According to the steps, dfu can be done normally on 52840-dk in ncs v1.4.0 versionen-USTelligent Community 13Tue, 10 Aug 2021 10:20:30 GMThttps://devzone.nordicsemi.com/thread/324186?ContentTypeID=1Tue, 10 Aug 2021 10:20:30 GMT137ad170-7792-4731-bb38-c0d22fbe4515:43f72285-ad91-4c10-b6f8-3b3306f03145zero<p>Hi Charlie,</p> <p>Tried the solution you linked: Add CONFIG_UART_CONSOLE=n in usb_cdc_acm_log_recovery.conf, it can run normally on 1.6.0, but I still have a question: Why should CONFIG_UART_CONSOLE be set to n to jump to the application?
