I just took a wild guess that someone asking for "plug and play" is new to GPS / Pi and probably not putting a stratum 1 time server in a bunker.  :-)

Not trying to be funny, or nit picking, but you do actually copy the image from the Windows disk file to the SD card.  There is no burning involved, even though that is the common term for it.

HOWEVER, Windows copy won't work, you have to use a program like Win32DiskImager to do it.  There is actually less involved than using Windows copy, but it must be done with a program like that, which is my favorite since it has never failed me making hundreds of SD cards.

Here's a another clue, DON'T FORMAT THE SD CARD FIRST.  And make sure you eject it properly.

My 2 cents

I think one must 'burn' the image onto the SD card, not 'copy'.


My understand is this 17 Gig image file that is created is supposed to set itself up when you power on the Raspberry Pi4b and run.  Am I wrong in that assumption?  I've downloaded this file twice now on a limited data throughput device and can't keep doing this as I'll run out of data for the month.

Re: W3DJS Raspberry Pi Ham Radio Image v2.0 Released - INOP

When I set the image up on a Pi 3b and booted for the first time. I had to let it sit for quite a while. Pretty sure it was running scripts and updates to the software. I think I had to reboot once and maybe twice. What seemed like the blank screen and it just sitting there it was apparently doing some first time boot activities in the background. This may be problematic if you are expecting to connect to the internet via Wi-Fi. The image is set up to run as a hotspot for other to connect to the device. This has proved to be an issue for most. Personally I had mine hard wired to my network and I had to run the command “KillHotspot” (case matters) from the terminal for even my wired connection to work properly. Once the hotspot was turned off anything that needed to be run over the net worked on the wired connection. Do not expect the Wi-Fi to function as a client and be able to connect to your wireless network. There are other discussions and commands mentioned to fix that issue.

 

My suggestion, burn a new image and start over. The file you downloaded is probably fine, on first boot be patient and let things run for a while even though it seems it’s doing nothing.

 

Thank You,

Brian N2KGC

Win32DiskImager did the trick for me.  It loaded correctly on to the SD card and configured the program at power-on so everything is running as described.  It running just fine on a Raspberry Pi4b now.

Thanks for the input on this problem.  Really appreciate the help.

For writing disk images (typically .iso files) you ought to give Balena Etcher a try:


Etcher can read many compressed image types, and it also has some built-in smarts to prevent writing to a disk other than that memory card you intend to use. It's quite handy to have around. 
-----------
Having said that... it's not clear to me which file you have been downloading. Is it via the .torrent that's in the groups.io Files area? If so, the big file is "HamRadio_W3DJS_Pi_v02.img" and Etcher can burn a .img file straight away.

If the file you're downloading is indeed a .tar.bz2 file... I'm not familiar with that release. Uncompressing the .bzip2 file, and then untarring the tar file... what's in there? Is it just the three files from the torrent (the .img file plus two read me docs?)

Hope the Etcher info isn't a red herring for you; meanwhile, anyone that wrestles Pi images will enjoy having that utility in their toolbox...

The file that you get after you "unzip" it is a disk image that needs a special (but free and easy to get) program to copy it to tbe SD card.  The disk image includes the unnamed boot files that need to be in the correct place on the disk in order for things to work right.

When the Pi first starts up it's pretty "stupid" and only knows enough to start reading data from a specific spot on the SD card.

The data from the special spot is a small program that gives the  Pi enough "smarts" to find the actual operating system files.

Anyway, the regular copy program won't put the unnamed boot files in the correct spots on the SD card.

Win32DiskImager is, I think, what you need to do this on a MS Windows machine.  dd  is the program for Linux. 

Be careful with dd.  It relies on the user to know the correct syntax for the command...there is no safety net....and if you get the syntax backwards, it will happily over write you regular disk.

I have tried it at least 4 times now myself on a RPI4 with nothing but a blank screen afterwards myself.

 

So I suspect it could be something with my version of the 4gig rpi4.

 

I tried it on a 3b a couple times, at it will at least try to expand out there, but then starts bombing out with tons of errors.  Then lots of authentication errors.

 

So no joy for me either.

Re: Raspi, Icom 7200 and GPS, cannot make this combination work

John Schultz
 

The more I contemplate this issue, the more I feel like setting USBAUTO="false" is just a workaround for a different problem.  This does not happen for Yaesu radios, even those that use the same cp210x converter (my FT891 for example).  For some reason our Icom radios are being detected as a source of PPS for GPSD.  Running dmesg|grep -i tty immediately after connecting the rig will reveal that it is showing up as a GPS source.  Immediately after the cp201x converter is attached to USB0 the next line is pps pps1: source .....  This is USB0 (The Radio) being added to the GPSD daemon.  The real fix is figuring out why this happens and how to stop it.



It is possible to remove a specific device from the GPSD device pool from what I can tell.  Scripting this removal may be a better workaround than simply setting USBAUTO to false.  This seems like it would be a better solution since setting USBAUTO to false seems to indicate that if we boot up our system and then plug in the USB GPS device we would have to reboot for detection.  I need to verify this behavior this weekend.

Any thoughts on this issue?

Thanks,

Do you use wjst-x for FT8 at all, because the only other issue before I'm 100% is control of receive audio to adjust RX db levels. alsa only seems to control output audio. And have been resorting to manual control on rig, which defeats the purpose for remoting.

Sounds to me like the image you are using is ready to go.  Plug it in and reboot, since you had to disable usbauto.  Then when it starts to flash try that same command again.  Should see an X next to nmea.
