MC33FS8510A3ES Watchdog config issue

[Makabaka]

Dears:

Issue description:

-two project A and B. developed with same MCU and SBC(FS8510) 

-in order to enter normal mode from debug mode,need to send 6 times WD_SEED to  FS_WD_ANSWER.

-But,  the WD_SEED value is 0x5AB2 all the time in project A. the WD_SEED value changed every times in project B, for example 0xF3BA.

-WD config is 0xB20B and FS_STATE value is 0x2009 in both A and B project.

-why this WD_SEED is different?

Thanks

HI

Two questions for you:

1: you select Challenger watchdog in both project,right?

2:The MCU  send the seed of the LFSR in both projects,right?

after power on reset the default value of seed is 0x5AB2.
