Problem in Receiving Message

Arun07837 — Fri, 17 Dec 2021 06:10:51 GMT

Hi, i am using s32k148 evaluation board and flashed a sample code of lpuart_echo example code. If i try to transmit and receive the data, the data is getting transmitted but we are not receiving any data.

Connections Made:

Using LPUART1

PTC6-RX connected to TX of TTL Converter

PTC7-TX connected to RX of TTL Converter

Evaluation Board Jumper Connections:

J22: 1,2

J7: 2,3

J8: 2,3

J18: 2,3

I have attached the snapshot of the Result that we are getting in DOCKLIGHT tool. If we send "Hello Board" message we are not receiving any reply back from the board. We are not receiving RX message in the tool

Please let me know what connection we are missing and what is causing issue in Receiving the message. If any board connections are wrong or anything we are missing.

Hi@Arun07837

I checked your settings,these should be right.Did you set the baudrate wrong?

For this example it is necessary to open a terminal emulator and configure it with:
- 115200 baud
- One stop bit
- No parity
- No flow control
- '\\n' line ending

BR!

Jim,

Hi@Arun07837

Please check if the correct port is selected.

You can also use an oscilloscope to check the PTC6& PTC7.

BR!
