NWDR16 image release announcement

Basil Gunn

Latest RPi image has been updated to at
this location:

There were 8 image releases last year. This is the 2nd release of
2020, there may be one more this year.

You do NOT have to download the latest image to run the lastest
kernel/programs. You can get the most up-to-date kernels/programs by
doing the following with your current running image:

sudo apt-get update
sudo apt-get dist-upgrade
cd n7nix
git pull
cd config

You can verify & update image program versions with these scripts:


The script maintains current versions of these HAM programs:
js8call wsjtx flxmlrpc fldigi flrig flmsg flamp fllog

Current version numbers of programs on the image are kept here:

Before you update your image, capture any configuration changes you
might have made like current alsamixer settings. Run &
make a copy of result.

It is recommend having at least 2 mSD cards & not over writing your
current mSD card. NOTE: MINIMUM recommended microSD card size is 16GB.

Please follow the "Getting Started Guide" from the UDRC Wiki.

The current image has Linux kernel (4.19.97) that includes Anna's main
line TI tlv320aic device driver which supports the UDRC / UDRC II & DRAWS
hats. To view the changelog for this kernel go here:

Included in this image is gpsd ver 3.20.

NOTE: Direwolf version 'dev 1.6 E' has a problem building & running
with version 3.20 gpsd since the gpsd program updated their API version
number which is NOT handled by direwolf.
See reported issue here:
If you use direwolf as an app that uses gps instead of just a sound
modem do not use this image, or install gpsd version 3.19.

On first boot, if you have an attached monitor, you will see the piwiz
configuration screen used on current Raspbian images.

If you are using a Raspberry Pi 4 and your monitor is blank then add
this to /boot/config.txt to use HDMI safe mode.

If you have any problems with this image please include:
- output of script with your problem description.
- *ALL* console output showing the problem

Since I don't see a symptom of this problem with the lastest image
nwdr16.img I assume you are updating an older image.

If I search the udrc forums I find this entry form last July:,,,20,0,0,0::relevance,,,20,2,0,32661582

ldconfig -p | grep -i libjpeg (libc6,hard-float) => /usr/lib/arm-linux-gnueabihf/ (libc6,hard-float) => /usr/lib/arm-linux-gnueabihf/

To install libjpeg9-dev

sudo apt-get install libjpeg9-dev

Now ldconfig should display

ldconfig -p | grep -i libjpeg (libc6,hard-float) => /usr/lib/arm-linux-gnueabihf/ (libc6,hard-float) => /usr/lib/arm-linux-gnueabihf/ (libc6,hard-float) => /usr/lib/arm-linux-gnueabihf/
