RT1050: Enable HAB signed boot via SWD interface

I've tried to enable and flash signed image using the MCUBootUtility software via the USB HID interface.

For the speed of the mass-production in factory, we would like to still use the SWD interface for programming..

From my brief understanding, to enable the HAB signature, the signed bootable image need to be programmed and the SRK0~7 in eFuse need to be programmed .

To programed a signed bootable image should be feasible with the SWD interface I guess.

So if it is possible to program the SRK0~7 in eFuse using the SWD interface?

Thanks

-- No, I'm afraid it's impossible.
