TMS320F28335: CSM Unlock issue

Part Number: TMS320F28335

Hi all,

I have XDS110 debug probe and i am working on f28335 microcontroller. I have an application for f28335. I could program and debug f28335 until settting CSM password. I have to use CSM password with my keys for security reasons. But I can't set the connection with f28335 now. My keys did not change. Normally everything should be okey. After some issue the question pop up on my mind; "What if CSM unlock operation require some additional/different connection with XDS110 debug probe ?" I working on it but i can't get enough info about the case... Any suggestions?

Additinal info: 

I have run led to see if f28335 works. Led is normally blinking so It is working.

I try upload unsecured ram linked application. I can't upload the app and get same error.

The error attached as screenshot.

Thanks in advance.
