custom board not have 32.768khz crystal

 Have you tried setting the LFCLK source to RC?

Kind regards,

Håkon

As like nrf5 sdk

Is there secure dfu if so any example related on that

the attached zip.file is my example project . this same code works in nrf52840 DK, BC840DK. but not in custom board .

Where i need to change any board file or in prj.confg .

I need example code for

Open dfu and secure dfu for better experience .

[Håkon Alseth]

Could you try creating this file in:

your-project/child_image/mcuboot.conf

 

containing this configuration as well?

 

Kind regards,

Håkon

[Sunil vignesh]

I couldn't catch that

do you mean i need to create the folder child-image and bare mcuboot.conf file

what should be inside that .conf file

[Håkon Alseth]

This configuration shall be set in that child-image/mcuboot.conf file:

https://github.com/nrfconnect/sdk-zephyr/blob/master/drivers/clock_control/Kconfig.nrf#L33

 

Kind regards,

Håkon

[Sunil vignesh]

debug doesn't start

1.

2.

[Håkon Alseth]

My deepest apologies, it should be "child_image" not "child-image".

 

Kind regards,

Håkon

[Sunil vignesh]

I have confg

# Clock configuration
CONFIG_CLOCK_CONTROL_NRF_K32SRC_SYNTH=y

in prj.conf

and also in child_mage\mcuboot.conf

config_CLOCK_CONTROL_NRF_K32SRC_SYNTH=y

but when i check configure nrf connect

for menuconfig

but when i see mcuboot config

how to change it in .config file

[Sunil vignesh]

and when i change this in configure menu

i got this error

[Sunil vignesh]
