Issue with cc2538 UART

PB_21

Other Parts Discussed in Thread: CC2538, Z-STACK

Hi,

I am using zstack 1.0.0 version and I am facing a problem with the UART. I have initialized the UART and when I am trying to write the messages through the UART I can see the messages displayed on the LCD of CC2538 on the serial monitor apart from the messages I write using the HalUARTWrite(). What could be the issue? is there any changes in the configuration that I should take care of?

Thank you

Don't understand your question well. Can you see anything output from TX pin when using HalUARTWrite?

I see the messages displayed on the LCD as the output from TX pin.

Do you mean you see what you send by HalUARTWrite also show on LCD?

I see whatever is displayed on the LCD like the Zigbee coord, Network ID:FF54, 00124B00040F05BF when UART is used.

Try to disable MT_TASK in your compile options.

I am not able to download the program into cc2538 without MT_TASK.

I get the following error if I do so

Error[Li005]: no definition for "debug_str" [referenced from C:\Users\IAR1\Desktop\Z-Stack Mesh 2\Projects\zstack\Samples\GenericApp\CC2538\Coordinator\Obj\ hal_lcd.o]

You can comment out debug_str in hal_lcd.c to solve the issue.
