Hello,
I had purchased 6 nRF52840 Preview Development Kit boards in 2017 for study and development.
This year, I want to re-use the PDKs for a new BLE-THREAD related PoC. I have downloaded latest SDK "nRF5_SDK_for_Thread_and_Zigbee_v4.1.0" and build a sample example from "ble_thread_dyn_template". The compilation with appropriate tool chain on Eclipse went well but after downloading the program, it was observed that the nRF52840 resets after 4 to 5 seconds.
Same problem is observed with prebuilt hex file.
HW: nRF52840-Preview-DK
SDK: nRF5_SDK_for_Thread_and_Zigbee_v4.1.0_32ce5f8
SD: s140_nrf52_7.0.1_softdevice.hex
JLink Log:

My question is - How to use nRF52 Preview DK with latest SDK?
