LPC43xx Fireware update by IAP

Are there any routines to demonstrate how to upgrade the firmware through the IAP?

LPCOpen has a example - examples\periph\flashiap.

But this routine doesn't solve the problems I'm having right now.

My firmware needs to use the dual BANK address space in lpc4357.

And the firemware file format is BIN,it is read by USB from U-Disk.

So,when i read a section BIN file,i don't know write the program into which flash sector of dual BANK.

In other words, when I write the entire BIN file to flash, the address at compile time in BIN is not corresponding to the address being written.
