I want to store some calibration and configuration data in lpc2148 flash memory. Also this data must be loaded into ram at startup. When data is changed i will write it into the flash(using IAP).

Below table show flash sectors for LPC2148. For EEPROM emulation i will use sector-26
enter image description here
Also when using IAP, top 32 bytes of RAM must be reserved.

This is as far i have modified the scatter file(keil uvision 4), is it ok? Also how do i load eeprom data into ram?

LR_IROM1 0x00000000 0x0007BFFF  {    ; load region size_region
  ER_IROM1 0x00000000 0x0007BFFF  {  ; load address = execution address
    *.o (RESET, +First)
    .ANY (+RO)

  ER_IROM2 0x0007C000 0x00001000  {  ; load address = execution address


  RW_IRAM1 0x40000000 0x00007FE0  {  ; RW data
    .ANY (+RW +ZI)
