Is it important to keep flashloader in external flash

Hello

I'm using the MIMXRT1011CAE4A processor with the MCU Expresso IDE tool. I aim to boot the processor from the external NOR flash (MT25QU512ABB) through FlexSPI. I'm wondering if it's necessary to load the flashloader binary (ivt_flashloader.bin) into the RAM.

I've generated a binary file of my application code, which includes boot data and the IVT structure alongside the application code. Should I directly flash the program image to the flash memory, or do I need to load the Flash loader first and then repeat this process?

Currently, I'm simply writing the program image (which is the binary file of my application code) through file handling functions in the MCU Expresso IDE tool. Could you please clarify and explain the required process to boot my processor from external flash?
