https://devzone.nordicsemi.com/f/nordic-q-a/2281/program-download-methodsHI,all! I have a question about downloading program into nrf51822 MCU. That is: As you konw, using the nRFgoStdio to download the code, you have to download the softdevice hex first and then download the application hex laterly, but I want to combineen-USTelligent Community 13Fri, 25 Apr 2014 06:08:37 GMThttps://devzone.nordicsemi.com/thread/9518?ContentTypeID=1Fri, 25 Apr 2014 06:08:37 GMT137ad170-7792-4731-bb38-c0d22fbe4515:c66e281c-1700-497c-90ee-fd2ce1e0edcekk<p>thank you very much, i got it and managed to make it out!</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/9517?ContentTypeID=1Tue, 22 Apr 2014 12:18:16 GMT137ad170-7792-4731-bb38-c0d22fbe4515:70fb32b5-e778-499a-bb07-66d77c8a599eJohn<p>The post Kristin linked pretty much addresses the question. I just wanted to add one bit of specificity to it: I added the following post build command to my project to merge my application with the softdevice:</p> <p>C:\Program Files (x86)\Nordic Semiconductor\nrf51\bin\mergehex -m ._build\onset_mx1101.hex .\s110_nrf51822_6.0.0_softdevice.hex -o ._build\mx1101_merged.hex</p> <p>Later when I build my bootloader project, it merges my &quot;mx1101_merged.hex with the bootloader to produce the file that is programmed in production.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/9516?ContentTypeID=1Tue, 22 Apr 2014 10:50:20 GMT137ad170-7792-4731-bb38-c0d22fbe4515:9466bc7d-fe25-411f-bcce-9897174116f2FormerMember<p>Hello,</p> <p>Please take a look at <a href="https://devzone.nordicsemi.com/index.php/nrf51822-how-to-merge-software-device-and-application-code-to-one-hex-file">this</a> post and see if it answers your question.</p> <p>Regards, Kristin</p><div style="clear:both;"></div>
