Blinky example on MIMXRT1050EVKB hangs up in rom code when compiled for QSPI flash.

[mmurty]

Hi Everyone,
I am trying to get started with zephyr + NXP's MIMXRT1050EVKB board.
I tested the blinky example with MIMXRT1020EVK board and it worked fine.
Now I am trying to build the same blinky example for MIMXRT1050EVKB board for booting from QSPI flash but I see that the code hangs up in the ROM code as soon as the binary is flashed.

Below is the compilation log:

I am using JLink to flash and debug.
I must be doing some basic stuff wrong as I am new to zephyr. Hence I am unsure whether this is an issue.
Please take a look at let me know your findings.

Just for clarification: I have made hardware changes to the board to boot from QSPI flash and my boot switches are at internal boot settings. I am able to run the blinky example from MCUXpresso IDE (Modified the evkbimxrt1050_flexspi_nor_config.c to hold the QSPI flash configuration instead of hyperflash configuration. This may be the issue here).

It seems that the problem was indeed with the wrong memory configuration. ~/zephyrproject/modules/hal/nxp/mcux/boards/evkbimxrt1050/evkbimxrt1050_flexspi_nor_config.c contains the configuration suitable for hyperflash only. (Same as NXP's MCUXpresso SDK). I replaced the correct configuration for the QSPI flash and then the blinky example works.
I am attaching the updated file for your reference. I think now I should create an issue for this.
