TMS320F28377D DCSM is used but caused CLA worked abnormal!!! pls tell me how to solve this issue? tks!

Dear all:

       When I use TMS320F28377 ,there were some issuses as below:

1st:  I want to use DCSM block to set a password for  on chip  codes; cmd  file configured as cmd-1 and cmd-2.jpg DCSM file configured as dcsm-block1.jpg and dcsm-block2.jpg

cmd-1.jpg

cmd-2.jpg

dcsm-blcok1.jpg

dcsm-block2.jpg

2st :   CPU was working normal,  CLA was abnormal: interrupt is not work,   but MIFR reg:bit0   of CLA  was set to 1, it seems cla is working!   but  the address  in MPC reg   can't point to correct task address.

          because of the task address is not correct ,the interrupt function can't be executed.

        pls give me some advises ,thanks!
