nRF52833 cannot use MCUBoot with usbhttps://devzone.nordicsemi.com/f/nordic-q-a/126662/nrf52833-cannot-use-mcuboot-with-usbI tried to fully replicate the example from DevAcademy ( academy.nordicsemi.com/.../) for my project, and added a button and an LED in the overlay. However, once SB_CONFIG_BOOTLOADER_MCUBOOT=y is set, my mcu shows no response when plugged into the usben-USTelligent Community 13Thu, 22 Jan 2026 11:18:04 GMTRE: nRF52833 cannot use MCUBoot with usbhttps://devzone.nordicsemi.com/thread/559348?ContentTypeID=1Thu, 22 Jan 2026 11:18:04 GMT137ad170-7792-4731-bb38-c0d22fbe4515:b560c7d9-d982-40d5-9671-04139c050a0cVidar Berg<p>Hello,</p> <p>Please confirm if you are using the nRF52833 DK or another board. If it&#39;s not a Nordic development kit it may not have the optional 32 KHz crystal mounted, which means you need to change the default clock source to the internal RC oscillator in both the bootloader and application by enabling&nbsp;CONFIG_CLOCK_CONTROL_NRF_K32SRC_RC</p> <p>Best regards,</p> <p>Vidar</p><div style="clear:both;"></div>
