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.

I am having this problem too.

Have you tried using pc-nrfutil? Its a python based version of nrfutil, here is the link to the github page.
