Hi Dion Sosa,
Thanks for your reply.
Q1) Do I do anything for boot header?
-- Yes, using instructions to create a corresponding boot image based on the bin file.
Q2) Is there a simplified list I can follow on the website?
-- Actually, the AN12108 is very simplified.
Q3) I never get a bin file either using IAR or MCUXpresso.
-- In the IDE's guide, it describes the steps to generate the bin file and please follow them.
Regarding your issue, if you assue that your hardware setting is 100% correct.
I find you use the MCUXpresso IDE, please check the appropriate flash driver (MIMXRT1050-EVK_IS25WP064A.cfx) is selected as the Fig 1 illustrates.

Have a great day,
TIC
