RTOS/TM4C1294NCPDT: XDS100V2 Ethernet issue

I wonder if you have the reset vector and stack pointer in your project. Did you start by importing the TCP Echo example using Resource Explorer? I highlighted the button that is used to install the project into your workspace in the image below:

Dear Team,

The above tcpecho example code working fine in "stellaris board" ,

But not working in "XDS100v2" when power on/off not wokring,

kindly confirm what needs to be done.

Thanks for quick reply!

Another example code working fine with that XDS100v2 board,

I have search in TI forum (e2e.ti.com/.../213513)
and added startup_ccs.c in tcpecho example but i am getting following error.

tcpecho example out file size is 2.97MB.

"configPkg/linker.cmd", line 189: error #10099-D: program will not fit into available memory. placement with alignment fails for section ".resetVecs" size 0x3c , overlaps with ".intvecs", size 0x26c (page 0)

kindly suggest what change needs to do.

Dear Team

If startup_ccs.c is added we are getting memory overflow error, 

If removing "startup_ccs.c" one time its working once the device is switch off and start then not working

Kindly suggest best solution for the same.

Thanks & regards

What hardware are you running on? Is it an EK-TM4C1294XL launchpad or custom hardware? Can you export a copy of your project to a .zip file and attach it?

Dear Bob Crosby,

Thanks for your reply!,

on the board chip written as "TM4C1294NCPDT1383ADP9WG4". 

Can you please share your mail id.

I sent you a friend request so that you may e-mail me privately through the e2e system.

I think the issue is that you are using 'System_printf()". That function, as defined in your project, only works with an emulator connected. Once you power cycle the device, the emulator disconnects. You should redirect the IO to a UART. Since this is a TI-RTOS application, I am handing you off to someone from that team.

Are you using the TI compiler or the GCC compiler. TI Compiler works fine without emulation attached. GCC requires you play with semi-hosting. For more details look at: http://processors.wiki.ti.com/index.php/SYS/BIOS_with_GCC_(CortexM)#How_do_I_enable_Semi-Hosting_for_Cortex-M_GNU_targets_.3F

Also, are you disabling the watchdog. When you load with CCS, the gel file disables it (or it does for most devices).

Really sorry for the delay reply since i was travelling, TI Compiler only we are using. 

We did not know how to disable the watchdog kindly guide us.

Thanks & Regards

I don't think it is the watchdog on this device unless your software specifically enabled the watchdog. A simple check is to use Code Composer Studio and expand the Watchdog1 and Watchdog2 tabs in the register window. By default, the watchdogs are not enabled and do not even have clocks enabled to them. If this is the case, you will see "Unable to read" for each register as shown below:
