Writing the Program in both Flash bank A and Flash bank B in LPC43S57

Hi,

I am using LPC43S57 controller.

The program size is 335K bytes. Flash bank A size is 512kB and around 200kB is used by the bootloader and remaining 312kB is not enough for the program.

There is Flash bank B with size of 512kB. But when I configure the scatter file to use the Flash bank B the program doesn't executes.

Below I have attached the scatter file configuration.

   ER_IROM2 0x1B010000 0x00040000  ; execution address and size    Flash Bank A
  {
	.ANY (+RO)
  }
}

If anyone has the solution or example code to use both the Flash bank A and B, Kindly share it with me.
