nRF54L15 with MCUBoot

jeos 8 months ago

Hi,

I've got an nRF54L15-DK, and I'm trying to get the sysbuild with mcuboot example working. https://docs.zephyrproject.org/latest/samples/sysbuild/with_mcuboot/README.html

I can successfully get my board to work if I set SB_CONFIG_BOOTLOADER_MCUBOOT=n, but if I set it to 'y', my board no longer works.

If I target 'nrf54l15dk/nrf54l15/cpuapp' my app works, but it doesn't work if I target 'nrf54l15dk/nrf54l15/cpuapp/ns'. However if I target 'cpuapp' only, VSCode has a warning of 'You are going to build without security by separation and Trusted Firmware-M (TF-M). Consider selecting the nrf54l15dk/nrf54l15/cpuapp/ns board target to better protect sensitive assets and code. In the /ns version of the board target, TF-M is automatically built as the secure firmware image.'

Is this the intended behaviour?

Using NCS 3.1.0. nRF54L15-DK 0.9.2 2024.49.
