ssh.txt didn’t work for me
Valid file names for enabling SSH:
- ssh
- ssh.txt
- SSH
- SSH.txt
Maybe the file extension was hidden by windows?
That would make the actual filename ssh.txt.txt
(Or the other options were introduced somehwere along the way)
That’s one of the first things that I un-hide on Windows. So annoying.
But this was a year ago when I imaged last my SD card, so things might have changed.
This has happened with me once when “show extension for known file type” was unchecked in “folder options”. Since then I started using extensionless version i.e. ssh or SSH, just in case.
This is why I dumped *indows and only use *nix
Cheers!

You built 3.7.0, not 3.7.0.1
Thanks for the tip.
Just in time.
I have just now finished reimaging microSd card with Armbian 5.7.5, and have done apt update
, apt upgrade
, apt dist-upgrade
. Was about to start building 3.7.0 again when saw your reply.
Will now use git checkout v3.7.0.1
.
As per your advice, now built v3.7.0.1 - THANKS

Wow that’s not a very helpful error message.
How old is the software you run on that thing, maybe the C++ stuff or soapySDR stuff is not recent enough.
Hmm that should be the same as on the RPi.
No clue to be honest.
Can you show the output of rtl_test
?

The Armbian image is the latest
pi@orangepipc:~$ uname -a
Linux orangepipc 4.19.20-sunxi #5.75 SMP Sat Feb 9 19:02:47 CET 2019 armv7l GNU/Linux
.
Before building any packages, I did following:
sudo apt update
sudo apt upgrade
sudo apt dist-upgrade
Let’s check rtl_test, maybe the dongle serial doesn’t match?
(Hmm, that shows a different error for me)
.
(1) The /etc/default/dump978-fa file
ENABLED=yes
RECEIVER_OPTIONS="--sdr driver=rtlsdr,serial=00000978 --format CS8"
DECODER_OPTIONS=""
NET_OPTIONS="--raw-port 30978 --json-port 30979"
.
(2) The piaware-config
pi@orangepipc:~$ sudo piaware-config -show uat-receiver-type
sdr
pi@orangepipc:~$ sudo piaware-config -show uat-sdr-device
driver=rtlsdr,serial=00000978
.
(3) The rtl_test -t
pi@orangepipc:~$ rtl_test -t
