Hi,

Yes, that is correct, it's now in the MBR. It was done because the UICR can't be protected from write. It should be backwards compatible as long as the value on adress 0xFFC is 0xFFFFFFFF.

Thanks for the link to the definition how the MBR handles the parameter page.

I guess what confuses me is the following line in the SDK 15.3:

#define NRF_UICR_BOOTLOADER_START_ADDRESS (MBR_BOOTLOADER_ADDR)

With this define the UICR address is on address 0xFFC in the MBR? In the last SDK version this was an address in the UICR.

Regards Adrian

Hi,

This is specified in the Softdevice specification here.
