https://devzone.nordicsemi.com/f/nordic-q-a/17086/how-to-burn-bootloader-and-flash-program-to-a-nrf52-pcbHi, I am developing a printed circuit board for myself using a NRF52 and I am unsure how to actually burn a bootloader program to the NRF52. Additionally, once the bootloader is burned, how does one flash a program. How does this work with S132 softdeviceen-USTelligent Community 13Mon, 17 Oct 2016 09:09:59 GMThttps://devzone.nordicsemi.com/thread/65514?ContentTypeID=1Mon, 17 Oct 2016 09:09:59 GMT137ad170-7792-4731-bb38-c0d22fbe4515:ef2c0e04-9f79-45dd-b755-9e2e88681d1dJ&#248;rgen Holmefjord<p>Hi,</p> <p>You can find information about <a href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.gs/dita/gs/prod_test_prog.html?cp=1_6">Production programming and testing</a> in the nRF5 Getting Started chapter on the infocenter.</p> <p>If you have exposed the <a href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.nrf52832.ps.v1.1/dif.html?cp=2_2_0_15_0#dap">SWD interface</a> on your PCB, you can program the chip using an external SEGGER J-Link programmer/debugger and <a href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.tools/dita/tools/nrf5x_command_line_tools/nrf5x_nrfjprogexe.html?cp=5_0_3">nrfjprog</a>.
