Hi @bhavyavyas ,
Thank you so much for your interest in our products and for using our community.
1: Did you use MIMXRT1170-EVKB development board or your customed board?
2: Which SDK demo do your use.
I suggest you can refer to SDK demo "evkbmimxrt1170_hello_world_secondary_core_boot_primary_core_cm7" and "evkbmimxrt1170_hello_world_secondary_core_boot_secondary_core_cm4"
For CM7 project:


For CM4 project:


Please double check CORE1_BOOT_ADDRESS setting in " the evkbmimxrt1170_hello_world_secondary_core_boot_primary_core_cm7"

Wish it helps you.
If you still have question about it, please kindly let me know.
Best Regards
MayLiu
