    Hi all. After 40 years in the aviation industry I am finally delving into the new and (to me) confusing world of feeding.

    First, equipment.
    iMAC i7 32GB RAM Catalina (latest)
    Pi4 4GB
    Noolec Smartee SDR
    Good power and case with fan. brand new Micro SD Card 32GB.

    I have burned the image adsbx.1.0.3.img to the Micro SD card (using Etcher) with edited ads-config.txt (with my correct location) and also the file for connecting to my WiFi network.
    After inserting the card into the Pi4 and switching on, there is a flurry of actions with green "OK" showing against each one.

    Eventually the line "Starting Update UTMP about System Runlevel Changes..." appears. At this point the screen stops scrolling. After a few minutes I hit Enter on the attached keyboard and the line "Started Update UTMP about System Runlevel Changes." appears.

    The screen then stops again at this point. (see screenshot)

    I have formatted the SD card and tried to burn the IMG again with the same results.

    Forgive me if this has been covered elsewhere but I did look through a considerable number of threads without any reference to this issue.

    Any help much appreciated.

    Regards to all,

    Eddie Allison

    Seems it just completed booting but show the messages in a somewhat strange order.

    Have you tried accessing the IP it prints or just pressing Enter and logging in?

    See it prints an IP address, put it in your browser like this:
    http://192.168.1.191

    Thanks for the prompt reply. I have tried accessing the generated IP without success. It simply can’t open the address. Should I have a Port suffix perhaps?

    On the point of hitting Enter and just logging in? This results in the following problem.

    I tried this several times but it is as though the Pi is incredibly busy and it takes up to a minute to accept keyboard entries - often timing out. Sometimes it seems to ignore input completely or goes out of sync withe password appearing in the login line or vice versa.

    i didn’t mention it 1st time round as I didn’t want to overload the support contributors!

    Any other thoughts?

    Cheers,
    Eddie

    I see now what it's doing, resizing the root partition, that only happens on first boot.

    Maybe that is failing because the sd-card isn't working properly?
    Hard to guess.
    Maybe burn the image, boot it, wait 10 minutes and then power cycle?

    Feel free to just try the official Raspbian image if you're having issue with this one?
    If you get that up and running, you can just run these two installs and should be feeding as well:
    https://github.com/wiedehopf/adsb-scripts/wiki/Automatic-installation-for-readsb
    https://github.com/adsbxchange/adsb-exchange

    Added interfaces for the above:

    Thanks again for the help. I am moving aerial videos from a 2nd SD Card and will format this then try again. In the meantime I have attached a 2nd screen shot which happens after I tried about 100 times to login and finally (apparently) succeeded. Does this look normal?

    If there is just some grass-roots incompatibility here I will try the links you kindly provided. Since this is day 2 of me ever having laid eyes on a Raspberry Pi, I am on a near vertical learning curve, so I hope you don't mind me asking a couple of general pi-based questions?

    1. Can you point me to the Official Raspbian Image you mention, please?
    2. If I get the official image installed, go I go the links you provided on my MAC or on my Pi
    3. If the correct answer to 2 is the MAC, how do I then add these to the SD card. Are they burned with Etcher or simply copied from MAC to SD?

    Again, I appreciate you taking time to respond to a newbie fresh out of the box.

    Well seems it finally succeeded expanding the partition.

    Have you tried accessing the webinterface?

    Not sure trying Raspbian is the right move for you. Anyhow here: https://github.com/wiedehopf/adsb-wiki/wiki/Raspbian-Lite:-ADS-B-receiver

    Don't run sudo bash "some random internet script" on your IMac.
    It's somewhat necessary on the RPi because actually explaining ppl what to do just takes too long.

    It appears to be working. I have 2 smiley faces on the myip page. Presently, naturally, there are zero aircraft within 100 miles of me! (except on 32 miles away but he is at 2,000ft). Does that mean I am up and running? Is there a way that I can identify my feeds on the standard map or do I need to view these in the web interface locally? I don't have a map there incidentally, just the usual web page with controls but no map.

    Thanks again and hopefully I am done bothering you!

    Cheers,
    Eddie

    https://www.adsbexchange.com/myip
    That should have a link to what your receiver is seeing.

    But i'd always use the local webinterface.
    When you input http://192.168.1.191/ (or whatever the current IP is), there should be a link to a local map interface.

    Don't run any of the scripts i mentioned above on the adsbx image, that already has everything.
    Running scripts there (depending on which script) is gonna cause issues.
