https://devzone.nordicsemi.com/f/nordic-q-a/66075/how-to-modify-nrf52820-dfu-to-nrf52833Hi, I use DFU secure_bootloader pca10100e_usb example to modify to nrf52833 DFU. But when I execute, I get stuck in this line, as shown below. In configuration, I already change device to &quot;nrf52833_xxAA&quot;, IROM start address 0x74000, size 0xA000en-USTelligent Community 13Mon, 21 Sep 2020 02:00:08 GMThttps://devzone.nordicsemi.com/thread/270435?ContentTypeID=1Mon, 21 Sep 2020 02:00:08 GMT137ad170-7792-4731-bb38-c0d22fbe4515:cab54a14-939f-4d76-b549-7bda6a7f5558JerryLin<p>Hi Simonr,</p> <p>Thank you for your reply, I will try again.</p> <p>Best Regards</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/270345?ContentTypeID=1Fri, 18 Sep 2020 13:18:07 GMT137ad170-7792-4731-bb38-c0d22fbe4515:ab585fc9-4c99-4de3-ab30-a512b657023eSimonr<p>Hi</p> <p>I have notified the SDK team that there is no pca10100_usb example, and it will hopefully find its way into a future release of the SDK. It should not be too difficult to edit the project to run on the nRF52833 instead of the emulated nRF52820 hardware. You can follow the<a href="https://infocenter.nordicsemi.com/topic/sdk_nrf5_v17.0.2/nrf52820_user_guide.html"> Developing for nRF52820 guide</a> on the Infocenter and make sure you revert every step in the Hardware emulation of nRF52820 section, as that should be all the changes that are done to that project.</p> <p>Best regards,</p> <p>Simon</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/270213?ContentTypeID=1Fri, 18 Sep 2020 06:09:34 GMT137ad170-7792-4731-bb38-c0d22fbe4515:43bc084b-6a19-4184-8316-9dd3028b388cJerryLin<p>I using USB DFU</p><div style="clear:both;"></div>
