Resumption of copying Secondary slot image into primary slot image with MCUBOOT_OVERWRITE_ONLY

[Ubaid_M]

Hi,

1. Please point me to a sample DFU project which works overwrite method..?

2. When MCUBOOT_OVERWRITE_ONLY is enabled, and during copying of image, if there is power loss, upon power back on, does the copying resume..?

Thanks,

Ubaid

We do not have an example to demonstrate this yet.

The continuation of the DFU from the last known state will still be functional as far as I see even with the MCUBOOT_OVERWRITE_ONLY

No issues with working on 'MCUBOOT_OVERWRITE_ONLY" mcuboot configuration right..?

Looking at the implementation and the patches done here, yes it should work with MCUBOOT_OVERWRITE_ONLY with slot0 only as there will be no copying involved from slot1 to slot0 here.

No project yet as a reference for me to get started..?

Unfortunately, There is no reference project that I can see for this yet.
