Hi,

The start address of the Softdevice is actually 0x1000 as you can see here: Memory resource map and usage. The MBR is included in the Softdevice hex files.

Hi,

OK,because I want to perform thread secure DFU for ble_thread multiprotocol programs, but thread secure DFU does not use softdevices, but MBR. Because the flash start address of MBR is 0x0 and the size is 4KB, I want to modify the flash start address of softdevice to 0x01000

Hi,

Unfortunately, it's not possible change the start address as the Softdevice is being distributed by us as a pre-linked binary. Could you maybe provide some background for this requirement?
