Bootloader progress

[Stefano1984]

Hello everyone,
I'm using the secure_bootloader example to load the application into my device.
I need to detect bootloader progress, can anyone tell me how? I would like to see a progress bar on a display to show the firmware charge status.
Thank you.

Hi, 

Check out my colleague's sample https://github.com/hellesvik-nordic/samples_for_nrf_connect_sdk/tree/main/bootloader_samples/updatable_bootloader/nsib_simple 

It will show the log as

*** Booting Zephyr OS build v3.2.99-ncs1 ***
Attempting to boot slot 0.
Attempting to boot from address 0x9000.
Verifying signature against key 0.
Hash: 0x2c...8a
Firmware signature verified.
Firmware version 2
Setting monotonic counter (version: 2, slot: 0)
*** Booting Zephyr OS build v3.2.99-ncs1 ***
Change this to see change.
Firmware version 2

Regards,
Amanda H.

Hi,

Sorry, but I did not understand. I want to see the percentage of firmware loaded in real time. Can you give me a code example? Thank you.

Do you mean the upload/transmit percentage? If so, mcumgr can provide the transmit percentage of firmware as
 

If you mean the update status of the bootloader, there is only the log reflecting the status instead of the percentage.
