.. title:: FLASH_LOAD_OFFSET

.. option:: CONFIG_FLASH_LOAD_OFFSET

*Kernel load offset*

Type: ``hex``

Help
====

This option specifies the byte offset from the beginning of flash that
the kernel should be loaded into. Changing this value from zero will
affect the Zephyr image's link, and will decrease the total amount of
flash available for use by application code.

If unsure, leave at the default value 0.
