https://devzone.nordicsemi.com/f/nordic-q-a/116856/about-nrfutil-protocolDear Devzone, I currently use the nrfutil dfu serial command to upgrade the firmware, which is OK. I want to upgrade the firmware of 52832 through MCU, so I need to know the protocol of nrfutil. Do you have relevant documents to provide?thanks!en-USTelligent Community 13Mon, 02 Dec 2024 11:03:58 GMThttps://devzone.nordicsemi.com/thread/512937?ContentTypeID=1Mon, 02 Dec 2024 11:03:58 GMT137ad170-7792-4731-bb38-c0d22fbe4515:dfcf69e9-3788-48af-9d98-ec847d117873Asbj&#248;rn<div style="border:0;color:rgba(0, 0, 0, 1);font-size:11pt;font-style:normal;font-weight:400;letter-spacing:normal;line-height:inherit;margin:0;padding:0;text-indent:0;text-transform:none;vertical-align:baseline;white-space:normal;">Hello Xijunjie,</div> <div style="border:0;color:rgba(0, 0, 0, 1);font-size:11pt;font-style:normal;font-weight:400;letter-spacing:normal;line-height:inherit;margin:0;padding:0;text-indent:0;text-transform:none;vertical-align:baseline;white-space:normal;"></div> <div style="border:0;color:rgba(0, 0, 0, 1);font-size:11pt;font-style:normal;font-weight:400;letter-spacing:normal;line-height:inherit;margin:0;padding:0;text-indent:0;text-transform:none;vertical-align:baseline;white-space:normal;">The documentation we have available for the DFU and functionality on the nRFutil tool is here:<span>&nbsp;</span><a style="border:0;margin:0;padding:0;vertical-align:baseline;" href="https://docs.nordicsemi.com/bundle/nrfutil/page/guides-nrf5sdk/intro.html">https://docs.nordicsemi.com/bundle/nrfutil/page/guides-nrf5sdk/intro.html</a></div> <div style="border:0;color:rgba(0, 0, 0, 1);font-size:11pt;font-style:normal;font-weight:400;letter-spacing:normal;line-height:inherit;margin:0;padding:0;text-indent:0;text-transform:none;vertical-align:baseline;white-space:normal;"></div> <div style="border:0;color:rgba(0, 0, 0, 1);font-size:11pt;font-style:normal;font-weight:400;letter-spacing:normal;line-height:inherit;margin:0;padding:0;text-indent:0;text-transform:none;vertical-align:baseline;white-space:normal;">Best regard</div> <div style="border:0;color:rgba(0, 0, 0, 1);font-size:11pt;font-style:normal;font-weight:400;letter-spacing:normal;line-height:inherit;margin:0;padding:0;text-indent:0;text-transform:none;vertical-align:baseline;white-space:normal;">Asbjørn</div><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/512895?ContentTypeID=1Mon, 02 Dec 2024 09:07:09 GMT137ad170-7792-4731-bb38-c0d22fbe4515:e25f72d8-d0c5-478d-91f2-190eecdd32edxijunjie<p>hi,anybody know?</p><div style="clear:both;"></div>
