F28035 KIT debug issue

I am using experimenter kit for F28035. I tried few of the examples in RAM and observed as follows.

If you load .out in RAM and hit "Run" it works every time. If you hit  "reset CPU" and then "Run" it does not work. It gets stuck at

forever.

I have loaded LED blink in flash. Now whenever the debugger is telling me that PC is stuck at above location for any example code in RAM the KIT runs LED blink program from flash. If by any chance you have the same program in flash and RAM you will be confused what is going on.

Is it some config issue I am missing ?

    It is Ok. There is no errors or issues. When You do CPU Reset and then Run - CPU will start from the beginning(i.e. bootloader). Bootloader can be configured by 4 GPIO pins to tell DSC how to reach executable code. There is some variants, like Flash boot, SPI boot, Parallel boot and so on..... I think Your DSC(bootloader) is configured to run from Flash. And after Reset -> Run - You will go to program in flash. Load program -> Run works without bootloader, and CCS sets PC to correct address.

    I tried the example project and my own projects which work well on the other board. Do I have to do any special configurations to use this Experimenter's Kit? 'Cause I get the same result either I load it into RAM or FLASH...

    I understand that it must be something very sipmle, but I don't know what to do. Will appreciate any help!
