Thanks,

Finally I am able download the firmware to SD card and then successfully load the modem firmware.

Thank you for your help.

That's great to hear!

Have a nice day.

Hi Didrik,

Thanks,

Finally I am able download the firmware to SD card and then successfully load the modem firmware.

Thank you for your help.
I think due to low NB-IoT rate/poor coverage its take almost more hen 90min to downloaded the firmware.

Hi Thanks.

I resolved that error .error is related to file opening.

if I use your library it look very tricky to change that for SD. so now file system library to write on SD. once I able to successfully download the whole firmware image and then I try to read .bin file from SD card and upload to modem(might be I need some hint to do from you in this case).

What error do you get when trying to open the file?

I don't think we have tried using an SD card as external storage for full modem updates before. However, I cannot think of any reasons why it wouldn't work. But, if you try to use our existing libraries for full modem updates, you might have to make some modifications for it to work with an SD card instead of an external flash chip.

Hi,
sorry for late reply.

I used disk access for SD card mount https://docs.zephyrproject.org/3.0.0/reference/storage/disk/access.html and file system for read and write operation on sd card.

actually i want to directly write the download data in to .bin in sd card .if i follow this way is it work?

after downloaded 1kb data the fs failed to open file. I had attached the downloaded .bin file

Have you looked at how full modem update is implemented in the http_update/full_modem_update sample?

You need to call dfu_target_full_modem_cfg() before starting the download, so the dfu_target library knows where to store the new modem image.

If you look at the warnings (which should be treated as errors, unless you know what they mean, and are okay with the error. One example where Kconfig warnings might be okay is if it complains about log related options, but you have disabled serial knowing that you will not get any log), you will see that CONFIG_DFU_TARGET_FULL_MODEM couldn't be enabled because CONFIG_FMFU_FDEV is disabled.

The other warning gives the reason why CONFIG_FMFU_FDEV is disabled: CONFIG_CDDL_GEN and MBEDTLS_SHAR256_C are not enabled, and CONFIG_NRF_MODEM_LIB_SYS_INIT is enabled.

I recommend you look at the prj.conf file in the http_update/full_modem_update sample to see how these options are set (e.g. CONFIG_MBEDTLS_SHA256_C also has some requirements that must be met before it can be set. These should be clear from looking at the prj.conf).

You should also note that when disabling CONFIG_NRF_MODEM_LIB_SYS_INIT, you must initialize this library yourself in the application, before you can use the modem. Disabling CONFIG_NRF_MODEM_LIB_SYS_INIT might also mean that other libraries that depends on modem_lib no longer get initialised automatically.

Also, I see you still have bsdlib related configurations in your code. That library was replaced/changed name to nrf_modem_lib.

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.

warning: FMFU_FDEV (defined at C:/v1.5.0/nrf\subsys\dfu\fmfu_fdev/Kconfig:7) was assigned the value
'y' but got the value 'n'. Check these unsatisfied dependencies: CDDL_GEN (=n),
(!NRF_MODEM_LIB_SYS_INIT) (=n), MBEDTLS_SHA256_C (=n). See

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?

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;
}

Hi Didrik,

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

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

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
