Over the Air modem(AWS MQTT) Firmware update 1.2.3 to 1.3.1

[Waqar Ahmed]

Hi,
I want to update the modem firmware devices(in the field).I am using nRfconnect sdk 1.5.0 and hardware is brf9160 SICA B1 .
current modem firmware is 1.2.3 .
I tried to https://devzone.nordicsemi.com/f/nordic-q-a/81643/full-modem-firmware-update-for-modem-v1-3-0/357363#357363.

but I am unable to update.
I am using AWS (MQTT) for FOTA updates.

CONFIG_DFU_TARGET=y
CONFIG_DFU_TARGET_FULL_MODEM=y

but its not enabling the DFU_TARGET_FULL _MODEM.

build_path\zephyr\.config

DFU configuration

#
# DFU
#
CONFIG_DFU_TARGET=y
CONFIG_DFU_TARGET_MCUBOOT=y
CONFIG_DFU_TARGET_STREAM=y
# CONFIG_DFU_TARGET_MCUBOOT_SAVE_PROGRESS is not set
CONFIG_DFU_TARGET_MODEM_DELTA=y
CONFIG_DFU_TARGET_MODEM_TIMEOUT=60
# CONFIG_DFU_TARGET_LOG_LEVEL_OFF is not set
# CONFIG_DFU_TARGET_LOG_LEVEL_ERR is not set
# CONFIG_DFU_TARGET_LOG_LEVEL_WRN is not set
CONFIG_DFU_TARGET_LOG_LEVEL_INF=y
# CONFIG_DFU_TARGET_LOG_LEVEL_DBG is not set
CONFIG_DFU_TARGET_LOG_LEVEL=3
# end of DFU
# end of DFU

Please guide me about the necessary configuration.
Thanks

Hi,

First of all, does your custom board have external flash that can be used to store the new modem FW while downloading?

Do you get set CONFIG_FMFU_FDEV=y and CONFIG_STREAM_FLASH=y?

Best regards,

Didrik

Hi Didrik,

not set the configuration before.i will set it now.

Yes with my custom board i have 16GB SD card.

Thanks

[Waqar Ahmed]

still the same problem.

still disable

#ifdef CONFIG_DFU_TARGET_FULL_MODEM
if (dfu_target_full_modem_identify(buf)) {
return DFU_TARGET_IMAGE_TYPE_FULL_MODEM;
}
#endif
LOG_ERR("No supported image type found");
return -ENOTSUP;
}

Do you get any Kconfig warnings when building?

Which IDE are you using?

How do you set the config options?

Can you share your prj.conf?

[Waqar Ahmed]

Hi Didirik,
Please find the attached .config file

Yes, i am getting these two warnings

warning: DFU_TARGET_FULL_MODEM (defined at C:/v1.5.0/nrf\subsys\dfu\dfu_target/Kconfig:74) was
assigned the value 'y' but got the value 'n'. Check these unsatisfied dependencies: FMFU_FDEV (=n).
See docs.zephyrproject.org/.../CONFIG_DFU_TARGET_FULL_MODEM.html and/or
look up DFU_TARGET_FULL_MODEM in the menuconfig/guiconfig interface. The Application Development
Primer, Setting Configuration Values, and Kconfig - Tips and Best Practices sections of the manual
might be helpful too.
