Nordic nRF52832 DFU problem

[hamdi.tn]

Hi everyone,

so i spent the day trying to flash an nRF52832 in DFU mode with nrfutil.exe.
no matter what i do or file i choose it always end with

IOError: [Errno 2] No such file or directory: 'c:\\users\\***\\appdata\\local\\temp\\nrf_dfu_pkg_kplm5y\\unpacked_zip\\manifest.json'

am running command promp as administrator. tried different OS windows 7 10 and linux.
changed Temp directory in windows config.

and am out of idea.
Help.

Yap same error, IOError Errno2
I posted there but those forums are not as reactive as EEV 
anyway i walked my way around this issue by using the J-Link programmer instead of DFU.

In case it helps, here's some Makefile rule to call nrfutil. We're using the python
version and this is for nRF51, so the newer stuff may be different. This runs on
a mac, so will probably be the same for linux.

Code: [Select]

OTA_ASSET_APP        := $(RELEASE)/over-the-air/$(APP_TAG).zip
OTA_ASSET_BOOT       := $(RELEASE)/over-the-air/$(BOOTLOADER_TAG)-$(VERSION_SOFTDEVICE).zip

# The nrfutil program accepts the softdevice image as either a .hex or a .bin file
# However, the .bin version will cause nrfutil to also include the MBR in the
# over-the-air image, which is incorrect. Passing the original .hex file of the
# softdevice image (directly from the SDK directory) avoids this problem.
