Problem solved,

In my case, it was working directory naming issue.

(login to Windows with ID in Korean, so working directory also contains

Korean characters like C:\Users\[Korean characters])

So I change these to English and things now working fine.

Regards,

Hello ziming,

I got same UnicodeDecodeError issue like you.

Could you share how you solve the problem in detail?

Thanks

Hi Ziming,

It appears that its not possible to generate a firmware image using nrfutil without specifying the -sd-req. So you will have to either have a SD present on the device or include a SD in the image.

So your application is not using the RADIO in the nRF52840 at all?

Best regards

Without SD on the device. My application only uses a Master Boot Record (MBR).

I want to know Can I upgrade device without SoftDevice ?

What should I do if I can？

If the SD is present on the device, then you need to use the --sd-req that is identical to the SD that you flashed to the chip. WHich SD version did you flash?

Best regards

--sd-req I used 0xb6,and after I burned SoftDevice to the chip, the upgrade was successful.But i don`t use softdevice,My application only uses a Master Boot Record (MBR).

I want to know Can I upgrade without SoftDevice ?

What should I do if I can？

I try using --sd-req 0xFFFE when I generated the app_dfu_package.zip,and the device don`t have SoftDevice.

The generated command is "nrfutil pkg generate --hw-version 52 --application-version 1 --application nrf52840_xxaa.hex --sd-req 0xFFFE --key-file private.key app_dfu_package.zip"

I use "nrfutil dfu usb-serial -pkg .\app_dfu_package.zip -p COM8" to upgrade,but It still returns NordicSemiException: Extended Error 0x07: The array of supported SoftDevices for the update does not contain the FWID of the current SoftDevice.

Which --sd-req did you set when you generated the app_dfu_package.zip using nrfutil? Try using 0xFFFE.

I have solved the problem.

This is the problem with python2.7，it default encoding is ASCII,Change the encoding mode to GBK.

But I ran into another problem when I was using the DFU USB upgrade.

I use the command is "nrfutil dfu usb-serial -pkg .\app_dfu_package.zip -p COM8",

It return "NordicSemiException: Extended Error 0x07: The array of supported SoftDevices for the update does not contain the FWID of the current SoftDevice". But i don`t use softdevice,My application only uses a Master Boot Record (MBR).

Can you help me how should I solve this problem?

Did you install nrfutil using pip or are you using the nrfutil.exe from https://github.com/NordicSemiconductor/pc-nrfutil/releases?

I changed the version of nrfutil into 5.2.0(Everything else is the same as before)
