Dear Arashjot,
This issue is seen in R2014b, because the Freescale Cup Companion App checks if the Embedded Coder Support Package for Freescale FRDM-KL25Z Support Package is installed and if it cannot find the support package it disables several buttons and provides you with a way to install the support package. It checks for the support package by getting a list of all installed support packages and then comparing their short names against the short name it thinks the support package should have. This "short name" was changed in R2014b, so the App does not recognize that the support package has been installed.
A fix has been created, and should go up soon (along with some other enhancements to the App, including an update feature), but if you would like to get started right away, here is the workaround:
1. Open the App then close it. (this makes sure the App code is on the MATLAB Path)
2. Open the main App code by executing the following command in the MATLAB Command Window:
edit(which('FreescaleCupApp.m'))
3. Edit lines 106 and 145. These lines should be:
isSP_installed = any(arrayfun(@(sp)strcmp(sp.Name, 'Freescale FRDM-KL25Z'), info));
Which needs to be updated to:
isSP_installed = any(arrayfun(@(sp)any(ismember({'Freescale FRDM-KL25Z', 'Freescale Kinetis Microcontrollers'}, sp.Name)), info));
This fix will allow the App to work for both R2014a and R2014b.
4. Save and close the file and execute the following command in the MATLAB Command Window:
clear classes
5. Reopen the App to see the changes.
