Build problem with SparkFun nRF52 Boards on Arduino

Development Boards Arduino
1

Hi, trying to build Blink for RedBear Lab nRF51822 using the nRF5 boards support, downloaded to Arduino 1.6.13 on Linux 32 bit OpenSuSE, using

https://raw.githubusercontent.com/spark … index.json

installed with BoardManager.

But build fails with:

…

/home/mikem/.arduino15/packages/SparkFun/tools/nrfutil/0.5.2-SFE/dist/nrfutil dfu genpkg --application “/tmp/arduino_build_367071/Blink.ino.bin” “/tmp/arduino_build_367071/Blink.ino.zip”

fork/exec /home/mikem/.arduino15/packages/SparkFun/tools/nrfutil/0.5.2-SFE/dist/nrfutil: exec format error

and indeed /home/mikem/.arduino15/packages/SparkFun/tools/nrfutil/0.5.2-SFE/dist/nrfutil turns out to be an ARM executable not a i686-linux-gnu executable:

file /home/mikem/.arduino15/packages/SparkFun/tools/nrfutil/0.5.2-SFE/dist/nrfutil

/home/mikem/.arduino15/packages/SparkFun/tools/nrfutil/0.5.2-SFE/dist/nrfutil: ELF 32-bit LSB executable, ARM, EABI5 version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.32, BuildID[sha1]=57df86d5b84818fe7c0bb84b7d15100b607fe520, stripped

Seems that https://cdn.sparkfun.com/assets/learn_t … ux.tar.bz2 (the origin of the nrfutils package) contains an ARM executable instead of the expected processor type:

Could this be fixed please? Im expecting some SparkFun nRF52832 Breakout boards soon and the build for that chip also suffers from the same problem.

Cheers.

I ran into the same problem while trying to upload to my Sparkfun nRF52832 breakout.

As a workaround, the following worked for me (on Ubuntu 16.04) to get a working executable:

cd <some_temporary_scratch_directory>
wget 'https://github.com/NordicSemiconductor/pc-nrfutil/archive/v0.5.2.tar.gz'
tar -xf v0.5.2.tar.gz
cd pc-nrfutil-0.5.2
pip install -U setuptools
pip install pyinstaller
pip install -r requirements.txt
wget 'https://raw.githubusercontent.com/NordicSemiconductor/pc-nrfutil/master/nrfutil.spec'
vi nrfutil.spec
    # replace \\ by /
pyinstaller nrfutil.spec
cp -p dist/nrfutil ~/.arduino15/packages/SparkFun/tools/nrfutil/0.5.2-SFE/dist/

Thanks, almost works for me on OpenSuSE 13.2 too, except that I also needed:

pip install pc-ble-driver-py

also had to edit pc-nrfutil-0.5.2/nordicsemi/dfu/intelhex/init.py to fix a number of syntax errors when run with python 3

print “xxxxx” → print(“xxxxx”)

and

except xxxx, y: → except xxxx as y:

finally the dist/nrfutil is built but when I run it I get:

Traceback (most recent call last):

ImportError: No module named ‘compat’

Failed to execute script main

apparently caused by this line in

nordicsemi/dfu/intelhex/init.py:

from compat import asbytes, asstr

but I cant find this compat module anywhere.

There seem to be many other errors listed in build/nrfutil/warnnrfutil.txt

Ideas?

Cheers.

Looks like my main problem was using python3 instead of python2 (both availbale here)

This works for me:

cd <some_temporary_scratch_directory>

wget ‘https://github.com/NordicSemiconductor/ … 5.2.tar.gz’

tar -xf v0.5.2.tar.gz

cd pc-nrfutil-0.5.2

pip2 install -U setuptools

pip2 install pyinstaller

pip2 install -r requirements.txt

wget ‘https://raw.githubusercontent.com/Nordi … futil.spec’

vi nrfutil.spec

replace \ by /

python2 /usr/bin/pyinstaller nrfutil.spec

cp -p dist/nrfutil ~/.arduino15/packages/SparkFun/tools/nrfutil/0.5.2-SFE/dist/

thanks for getting me so close!

Hope this helps someone else
