Hi,
I need to add to my project that uses NRF5340 a bootloader that reads new firmware from SDCard. Is there an example where I can find information? Someone has just encountered this kind of issue and can tell me some tips?
Thanks
Marco

Hi Vidar,
Sorry again, but there is something strange: after a firmware update correct (only with your method, not by SD), the microcontroller start with a string that print the new version value... but after a reset a new firmware update was performed without my command and turn back to the first version. What is it wrong? The log is the following.

By SD no magic word was set!

Hi Marco,
After the image was copied from the SD card to the secondary slot, did you run boot_set_pending()? This marks the image as a pending update, which includes writing of the magic word.
warcomeb-am said:but after a reset a new firmware update was performed without my command and turn back to the first version.
MCUBoot will revert the update if the image is not confirmed as the hex file contains a "test" image. You can read more about the different swap types here: https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/mcuboot/design.html#boot-swap-types.
To make a "test" image permanent, you can call boot_set_confirmed() from the new app.

Vidar
Hi Vidar,
good news: thanks to your help, now the firmware is updated. I added boot_set_pending() after the copy of the new firmware into image_1 from the SD and at the reboot the new firmware is active. But I have some doubts. The log is the following:

I read the documentation that you suggest to me, but I don't understand the change of word and status during the three reboots.
Anyway, I don't add boot_set_confirmed() and the swap it is not happen.
I am a little bit confused.

Hi Marco,
I am glad to hear that it worked. I forgot to mention the boot_set_pending() function when asked earlier about the DFU steps. Anyway, the swap is set to "perm" for permanent, not "test" like earlier. This means the image is already confirmed so there is no need to call boot_set_confirmed() to avoid rollback.

Hi Vidar Berg ,
after some months I came back to you. The update works, but the compiler told me that can't find boot_set_pending() function [implicit declaration]. Witch file I can include to avoid this warning?
