RTOS/DK-TM4C129X: TCP Echo IP address unknown

Peter Borenstein

Part Number: DK-TM4C129X

Tool/software: TI-RTOS

In the TCP Echo project for the DK-TM4C129X dev-board, the readme.txt says "the IP address is written to the console".

What is "the console"? I can't see what IP address the board is being assigned via DHCP.

The dev-kit comes with a screen, but nothing is printed on the screen. In fact, none of the screen code seems to be in the project. I verified the screen works by loading another example project.

Hello Peter,

Typically anything that refers to a 'console' means a UART terminal. I recall the UART terminal printing out the IP address on that example. Please give that a try, and if that doesn't work then let me know and I'll flag down someone from the TI-RTOS team who would know more about the documentation.

To keep things simple, I switched to the EK-TM4C1294XL board. The DK-TM4C129X has two USB ports and I want to keep the variables to a minimum.

This board comes out of the box with the qs_iot example project. This works. The qs_iot prints the IP address at the start and then gives me the option to play tic-tac-toe.

The tcpEcho_EK_TM4C1294XL_TI project gives no print out on the terminal. I swapped back in forth between the projects and the qs_iot works every time.

The qs_iot UART code is apparent: UARTStdioConfig(0, 115200, g_ui32SysClock);

The tcpEcho project seems to lack any code to turn on the uart in the .cfg or source.

The tcpEcho project is more important because I want to use TI-RTOS.
