Hi,

custom board not have 32.768khz crystal

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
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

debug doesn't start
1. 
2.

My deepest apologies, it should be "child_image" not "child-image".
Kind regards,
Håkon
ok, No issue i'll try it. Thank you
