what information does the nrfjprog.exe write to UICR(User Information Configuration Registers) register??

==========Tutorial of Flashing dfu bootloader to the nRF51 DK====== we need to make sure that nrfjprog.exe is configured as the tool for flash programming in project options. The default J-link target driver cannot correctly program the bootloader, this is because J-link can not write directly to the User Information Configuration Registers(UICR) from a hex file. The example project is preconfigured to use nrfjprog.exe, which is installed with the nRF51 MDK, and must be in the Windows system path.

there is an older project of sdk 6.0 in our projects, i check the hex of softdevice and boot.. and i found that the hex of softdevice include the address of bootloader(0X0003C800) .. but this hex of softdevice is different from the softdevice downloaded of sdk6.0. i have some doubt about it. maybe it is modified by manual.

the detail hex of older project:

:020000040000FA :10000000481C0020992B0100F1160100CF2A0100A5 :1000100000000000000000000000000000000000E0 :100020000000000000000000000000000D2C010096 :100030000000000000000000F1160100F1160100B0 : ... ....

:020000041000EA :1010000000400100FFFFFFFFFFFFFFFFFFFFFFFFAB :081010004900FFFF00C80300C6 :04000005000000C136 :00000001FF

the line of 081010 00 4900FFFF 00C80300 C6, we know the address: 0x1014: 00c80300,

this address is the bootloader address of 0x0003 c800,

the hex file of bootloader:

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

the boot and softdevice are attached.

boot hex: Boot.hex

softdevice hex: s110_nrf51822_6.0.0_softdevice(1).hex

and i compare hex of softdevice. left side: hex of softdevice 6.0 in our old project. right side : original hex of softdevice 6.0

thanks, the first,i make sure hex of softdevice does not include bootloader address.
