Thanks for the update Yes, the pm-ext-flash property must be set as well (External flash memory partitions)

maybe this was missing in the overlay:

/ {

chosen {

nordic,pm-ext-flash = &mx25r64;

};

};

after add:

Hi Vidar,

now the pm_static.yml:

### EXTERNAL FLASH PARTITION TABLE ###

external_flash:

fota_header: # Padding di 32kB con informazioni sulla versione

are all right for you ?
I don't see external flash section

Thx's always,

Hello Babos,

Please check the generated pm_config.h header in your build folder to find the symbols generated for your pm static file (build/zephyr/include/generated). Also, the external_flash flash region does not specify which Q/SPI flash device you are using which is required, see https://github.com/nrfconnect/sdk-connectedhomeip/blob/e6a1e8e9a010c641c9998e197e65bea15cce8c11/examples/all-clusters-app/nrfconnect/configuration/nrf7002dk_nrf5340_cpuapp/pm_static_dfu.yml#L51

Best regards,

Vidar
