Bootloader customized to decompress LZ4 DFU firmware image

Markus Arnoldsson

Hello! 

I am working on a FOTA solution for the nRF52DK, I have followed this example: https://devzone.nordicsemi.com/guides/nrf-connect-sdk-guides/b/software/posts/ncs-dfu

The FOTA works using the nRF Device Manager application and a binary image file.

For the project, it is planned to compress the binary image file with lz4 and in the bootloader of the MCU include a decompressor.

I am now wondering how the MCUBoot can be customized in order to decompress the firmware file coming in (LZ4 compressed)?
