nrf5340 ncs USB+DFU mcuboot_menuconfig

[wangrj]

The MenuConfig page of SEGGER IDE (ncs1.9.1)：

How should I configure this interface if I want to configure usb DFU and trigger upgrade mode via button: 1.boot_usb_dfu\Use gpio to detect whether to trigger dfu mode ,or   2.MCUBOOT_SERIAL\BOOT_SERIAL_DEVICE\BOOT_SERIAL_CDC_ACM  . Or check both of them. What's the difference between them? Because I think CDC ACM is a kind of USB. Do trigger GPIO need to be configured with the same pin?

Hi,

There are some samples that might be useful. You could take a look at SMP Server Sample and USB DFU Sample in the documentation.
SMP server sample requires MCUboot. When SMP server is running and mcumgr is  used for communication, DFU can be tested for both Bluetooth and UDP.
USB DFU sample also uses MCUboot and is dependent on DFU image manager and partition layout.

Hi

thank you so much !

I successfully ran the usb duf sample  , but i can only find 2 command about dfu-util to download new image and get the old image from board .

Now how can i  download the file "dfu_application.zip"    by command dfu-util  like mcumgr     ?   

Does dfu-util have as many rich functions as mcumgr, such as viewing current image information,Confirm new image,Download file from File System ,etc....

Best regards

Hi,

You can read about the dfu-util  options on dfu-util home page and dfu-util options and examples.
