Hi @Newton829 ,
Thanks for your interest in NXP MIMXRT series!
I have tested with RT1170-EVKB and SDK 2.15.000. The demo is evkbmimxrt1170_sdcard_fatfs_freertos_cm7. It works well on my side.

I suggest you confirm the boot options confirguration,SW1:0-0-1-0 and SW2 all zero.
Hope it helps!
Best regards,
