I want to do firmware updates over BLE. To do that I added these settings to my prj.conf which I mostly got from the smp_svr example:
This "works" but it uses the default signing key. So I added CONFIG_MCUBOOT_SIGNATURE_KEY_FILE="signing_key.pem" according to this answer but I got this message during build:
If I follow that advice and set CONFIG_BOOT_SIGNATURE_KEY_FILE I get these messages:
But it doesn't seem like MCUBOOT_BUILD_STRATEGY_FROM_SOURCE is a valid prj.conf setting for an NCS project?
I'm on NCS 1.9.1.
