Softdevice ID for NO softdevice

[W9]

What is the ID for indicating that NO SD is required in a DFU pkg?

I am using SDK15 with a secure UART bootloader, but NO soft device. (just MBR, APP, BL & BL settings)

When I use "nrfutil pkg generate --application  app.hex --hw-version 52 --key-file MY_specialkey.pem app_pkg.zip" , nrfutil complains that I need a Soft device ID.

Is there an up-to-date list of valid Soft device IDs?

Also, why do I need to enter a "--hw-version" in this pkg?

I am using nrfutil v3.5.1

Thanks for your help.

After more searching, I found my answer to this question. In SDK 15, DFU Bootloader examples, Secure DFU Bootloader over Serial Link, in the Acceptance  rules for Versions, bullet SoftDevice Firmware ID; Follow the link to 'Updates without a SoftDevice;' a value of 0x00 implies no SD is required.
