Unable to find bootable image using the direct-xip with revert boot mode.

[taspon98]

I am facing a similar issue described in  https://devzone.nordicsemi.com/f/nordic-q-a/97084/direct-xip-mcuboot-both-images-have-the-same-version  where mcuboot is unable to find any bootable image after flashing the device using the direct-xip with revert boot mode. However, this issue does not exist if I use direct-xip without revert and everything works as intended when doing DFU. Therefore, I am wondering if there are any KConfig changes or extra settings that I will need to make to enable support for direct-xip with revert (I am using NCS 2.7.0). Thanks for the help in advance!

Hi, 

Could you build the image with -DCONFIG_MCUBOOT_EXTRA_IMGTOOL_ARGS=\"--confirm\"? 

Please let me know if this can help or not. Thanks.

Thank you this works! I am trying to figure out how to revert back to the previous image using either the NRF device manager app or the newtmgr. According to https://docs.mcuboot.com/design.html#direct-xip-revert, the image will need to get "selected (setting the copy_done flag)" before performing the revert. However, I don't see any option to that on both approaches, and sending the "confirm" command doesn't seem to do anything as it doesn't set the confirm flag in the image with the older version in slot 0. Do you happen to have any insight to how the revert mechanism should be utilize in xip-revert? Thanks!

Actually, it looks like downgrade is not supported. Such a shame
