Well, that is because it was a little lesson.
Don't be lazy and do it yourself. It is _not_ rocket science. Read the user manual of the chip. Check out some CRC argorithms. Understand the structure of your vector table.

I have some idea about the Boot Code which will be stored in the Bank 1 location from the starting address 0x0000.0000 and end adress 0x0000.7FFF. I have few questions how to find on which adress location the CRC of Bootcode will be stored.

"I have few questions how to find on which adress location the CRC of Bootcode will be stored."

If you have a few questions, why don't you ask them instead of requesting code ASAP?

For the boot code i need the address location for storing the CRC value and length of the CRC.

i.e. on which address location from 0x0000.0000 to 0x0000.7FFFF boot CRC value and length will be stored.
