Why is the LED not blinking when I try to reset the TI C2000 F2837xD or F2838x target when loaded with the Blink_LED shipping example from Simulink?

This issue is applicable to multicore targets like F2837xD and F2838x. Follow the below steps to resolve the issue: 

1) Ensure that the Simulink model is loaded in all the 3 cores of F2838x (2 cores for F2837xD), even though a single core is used. This is necessary because the initialization routines in the code generated from the Simulink model are different from manual code or TI example code. Otherwise, this may lead to synchronization issues between the CPU cores and the build may not run as expected. 

2) All the CPUs need to be loaded with executables (.out file) from the same MATLAB release. 

3) Ensure that the same peripherals, such as GPIO pins, are not used by multiple cores. If the same peripherals are used by multiple cores, the build may not run as expected. 

Hardware Limitation for F28379D Launchpad: 

Using the reset on F28379D launchpad resets only CPU1 and not CPU2. This is a hardware limitation for the F28379D launchpad.
