How to recover the UART from Framing error FE or Noise Error NE on kinetis KV10

[amerzater]

Hello there.

I am working on a new design using Kinetis KV10. I realized that once my UART has suffered from Framing error the reception is cutout and no more data is acquired despite the recovery of the rx signal after a while...

could you please advice?

LIN Break Detection is disabled: S2[LBKDE] is set to zero

DMA based reception is being used.

Hi Amer Zater ,

   When you frame error happens, do you clear the related errors?

   If yes, after you clear your error flag, and your UART bus is also correct, when you send the UART data to the KV10, you said it can't receive the data, what's the detail errors? Please debug it, and check the uart status register,then share the result with me.

   You can don't use the DMA at first, when your UART works, then you can add the DMA again.

Any updated information, please kindly let me know.

Have a great day,
Kerry
