Application won't boot when bootloader and app are using 32kHz RC oscillator. When using MPSL (BLE and IEEE802.15.4 raw) or usb_cdc.

Hi Hung Bui,

I've tested and verified that your 4075merged.hex is working on my devkit. I've also tested it on a second devkit which also works.

I've tried to reproduce the binary but my sha256 hash won't match your binary. I'm using the following setups:

Mac: 

arm-toolchain-9-2020-q2-update

NCS-1.8.0

cmake version 3.21.4

West version: v0.11.0

Linux Ubuntu 20.04:

Zephyr SDK 0.13.1

NCS-1.8.0

cmake version 3.22.0

West version: v0.10.1

What setup are you using and could you try to reproduce ours? 

Lastly could you specify which command you used to produce the hex file you provided? 

Thanks!

Best regards,

Maarten

Hi Maarten, 

I used what suggested in the howtoreproduce.md file you provided: 

west build -p -b nrf52840dk_nrf52840 -- -DDTC_OVERLAY_FILE=console.overlay && west flash

My set up was with NCS v1.8.0 and Zephyr v2.7.0-nc1 , mcuboot v1.7.99-ncs4

I assume you are using https://github.com/zephyrproject-rtos/sdk-ng ? 

Have you tried to install the toolchain using our nRF Connect Toolchain manager ? 

I might not be able to reproduce the exact setup you have. You may want to try our downstream Zephyr : https://github.com/nrfconnect/sdk-zephyr

Also it should be possible to debug MCUBoot to check which issue caused the crash.
