Hi,

I implementted LPUART function with S32KDS and SKD_S32K14x_09.

But the UART function does not work.

I attched my project.

Please review my project.

Hi,

I looked at you project and question is - how do you find out that UART doesn't work? In your project is only UART init function - returning STATUS_SUCCESS.

Please look at lpuart_echo_s32k144 example for reference:

Hope it helps.

Dear Jiri,

Thanks to you, I can see UART message.

I have two questions.

1. How to get the S32K14x_RTM_SDK_V2.0.0?

2. How to use UART interrupt?

I use LPUART_DRV_InstallRxCallback. But I think Interrupt does not be clear.

Can you give me the guide of interrupt of uart?

Best regards,

Byungju.

You can click on this message box - probably appeared after S32DS Launch to update S32DS:

If you don't see such message - update your S32DS Installation manually - on main menu bar click on Help -> Install new software

Click on available sites, choose PEMicro and S32DesignStudio, click on OK

In Work with row select All Available sites - and when updates will be found - click on next.

As I mentioned above - best starting point is LPUART echo example - this example is available in any SDK version and uses interrupts.

Hope it helps

Dear Jiri,

I have two questions.

1. How to import S32K14x_RTM_SDK_V2.0.0?

I get the samplecode with S32K14x_RTM_SDK_V2.0.0.

But I don't use S32K14x_RTM_SDK_V2.0.0.

So I don't use some funtions.

2. How to clear UART interrupt?

When I test send uart message of very big data size.

Because interrupt does not clear, MCU is reset because of watchdog time out.

Best regards,

Byungju.
