Hi,
I'm trying to FOTA over BLE firmware of mcuboot using NRF52840DK.
The project is based on the sample from Intermediate course - Lesson 8, exercise 3 (without the steps relevant to nrf53 - steps 6 to 9).
also, the project uses the NSIB, and the external flash to host the mcuboot_secondary partition.
My main goal is to be able use the dfu_mcuboot.zip file in order to not mess with the management of which slot and which bin file to flash.
With that said, I tried follow some guidelines from this ticket, where someone replied: "What I found out is that the dfu_mcuboot.zip currently doesn't work with the Device Manager App."
this ticket is old, and I hope that till then things changed, but unfortunately I still can't use the zip file. (I did use the bin files and it works well, but that is not what I need).
First question: Regarding the above ticket's answer, is there another application besides Device Manager App that can handle the zip files?
Back to my project and my attempts:
I checked the manifest.json file (inside dfu_mcuboot.zip) on both "versions" (using the CONFIG_MCUBOOT_IMGTOOL_SIGN_VERSION, and by modifying BOOT_LOG_INF inside /ncs/v2.6.1/bootloader/mcuboot/boot/zephyr/main.c - to be able to see the change between versions)
the results was:
- First build -

which makes me wonder if there is a problem/missing argument when building the project - all the attempts ended with manifest that is not aware of the old version.
Note that I tried multiple build ways:
1. new build configuration -> Pristine build for version 0.1.5+5, Pristine build for version 0.1.6+6
2. new build configuration -> Pristine build for version 0.1.5+5, normal build for version 0.1.6+6
Also, I tried to increment the CONFIG_FW_INFO_FIRMWARE_VERSION in mcuboot.conf, using the same build attempts as above.
All the attempts yield the same manifest behavior, and on the Device Manager App I got the next error when trying to FOTA - Hash not found (8)
