LPC1788 write external flash

Hello,
for my job I have to design a project based on LPC1788 where some data are received by UART and then must be written in memory.
Initially I wanted to use an external SPI EEPROM but because of data size (several Mbits) I need to use an external flash memory connected by EMC.

In the past I have used EMC for SDRAM, never for Flash. How can I write a single buffer of data into external flash? I don't want to write low level read/write functions from external flash because it is complex and I wonder if there is a simple way

Best regards

Flash are written on pages, unlike SDRAM. For examples, to configure the flash, I found these two post that may be helpful:
Spansion EMC NOR Flash on LPC1788 - NXP Community
EMC + LPC1788 + s29gl064 norFlash - NXP Community
