What should the value of '-sd -req' be to fit s132_nrf52_7.2.0_softdevice.

Hi Luo, 
You can find the Firmware ID for the softdevice in the softdevice release note. This file located inside nRF5_SDK_17.0.2_d674dde\components\softdevice\s132\doc
For S132 v7.2.0 it's 0x0101

As already stated in https://github.com/NordicSemiconductor/pc-nrfutil/issues/342 nrfutil should really be updated. See also https://devzone.nordicsemi.com/f/nordic-q-a/69907/bootloader-dfu-buttonless/286737

I ran into a similar issue with S112 + nRF5_SDK version 17.2 and SD version 7.2.

Wish the nrfutil would add these new values to the output of its '--help' command.
