MIMXRT1050 EVKB QSPI flash

Hi everyone,

I've been developing on an MIMXRT1050 EVK(A) board with the QSPI flash and am familiar with using EVK(A) QSPI flash.  I have just received an MIMXRT1050 EVKB board and I have made the necessary modifications to use the EVKB QSPI flash.  Out of the box I was unable to load and debug a program in QSPI flash with MCUXpresso and the MIMXRT1050-EVK_IS25WP064A.cfx driver.  Instead, I first needed to program the QSPI flash with the manufacturing tool.  After programming the QSPI flash with the manufacturing tool, I was able to load and debug programs in flash.

Is this expected behavior?  I need to know because this platform will be used by numerous engineers and I need to provide instructions.

Thanks.
