Creating zip file for DFU in linux, nRF5 SDK11.

[Jake]

How can I create zip package for DFU in Linux. I'm using nRF5 SDK version 11. I'm working in Linux(Ubuntu 14.04).

I'm trying to zip package file for DFU in linux. When I create zip in linux and unzip it, manifeste.json file is looked like this.

$ cat manifest.json {
    "manifest": {
        "application": {
            "bin_file": "MY_APP.bin",
            "dat_file": "MY_APP.dat"
        }
    } 
}

But, if I generate it in Windows, using below command, unziped manifest.json is like this.

"c:\Program Files (x86)\Nordic Semiconductor\Master Control Panel\3.10.0.14\nrf\nrfutil.exe" dfu genpkg --application MY_APP.bin --application-version 0xFF --dev-revision 0x1 --dev-type 0x1 --sd-req 0x80,0xfffe MY_APP.zip

{
    "manifest": {
        "application": {
            "bin_file": "MY_APP.bin",
            "dat_file": "MY_APP.dat",
            "init_packet_data": {
                "application_version": 255,
                "device_revision": 1,
                "device_type": 1,
                "firmware_crc16": 61844,
                "softdevice_req": [
                    128,
                    65534
                ]
            }
        },
        "dfu_version": 0.5
    }
}

How can I create zip package in Linux.

Hi,

To generate the .zip package for DFU in a linux environment you can use pc-nrfutil. Mergehex can be found in the command line tools for linux, it is also rather straight forward to script yourself.

An older guide for generating this packet can be found here, note that some paths and tool names might have changed.

Best regards,

Øyvind

Hi, bg2bkk.github.io/.../ this post is my dfu with SDK10 and ble_app_uart, the chip is nrf51822 QFAA. I am not good at Engish and hope this can make sense.
