S32K116 UART transmit error

BobYan — Tue, 28 Dec 2021 08:24:01 GMT

Hi Ms or Mr,

I used the UART of S32K116 to transmit 15 bytes to other devices. From the oscilloscope, the first three bytes have been transmitted two times.

How could this happen?

Can someone help me?

Hi BobYan,

Please tell us the version of S32DS and SDK. Have you check the release note of SDK whether there is known issue about it?
Please test UART examples in SDK, to check whether same phenomenon occurs. If not, please check what's the differences in API usage.
If you are using S32 Design Studio for ARM Version 2.2, the release note of SDK can be found in this folder: C:\NXP\S32DS_ARM_v2.2\S32DS\software\S32SDK_S32K1xx_RTM_3.0.0

Best Regards,
Robin

Hi Robin,

Thanks for your reply.

The SD32DS version is V2.2, and the SDK version id RTM_3.0.0.

I have checked the example of the DSK, there have no issue which i have met. Because i wanna use the FIFO to send and receive messages. But the SDK have no example of FIFO. So could you provide me an example of UART which use the FIFO to send and receive messages?

Thanks a lot.

BR,
