DFU Zip file creation

[Nate]

I have created files before with s110 sd8 with the nrfutil.exe utility using a bat file.

nrfutil.exe dfu genpkg --application nrf51422_xxac_s110.hex --application-version 0xffff --dev-type 0xffff --dev-revision 0xffff --sd-req 0x64 zippackage.zip

It use to work but now the android toolbox application doesnt recognized the zip file. It is grayed out in the selector.

If i select it with a file manager it says file format error.

If I take the zip file and unzip it and use the bin file and the dat file i can upload it to the device.

Has something changed in the nrfutil.exe? I keep it up to date i with the latest versions.

Which version of the nRF Toolbox android app are you using?

[Nate]

Its the same on IOS and android with the latest version. android is 1.16.3

Do you see the same behavior when not setting a SD requirement?

nrfutil dfu genpkg <name of firmware image>.zip --application <name of app hexfile>.hex --application-version 0xFFFFFFFF --dev-revision 0xFFFF --dev-type 0xFFFF --sd-req 0xFFFE

Could you upload the zip file that generates the error?

I am having this problem too.

I never got this fixed and still am having problems with zip files. I have been unzipping the file and using the bin and dat files. I'm using a windows 10 machine Nate
