I have like to boot the board with MK20DX256VLH7. ( we will  make the board )

( MK20 : internal flash size 256KB, internal eeprom size 2KB )

We are going to use the bootloader (NXP_Kinetis_Bootloader_2_0_0) and application (SDK_2.0_MK20DX256xxx10).

My qeustion is, is it possible to do the following sequence ?

  1. Compile the bootloader.
  2. Write the bin file to the internal EEPROM. (0x00)
  3. Compile the Application.
  4. Write the bin file to the internal Flash. (0x00)
  5. Power on the MK20 board.
  6. Jump to the internal flash after running the bootloader from Internal EEPROM.
  7. Excution the Application from Internal Flash.

If this sequence is possible, can I load the bootloader into the EEPROM with JTAG ?
