Updating linker file for f28027 to calculate RMS using simulink

Other Parts Discussed in Thread: CONTROLSUITE

Hello, 

I am attempting to create code using Simulink for my launchpad f28027 that will determine the RMS of an incoming voltage. I've posted an image of my code:

The code samples from an ADC block, stores the values in a buffer and sends the vector into the RMS block, which should return the RMS of the sampled voltage. In order to get sensible values, I need to have a large enough buffer of points to provide to the RMS block. However, I have found that I cannot set the buffer size to anything larger than 256 samples (I am hoping for at least 1000 samples). As soon as I increase the buffer size to anything greater, I get an error, which terminates the build and tells me that it "Failed to generate all binary outputs." In going back through the diagnostics, I think I have found the error that is terminating the build. It shows up as one of these two:

Error 1:

Error 2:

People have recommended booting from flash and updating the linker file. I have checked the "Boot from flash" option in the build parameters of the model configuration and it does not seem to make any difference. The other recommendation I got was to update the linker file. I found the linker file and read through some of the documentation online and I am finding it very difficult to understand what changes I need to make and how to make them. Could someone possibly explain how to edit the file to accommodate approximately 1000 samples? I have posted a copy of my linker file below.

Thank you very much in advance for all of your help!
