Second Bootloader for LPC54018M

Customer: GZ Comba

Product: 5G RU

Customer is developing a second bootloader for LPC54018M to update the firmware in the internal flash(embedded 2MB/4MB W25Q Flash) through SPIFI0 interface. As per my understanding, SPIFI operations(erase sector, program page,etc) are not allowed while fetching instructions (XIP mode) or data from SPIFI flash. Code required for sending SPIFI commands must be located in on-chip SRAM.

How to create a second bootloader for LPC54018M? Is there any demo code for this feature?
