Hi,

I'm getting the following errors on compiling my project:

I'm attaching the screenshot of my linker .cmd file below:

    Hi,

      Do you know how big is your program? You can check the map file in the Debug directory. See below. I see you start the FLASH section at 0x84000. That is more than 0.5MB of space you are not reserving for your code. Why do you want to do that? If your code is more than 0.5MB then it will not fit between 0x84000 and 0x100000. One more comment is that you declare the FLASH memory as (RXW). You should change to (RX). See one of the TivaWare examples for reference.

    I did the suggested changes. Following is my map file.

    My updated linker.cmd file is:

    The error now is:

    Hi,

      Can you try two things:

     - Try to import an existing TI-RTOS example. It should work out of box. Use the .cmd file that is used by the example. The best approach to start a new project is to use an existing example as a starting point where all the system variables, .cmd and etc are already setup for you. I'm not sure where you got your initial .cmd file from. You will have a much easier time if you start from a working example. 

     - Or try the below .cmd file. This is an .cmd for one of the TI-RTOS examples.
