Signing update rejected

[Fabien Comte]

When i try to do an update with Nrfutils Under android i get a REMOTE_DFU_OPERATION_FAILED since i added signing.

I created my pem file key with nrfutil.exe keys i copied Qx and Qy in my dfu_init_template_signing.c i modified Makefile to use dfu_init_template_signing.c instead of dfu_init_template.c i signed my update with my pem file key

Hi Fabien,

I have attached a modified version of the nRF5 SDK v11.0.0, where I have ported the DFU with signing example from nRF52 SDK v0.9.2.

facotl(Fabien Comte): Why aren't you using the linker settings in the dfu_gcc_nrf52.ld linker script?
