Hi all,
by default, the "nRF5340: SMP Server with external XIP" sample does not support reverting images in case DFU was not successful. In other words, it does not swap slots, it just copies the new image over the old one. This is caused by the config CONFIG_BOOT_UPGRADE_ONLY being set to "y".
I had no luck building the sample with CONFIG_BOOT_UPGRADE_ONLY=n. I had a look into C:\ncs\v2.6.1\nrf\modules\mcuboot\nrf5340_exip_image.conf and I can see that this config is set to "y" there. Also there is a note stating that this config is needed to make simultaneous multi image update possible. Does this mean that the only way to achieve multi image DFU for nrf5340 with part of code in QSPI flash is to have this config set to y? Or to make the question more generic - is there a way to have the posibility of reverting images after update in this multi image + QSPI XIP scenario?
Thanks!
