Start button in UI not doing anything

[CountParadox]

Hey,

Just finished installing everything to use rx_sdr with my hackrf, Everything starts and I get no errors in logs, when I load up the web UI, i see the elements in the log correctly, but when I click the start button, nothing else happens.

Please try for yourself: https://sdr.rei.moe

With no errors I'm at a loss what to check :(

[jketterl]

I didn't get to see much, but that looked like an "old" OpenWebRX (i.e. the one from the ha7ilm repository that is discontinued). It's down now, so can't check in detail. That version did not support https URLs.

[CountParadox]

Oh! That could be it... Hmm

[CountParadox]

making progress,

So I understand the address already in use part, as it seems to run itself on boot. But when I run it manually, it finds the HackRF One and loads it, but the web UI tells me that there is no SDR available.

[jketterl]

Being "available" at this point only means that all the required programs to run it have been found. It may have failed in another way at a later point. I'm assuming it's a packaged install, so you should be able to get the logs with sudo journalctl -u openwebrx. You can also halt the instance started at boot with sudo systemctl stop openwebrx, but please be aware that running manually on the console will likely leak processes (most likely csdr, and in the case of HackRF, possibly hackrf_transfer).

getting somewhere!

Illegal instruction?

Maybe my HackRF has an old firmware?

[jketterl]

that could be coming from either hackrf_transfer or, more likely, csdr... csdr is making use of the AVX instruction set to optimize performance. Unfortunately, that is unavailble on older CPUs.

[CountParadox]

ooh! Maybe because its virtualised... let me try somethign

[CountParadox]

Eureka!

you were spot on!

It was using a virtualised kvm CPU, I switched it over to use the Host CPU and we're running!!

Thanks very much :)

[jketterl]

awesome :) enjoy :)
