* :example:`custom_bootloader/bootloader_override` presents how to override the bootloader implementation
In the bootloader space, you cannot use the drivers and functions from other components. If necessary, then the required functionality should be placed in the project's `bootloader_components` directory (note that this will increase its size).
In the bootloader space, you cannot use the drivers and functions from other components unless they explicitly support run in bootloader. If necessary, then the required functionality should be placed in the project's `bootloader_components` directory (note that this will increase its size). Examples of components that can be used in the bootloader are:
* :example:`storage/nvs_bootloader`
If the bootloader grows too large then it can collide with the partition table, which is flashed at offset 0x8000 by default. Increase the :ref:`partition table offset <CONFIG_PARTITION_TABLE_OFFSET>` value to place the partition table later in the flash. This increases the space available for the bootloader.
