BLE DFU for matter device

[Jacob Lee]

Hi,

I tested the (mcu_boot + smp_svr) example and can run dfu successfully with nrf_connect application.
(Follow the page: developer.nordicsemi.com/.../README.html)

Now I am trying to merge the configurations to matter lock-example project on 52840DK.
I check the default partition layout listed in nrf52840dk_nrf52840 dts:
mcuboot       48K
image-0       412K
image-1       412K
image-scratch 120K
storage        32K

The matter stack can't fit in image-0 partition.
So what's your suggestion about the DFU over the air on 52840 for matter device?


thanks,
Jacob

Hi Jacob,

I recommend you use the DFU configuration already included in the Doorlock and Lightbulb sample as a starting point (link). These place the secondary slot in the external QSPI flash to get around this size restriction.

Best regards,
