TI-RTOS example tcpEcho - EK-TM4C1294XL nor run when power applied - run when debug

Pat We

Hello

I have a little question, this is the second TI-RTOS project (first already running on tiva 123 MCU target product).

This time code is ready to be moved to the target hardware but how to make it running when power is applied. It only seem to start the code execution when I start the debug session and code keep running when debugger is disconnected. But when I reapplay the power device wont start.

I have observed that behavior even with tcpEcho example with no changes to code. Import, debug and everything runs ok. But when I take the board and apply the power only (via debug or OTG - jumper selection) the code wont start. When working with TI-RTOS for Tiva 123 that wasn't the case.

I don't even know where to start solving the problem, is it the linker script? I have changed from debug to release and used the same linker script no help.

Regards

Hi,

Just make sure if you have read and modify code according to the workaround:

Hope it helps.

Hi Pat,

The usual cause for this problem, is that you don't have a startup file, or wrong settings at linker file at your CCS project.

Hi Pat,

what version of TI-RTOS are you using? Does a non-Ethernet example for you on your custom board?

I'm trying to understand your problem. I think you're saying that you can run an example when you load and run it through the debugger, but the same example doesn't work after you press the reset button without the debugger being connected to the MCU. Am I missing anything else?
