iMXRT-1064; booting directly to active firmware in internal FLASH

Hello!

I'm working on a project where we use iMXRT-1064. I have a question regarding Firmware swap feature that is introduced in document AN12255 and AN12240. This question is also linked to discussion thread on the same topic (https://community.nxp.com/t5/i-MX-RT/iMXRT1064-Issue-with-firmware-swap/m-p/1345041#M16437)

The question is; Is it possible to set iMXRT-1064 to automatically boot directly to a predefined (active) FLASH section, so that the API function call "bl_firmware_switch()" would not be needed?

An example; the internal FLASH is divided into two 2 MByte sections (0 and 1), and the active (latest) firmware has been programmed into section 1 (address 0x7020 0000). Now, the device boots up on section 0 (0x7000 0000) and from there we have to jump to section 1 in order to run the latest SW image. Is there any way to make the processor to boot directly from section 1 so that the jump command would not be needed?

Thanks & best regards,

Jari
