I downloaded the nRF Connect SDK v2.7.0 and read the Release Notes. I installed the v2024.7.18 (pre-release) version of the nRF Connect for VS Code. As a first step, I created an application by copying the Matter Template sample to my local work directory, using the command:
NRF CONNECT -> WELCOME -> Create a new application -> Copy a sample -> Matter Template
I opened an nRF Connect terminal and ran this command:
west build -b nrf52840dk/nrf52840
I got this error:

Recognizing that the MCUBOOT was larger than the mcuboot partition that is defined in the pm_static_nrf52840dk_nrf52840.yml file (included in the sample code), I looked at other pm_static.yml files in the sample code main directory and saw that the pm_static_nrf5340dk_nrf5340_cpuapp.yml file had a larger partition for mcuboot. So, I tried this experiment. I did the following:
1. cp pm_static_nrf5340dk_nrf5340_cpuapp.yml pm_static_nrf52840dk_nrf52840.yml
2. west build -b nrf52840dk/nrf52840
3. west flash
After flashing this code to my nrf52840 DK board, I get this error when the board boots:
*** Booting MCUboot v2.1.0-dev-daf2946a0f07 ***
*** Using nRF Connect SDK v2.7.0-5cb85570ca43 ***
*** Using Zephyr OS v3.6.99-100befc70c74 ***
I: Starting bootloader
E: Failed to open flash area ID 1 (image 0 slot 1): -2, cannot continue
What can I do to get this sample to build and run on my DK board?
Thanks,
