Device not restarting after copying bootloader during DFUhttps://devzone.nordicsemi.com/f/nordic-q-a/109388/device-not-restarting-after-copying-bootloader-during-dfuHi, We&#39;re using secure bootloader example for BLE based DFU of our nRF52840 based custom board employing nRF5 SDK 17.1.0 and S140 SoftDevice (7.3.0). Everything is working great except when the bootloader is updated and it needs to be copied internallyen-USTelligent Community 13Mon, 18 Mar 2024 12:51:25 GMTRE: Device not restarting after copying bootloader during DFUhttps://devzone.nordicsemi.com/thread/474325?ContentTypeID=1Mon, 18 Mar 2024 12:51:25 GMT137ad170-7792-4731-bb38-c0d22fbe4515:bb234109-40c3-4ee8-928d-d0d6bd1f8e2fVidar Berg<p>Hi&nbsp;<span>Adnan,</span></p> <p>The issue&nbsp;occurs because the bootloader copy routine in the MBR does not return execution to the bootloader until after the copying process is complete, and during this time, you will not have control over the GPIO configuration.
