Creating an image file to DFU on SDK8.0

[kevin.lee]

hi, to do DFU on SDK 8.0, if use the MCP on PC, it wants to select a zip file, if select a hex file, it will fail. I have created the bin image,but I can’t create the zip file by nrf.exe. can you give some advise about howto create the zip file for MCP to do DFU more detail, and the MCP on Android(V2.0.3) can’t do DFU either select hex file or zip file, is there any update version for android? Thanks Kevin

How to create a zip-file that contains the bin-file and the init packet is described here: developer.nordicsemi.com/.../a00092.html

A typical command would look something like this: (for SD v8.0.0)

nrf.exe dfu genpkg app.zip --application nrf51822_xxac.bin --application-version 0xffff --dev-revision 0xffff --dev-type 0xffff --sd-req 0x0064

If you tried this, but failed, please include the commands you wrote and any error messages you got, in your question.

The newest version of the MCP for Android is 2.1.1. You can also try to use the nRF Toolbox app for Android, it includes a separate DFU application.

EDIT

The error message you posted in the comment is the same as in this thread: devzone.nordicsemi.com/.../

The issue is that you don't have permission to access the .zip file, probably because you don't have write permissions to the folder. Try opening the terminal as an administrator.
