I use the git bash command line run it, finaly use p256 work

My current configuration is as shown in the following figure.

However, in the previous configuration, I used a single definition and did not explicitly disable other signature methods. I suspect that other signatures were also enabled, causing the problem

SB_CONFIG_BOOT_SIGNATURE_TYPE_ECDSA_P256=y

Hello,

you can run "imgtool dumpinfo" on the signed *.bin file to check if it has a valid mcuboot header or not. But Are you signing the image yourself from the command line, or are you using the dfu_application.zip file from the build folder?

Best regards,

Vidar

Using v3.0.1, neither "Test and Confirm" nor "Confirm only" works
