External Flash (SPI) - MCUBoot - OTA

[MehdiChelouah]

I have been able to set up external flash for MCUBoot for FOTA.

But after rebooting, the image is the same than before the image upgrade.

I used a sniffer so i could see SPI transmission with external flash during the process but all i can see is writing the new image to the flash, not reading it when swapping.

That's how my partitions are built

And here is my mcuboot.conf in child_image folder

I just sent you the files with private message

Hi,

 

You sent parts of the board dts, but not the overall build DT that I requested.

 

In your build-folder, ie:

my_project/build-folder/zephyr/zephyr.dts

my_project/build-folder/mcuboot/zephyr/zephyr.dts

 

These two files will hold the full device tree configured for each project.

 

Can you please post all your changes to the lwm2m_firmware file?

It is important that the update is marked as done (if successful), and that the update is scheduled, as shown in these two calls:

https://github.com/nrfconnect/sdk-nrf/blob/v2.0.0/subsys/net/lib/fota_download/src/fota_download.c#L204-L206

 

Kind regards,

Håkon
