault has been resolved.

I want to know the reason about this.

If you have any ideas,please  answer in the comments,Thank you very much.

Thank  you for your help Lukas. Where can I get SDK 4.0.3 ?

I am using s32ds for arm but I found that i can not add it in.

Do you have a website links about it？

Best Regard,

zzkk

It's not available for S32DS for Arm (which is version 2.2). It's available for new S32DS:

Newest version is 3.5. The SDK can be installed using: Help -> S32DS Extensions and Updates.
