## Internal Bootloader: Image Size, Selecting Storage Slot Address and Size

The internal storage bootloader for Matter OTA Software Update is supported on MG24/MG26 boards. In this use case, both the running image and the downloadable update image must fit on the internal flash at the same time. This in turn requires that both images are built with a reduced feature set such as disabled logging and Matter shell (see [here](./02-ota-software-update.md#Internal-Storage-Bootloader) for the list of features). Using LZMA compression when building the GBL file further reduces the downloaded image size.

Using LZMA compression when building the GBL file further reduces the downloaded image size.

When building an internal storage bootloader, the two key configuration parameters are the **Slot Start Address** and **Slot Size** in the **Bootloader Storage Slot** component. The storage slot must not overlap with the running image and the NVM section of the flash. In other words, the slot start address must be greater than the end of the running image address and the sum of the start address and the slot size must be less than the address of the NVM section.

Installing the Lower Power Mode component in the project's Software Components tool in Simplicity Studio will uninstall the following optional components and reduce the image size:
