    Hi there,

    I have looked into what the possible causes for this could be, and the following was what was found:

    - MCUBoot performs full verification over the images at each boot, which takes a while. The execution time of MCUBoot on CC2340Rx is long for the following reasons:
       
        - CC2340R5 does not use an ECC hardware accelerator to verify keys to in order to ensure that the FW image is safe
        - MCUBoot image verification times may be affected by the images sizes

    To speed this up, you could try to disable debugging. Doing so might help speed things up slightly.
