Hi!
Today i try to install horus on Jetson Nano.
Os Ubuntu
Instalation was proceed without problem but problem is with start
I give log as below and i cannot find core that problem

Unsure exactly what is going on here.

It looks like something in the decode chain is breaking, hence that 'illegal instruction' report.

When you built horusdemodlib, there's an option to run some ctests described here: https://github.com/projecthorus/horusdemodlib?tab=readme-ov-file#testing

I'd be interested to know which of these (if any) are working for you.

You can also run one of these tests from within the horusdemodlib/build/src/ directory:

cat ../../samples/horusb_iq_s16.raw | ./horus_demod -q -m binary --fsk_lower=1000 --fsk_upper=20000 - -

This should output:

Setting estimator limits to 1000 to 20000 Hz.

OK, so at least the horus_demod binary runs correctly! That's a start...

Unfortunately you're probably going to have to tease apart the different commands run in that final command that starts everything up to figure out which one is breaking..

darksidelemm · 2024-08-23T09:33:16Z

Just furthering this, you can see at the bottom of start_rtlsdr.sh that there's a bunch of commands piped together:

rtl_fm -M raw -F9 -d $SDR_DEVICE -s 48000 -p $PPM $GAIN_SETTING$BIAS_SETTING -f $SDR_RX_FREQ | $DECODER -q --stats=5 -g -m binary --fsk_lower=$FSK_LOWER --fsk_upper=$FSK_UPPER - - | python -m horusdemodlib.uploader --freq_hz $SDR_RX_FREQ --freq_target_hz $RXFREQ $@

We can break this out into a few different commands to test (You'll have to modify this line in the file)

rtl_fm -M raw -F9 -d $SDR_DEVICE -s 48000 -p $PPM $GAIN_SETTING$BIAS_SETTING -f $SDR_RX_FREQ

NOTE - this will spit samples out to the terminal, so expect lots of garbage.

then adding horus_demod:

rtl_fm -M raw -F9 -d $SDR_DEVICE -s 48000 -p $PPM $GAIN_SETTING$BIAS_SETTING -f $SDR_RX_FREQ | $DECODER -q --stats=5 -g -m binary --fsk_lower=$FSK_LOWER --fsk_upper=$FSK_UPPER - -

You can also test the decoder by itself, though it wont do much.

python -m horusdemodlib.uploader --freq_hz $SDR_RX_FREQ --freq_target_hz $RXFREQ $@

Okay
First section react acc. to predict, start and generate garbage
Test with demod also start but also give on end section unknow me data:

So it sees like it's the python code itself? That's very odd if that's the case.

What happens if you just run:

python -m horusdemodlib.uploader

(noting you will need to enter your venv first.

Now something more understand :)

Sounds like your venv might not be setup with all of the required libraries then?

Read the instructions here please: https://github.com/projecthorus/horusdemodlib/wiki/1.2--Raspberry-Pi-'Headless'-RX-Guide#25-installing-the-horusdemodlib-python-library

You need to be using pip to get the required packages available within the venv...

... then I am extremely confused why requests isn't found when you run the python -m horusdemodlib.uploader command.

I'd suggest removing the venv directory and starting that again...
