LAUNCHXL-F28379D: Could not reprogram the password nor read the flash of the launchpad

Part Number: LAUNCHXL-F28379D
Other Parts Discussed in Thread: SYSCONFIG

Tool/software:

I tried to test dcsm code in the launch pad.First i tried to flash it with only enabling the ZONE 1 Header in the  sysconfig. but i did not enable the ZONE1 LINKPOINTER + Zone select Block configuration box.

I was able to flash to the board once.. but after that i tried to update the password 0,1,2,3 in the ZONE1 LINKPOINTER but could not program the board  It resulted in error 

C28xx_CPU1: Error during Flash programming (Flash algorithm returned error code). FMSTAT (STATCMD on some devices) value = 48. Operation Cancelled (0).
C28xx_CPU1: File Loader: Memory write failed: Unknown error
C28xx_CPU1: GEL: File: C:\dev\PPS\Workspace2CSM\dcsm_security_tool\CPU1_RAM\dcsm_security_tool.out: Load failed.

But when i tried to flash a code without the dcsm option like just led alone i am able to flash it.. but I am not able to locate the code's position in memory.The memory reads as FFFF

How to update the password ? If its locked  how to unlock it?

I tried reading the passowrd location (0x5F016 till 0x5F010 ) It shows all zeros..
