Dear all,
I am trying to configure the Control Law Accelerator (CLA) for my LAUNCHXL-F28379D launchpad, based on the TMS320F28379D microcontroller. I am getting an error when trying to compile my model:
The "Main Routine - CPU1" works fine, as it was already tested. I included the "CLA Task Trigger", which is triggered by ePWM1. The variable that is passed from "Main Rotine - CPU1" to "Auxiliary Routine - CLA1" is only "theta_e" (for now), and it is defined in the main level by the "Data Store Memory" block. "System Initialize" only turns on two pullup resistors, and have no relevancy here. Excluding the right-side of the model (CLA Task Trigger, its subsystem and the global variable), the model works as intended.
By adding the CLA, even searching a lot, I could not find a solution to the problem caused. The section of the Diagnostic Viewer that describes the error is the one that follows:
"C:/Users/Gabriel/Documents/MATLAB/C2000_Programming/BOOSTXL_3PhGaNInv_Test/BOOSTXL_3PhGaNInv_Test_CPU1_L4_ert_rtw/cla_task.cla", line 1: fatal error: cannot open source file "cla_header.h"
1 catastrophic error detected in the compilation of "C:/Users/Gabriel/Documents/MATLAB/C2000_Programming/BOOSTXL_3PhGaNInv_Test/BOOSTXL_3PhGaNInv_Test_CPU1_L4_ert_rtw/cla_task.cla".
Compilation terminated.

It seems that the file "cla_header.h" could not be opened. I tried to debug it myself, and have some useful information that might be helpful:
I have worked for several hours in this issue, but it is still persistent. Could anyone help me? How can I effectively implement the CLA in my F28379D launchpad?
Best regards,
Gabriel
