TMS320F280025: the program cannot work after secure the device by using UNIFLASH

Part Number: TMS320F280025
Other Parts Discussed in Thread: C2000WARE, UNIFLASH

Hi Team,

hardware: https://www.ti.com/tool/LAUNCHXL-F280025C

demo: C:\ti\c2000\C2000Ware_4_03_00_00\driverlib\f28002x\examples\led --> led_ex1_blinky (Build configurations: CPU1_FLASH)

https://www.ti.com/tool/download/UNIFLASH/8.3.0

The board can run the program normally until I changed the LINKPOINTER and CSMPSWD by using UNIFLASH:

After I changed these options, when I press the load button, the image load successfully and the led on board blinky. Then press the RST button on board or re-power-up the board, the led doesn't work, until re-load the image again.

I guess the reason is the program doesn't contain the PSWD, it cannot pass the PMF, so it is blocked during BOOT. Does this correct? Could you please take a look and explain it? I cannot found the related document.

Thanks & Regards
