Hi,
I follow the execise https://academy.nordicsemi.com/courses/nrf-connect-sdk-intermediate/lessons/lesson-8-bootloaders-and-dfu-fota/topic/device-firmware-update-dfu-essentials/ to add MCUboot. The following is my step
1. copy sample mqtt
2. build configuration using nrf7002dk_nrf5340_cpuapp_ns.conf
3. add CONFIG_BOOTLOADER_MCUBOOT=y in prj.conf
4. create a child_image and create a file mcuboot.conf
5. add one line CONFIG_MULTITHREADING=y to mcuboot.conf
6. Modify nrf7002dk_nrf5340_cpuapp_ns.conf and set CONFIG_PM_PARTITION_SIZE_TFM=0x43E00
I have no any idea why this error happened. Any idea?
Lance
