i.MX RT1020 FlexSPI boot from non-standard flash device

I'm designing a custom board with the i.MX RT1020 processor. I'm using ISSI IS25LP080D flash device. So far I've been able to program the flash device (I've done this through command line instructions using sdphost.exe and blhost.exe over UART as well as NXP's MCU Boot Utility v1.1.0). However, when I try to do an internal boot (BOOT_MODE[1:0] = 10b) the application software does not appear to be running.

 

I think there's something in the Flash Device Config Block that needs to be edited since I'm using a different flash device than the EVK board (IS25LP064A), specifically the LUT part of the block. I'm unsure how to proceed and was wondering if there are any helpful articles or tips on how to configure the board for this flash device.
