Problem with receving using UART in s32k144 board

Ramsai — Thu, 29 Dec 2022 08:45:25 GMT

Hi,

Iam working on a project where I need to use UART for communication. while I tried the examples of the UART Iam able to transmit the data but not able to receive the data.

While debugging I got to know that receive status is always busy.

Any suggestion to clear the issue?

MCU-S32K144

IDE-S32KDS 2.2V

Regards,

Ram

Hi,

if you refer to demo example (pluart_echo) it is written in the way the received chars are stored into user buffer and the reception stops when newline character (\n) is received or the buffer is full, then received data are echoed back. You can check if buffer is filled within debugger.
