How to erase/write the internal flash in LPC 54S018 part

[richardchennv]

Hi all, any link or example code on how to erase/write the internal flash in NXP LPC 54S018 part? Should I use ROM service or BSP library? Any example project would be great.

Thanks for your help!

Hi richardchennv 

LPC54S018 doesn't have internal flash, user needs to connect external spifi flash.

Please check this thread for how to erase and write spifi flash
