I am getting error as

Please let me know that have I added wrong bootloader file to segger bcause of which MCU is not working or please share steps how to configure segger for MCU

Master Control Panel will only work with a device flashed with the Master Emulator Firmware(MEFW). Use nRFGo Studio to erase the nRF51 Dongle, then go to Master Control Panel, select File --> Flash Programming. Make sure MEFW nRF51822 0.11.0 is selected and then press Program.
