Hi, Sir:
I am using nRF9160 for development, I would like to complete a COAP client,so I need to refer to ......./nrf/samples/nrf9160/coap_client. I installed NRF_Connect_SDK refer to the url: https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/gs_ins_linux.html
and I checked out the master branch to use the latest state of development.
I have a nRF9160 DK,and I use emStudio to develope.
According to user guide，I did the following :
(1) program the ....../nrf/samples/nrf9160/spm to nRF9160 DK,then, open Serial Port Tool.Reset the nRF9160 DK.I saw the following log:

(2) program the ....../nrf/samples/nrf9160/coap_client to nRF9160 DK.Reset the nRF9160 DK.The log is:

[14:01:54:040] Fatal fault in essential thread! Spinning...␍
I checked the ....../nrf/samples/nrf9160/coap_client programming information
Programming 15.4 KB of addresses 00000000 – 00003dbb
Programming 0.5 KB of addresses 00017eb8 – 000180d7
J-Link: Flash download: Bank 0 @ 0x00000000: Skipped. Contents already match
Obviously this programming address overlaps with SPM.
I guess reasons for this fault is wrong FLASH_BASE_ADDRESS or FLASH_LOAD_OFFSET ,so
I tried to modify FLASH_BASE_ADDRESS or FLASH_LOAD_OFFSET to 0x40000, But still didn’t work, how to modify configure of the example to work well?
Best wishes
