Zip file failed to upload for ble_secure project

Newbie

Hello, I am working on ota ble_secure project. I have created a zip file which is the last step and copied this file to my smart phone so that I can upload it using nrf toolbox. The upload fails. I am not sure which files to include to create a zip package. I am attaching my zip package as well as the files that I used to merge.app_dfu_package.zip. The hex file is nrf52832_xxaa_s132.hex.

The log file of error is log.txt

Sdk which I have is www.nordicsemi.com/.../nRF5-SDK

I am using this project in sdk sdknordic\examples\dfu\bootloader_secure\pca10040

Left side is new sdk and right side is old sdk. bootloader.PNG

Log file New Text Document.txt

New log file errorlog.txt

    Could you point me where you found "nrf51latest13alpha SDK" ? There is nothing like that from Nordic.

    If you only update the application, you only need the application .hex file. This find you can find in the _build folder after you compiled your project.

    After that you use "nrfutil.exe dfu genpkg" to generate the .zip file. For example if the hex is yourapplication.hex the script can be:

    nrfutil.exe dfu genpkg app.zip --application yourapplication.hex --application-version 0xffff --dev-revision 0xffff --dev-type 0xffff --sd-req 0xfffe

    Hello Hung, I dont remember the source but I have downloaded new sdk nRF5_SDK_13.0.0-1.alpha_055eef3 from nordic website. I have tried the commands suggested by you. It gave me error Invalid crc error. Than I followed the link devzone.nordicsemi.com/.../ and github.com/.../pc-nrfutil

    After this I tried with the new zip file but now it gives me error unknown (8202) error.

    Thanks, Shailav

    Hi Shailav,

    You are using SDK v13, then you need to follow instruction in SDK v13. In SDK v13 it uses secure bootloader not the legacy bootloader so what I suggested won't work.

    You should follow this intruction.

    (Ignore step 4 in the "Testing" section. )

    Hello Hung, This is the command that I prepared following the instructions suggested by you.

    nrfutil pkg generate --application C:\Users\Ambimat\Desktop\sdknordic\examples\dfu\bootloader_secure\pca10040\arm5_no_packs\_build\nrf52832_xxaa_s132.hex --application-version 0xff --hw-version 52 --sd-req 0x8C --key-file C:\Users\Ambimat\Desktop\sdknordic\examples\dfu\bootloader_secure\pca10040\arm5_no_packs\_build\my_secret_private_key.pem app.zip

    Now my challenge is where will I find the bootloader.hex file? I think I need to add this --bootloader image: an image of a bootloader and the version of the bootloader. Without the bootloader I created zip file and I am getting error as DFU file not found. Thanks, Shailav

    Hello, I am following this link devzone.nordicsemi.com/.../ Do you recommend me to use this? I will make changes according to my sdk. I need following files according to this link app_valid_setting_apply.hex ble_app_hrs_dfu.hex bootloader.hex s110_nrf51822_7.0.0_softdevice.hex

    Can you tell me where will I find all the files?

    Do I need to merge the files as described in this link? Thanks, Shailav
