Ive added

CONFIG_BOOT_SERIAL_WAIT_FOR_DFU=y

CONFIG_BOOT_SERIAL_WAIT_FOR_DFU_TIMEOUT=1500

to mcuboot.conf and now if I spam mcumgr -c testDK image list while rebooting I can get into DFU and upload

I commented out some other options in mcuboot.conf (CONFIG_GPIO=n could have been the culprit)

and now it compiles. but now im getting NMP timeout

I changed my defenition to button0 regardles (it looks cleaner)

but Im constantly getting "Serial recovery selected without an entrance mode set". on compile

Button is not necessarily required for DFU over USB.

Is button needed for DFU over USB ? I see its needed for DFU over UART but not USB ?

Hi Ivan,

Have you enabled the proper Kconfigs in your prj.conf for the serial recovery mode?

Also, in case you are only using one button, please change your dts definition for button1 to button0 and add the alias for it

buttons {
compatible = "gpio-keys";
button0: button_0 {
gpios = <&gpio1 13 (GPIO_PULL_UP | GPIO_ACTIVE_LOW)>;
label = "Button 0";
};
}

{
aliases {
button0 = &button0;
};
};
