Hi,  I am evaluating the MCUBOOT example, and need your help to provide the script to sign the OTA image.

MCUXpresso IDE v11.10.0

MIMXRT1180-EVK board (SCH-50577 REV C3)

SDK v2.16.000

I import "evkmimxrt1180_mcuboot_opensource_cm33" and "evkmimxrt1180_ota_mcuboot_server_enet_cm33" using default settings.

I tried several time refer to the readme.md, but failed to load OTA image.

To sign the OTA image in your MCUBOOT project, locate the sign_script.py in the MCUBOOT tools directory. This script is used to generate the signed image. Follow the detailed steps in the readme.md file to ensure proper usage. If issues persist, verify the settings in your project to match those required by the script and MCUBOOT configuration.

Thanks. But I can not find sign_script.py.

Solved by local FAE.

Which *.pem file does the "evkmimxrt1180_mcuboot_opensource_cm33" used?

Which *.pem file should the imgtool.py use?

Below is my script. I copied "mcuboot_opensource" from SDK to "workspace\evkmimxrt1180_ota_mcuboot_server_enet_cm33\scripts"

python imgtool.py sign --key ../enc-rsa2048-priv.pem --align 4 --header-size 0x400 --pad-header --slot-size 0x200000 --version "2.0" ..\..\..\Release/evkmimxrt1180_ota_mcuboot_server_enet_cm33.bin ..\..\..\Release/evkmimxrt1180_ota_mcuboot_server_enet_cm33_SIGNED.bin

signed successfully.

Write it to board with start address 0x28040000.

But MCUBOOT reports "Unable to find bootable image".
